Vertical mode is also useful because some games actually have you holding the 3DS vertically like a book. Mario & Luigi: Bowser's Inside story comes time mind for a few fights.
Former DS/3DS game dev here: Those bars are system resource indicator. The kit you got is using one of the first firmware version for this unit (there have been multiple versions of the devkit) And that cartridge slot is never really used.

Linus, that's the Wii Classic Controller Pro which did in fact make it to market :P also i'm shocked that they didn't irreversibly brick this system in the filming of this video
Funfact: That "development" controller was actually released to the public as the "wii classic pro controller" It even had some special editions like a golden one from goldeneye 007 and a red one from Xenoblade Chronicles.
i like how linus finds a strandard wii classic pro controller and hes like "omg this is way better than the original" when the only difference is the coloring, he was confusing the classic with the classic pro
@@HungryFox02 the L and R buttons on the Classic controller (the one without handles) are analog. You should be able to test the controller using Brawl and lightly press the button to make a thin shield.
@@zero9112 brawl doesn't have light shields. What you're describing isn't possible. There are a handful of other Wii games that actually do support the original Classic Controller's analog triggers though, such as some of the Need for Speed games
Fun fact: that development Wii Classic Controller with the handles actually made it to retail as the Wii Classic Controller Pro, most prominently marketed alongside the Wii release of the Goldeneye 007 remake.
The Nintendo 3DS is pretty special to me, since it was my first console. After homebrewing it I also put some of the Dev-Apps on it. Love seeing Linus messing around in these and showing the dev hardware in detail. Great video!
It's very unlikely the FPGAs are to swap out functionality in the main CPU or GPU. They generally aren't very good at stuff like that - they are usually not big or fast enough to do that (there are high end ones that probably could, but you don't want to know the price). They are probably used for things like glue logic or custom functions, perhaps related to debug or video capture, where it didn't make sense to put a whole board full of logic chips. They could also have been used for things like peripheral controllers and the like, perhaps before they had whatever custom silicon would be in the final device.
I would agree. Although the hardware from the 3DS is low end even for the era I doubt that they would just put the CPU in a FPGA. Specially since the 3DS CPU is not a special hardware. Its your run of the mill ARM CPU. A dual core ARM11 with a PICA200 as GPU. The main difference is that the 3DS also has a ARM9 that controls other stuff (and you can play with both ARM9 and ARM11 at the same time, both can run custom code). Probably the FPGA is there to glue them together. I think the whole processing unit is spread between all boards, I couldn't see a board with more than one "main" chip and on a retail they are discrete chips.
@@manoftherainshorts9075 Mister has a Cortex A9 on it and a much newer Cyclone V. Also, until now the limit of Mister is something close to a PSX. A 3DS can emulate a PSX (although slowly) on itself. Its very hard and costly to put a "modern" architecture CPU running at hundreds if not thousands of megahertz on a FPGA. And ARM CPUs are generic enough to be cheap to purchase instead of trying to build. Mister try to solve the issue of older more specialized hardware that aren't so generic.
@@manoftherainshorts9075 Quite true. But those are very old CPUs being emulated on modern FPGAs. To explain, the SNES processor might have been a 1um process (can't find exact numbers). The FPGA the Mister uses is 28nm (that's 0.028um). It's not that FPGAs can't emulate CPUs (they certainly can - lookup softcores), but, all other things being equal, an FPGA that can emulate a contemporary CPU will be very expensive, assuming it can do it at all.
The "developer board" is probably an ICE (in circuit emulator), most console development kits have this circuit that sits between the CPU and the rest of the system to allow you to do things such as breaking the execution of the program and reading the CPU registers and the memory of the system etc etc etc.. It's how you can do breakpoints on an external system among other tricks.
I kinda hope game manufacturers enjoy seeing their old devkits get shown in videos like this, imagine developing something like this, and then the public never gets to know about the feat of engineering that it was
That capture USB: I recall that for the Wii dev kit, you had the ability to "fake" high rez when you took a screenshot, the machine would take a ton of screenshots then come up with a high rez composite.
if you mean the 3ds thats basically just a screen no those arent that fragile... plus it was super light cuse there were no other internals except a little display driver for the screen and the 3ds on its own is very sturdy design. ive dropped mine like a million times and it barely shows a scratch from it @@TheRetroMess
That controller Linus was using actually did make it to market as the Classic Controller Pro. The dev one is a weird mix of parts from the white and black models though. Something about this video has awakened my nostalgia for when the 3DS was first announced and seemed like a crazy premium product. Thanks!
You need to update to Luma 11.0 since in September there actually was a new firmware update for the 3ds (yeah crazy huh?) I mean there could be a ton of other problems with whatever firmware that 3ds is running, but thats normally what you would need to do with a Luma 3ds to update firmware.
@@Sanrasxz The 3DS part of it probably runs retail firmware. The development apps on the 3DS part most likely use connections that are simply severed in a retail product but are connected to the debug board within the dev kit. Alternatively they could use special codes over an otherwise used connection, either way the actual 3DS part is probably the same as a retail system.
While Nintendo is way bigger than LMG, LMG probably has better than average lawyers on retainer so while they certainly exhibit a bit of hubris with these videos, it's no doubt a move they make after careful calculations.
A lawsuit Nintendo won't win since they're not actually pirating and using laws that were set a long time ago about VCR and cassette tape recording where we the consumer was given the "Right to copy as a backup" The only grey area are the dedicated emulation devices that don't reverse engineer the console software, but rather run the Nintendo firmware in a virtualized environment.
19:32 someone tell Linus there is a tool called "Locale Emulator" and during XP days you could install Microsoft's own local emulation layer "App Locale" as well. NtLea was another option. All three could co-exist (each worked slightly different and thus the applications would run with one tool, but not with the other), but mainly "Locale Emulator" survived to this day.These tools work with like, I'd say, 97% of the software which require Asian locale settings. At the very least, I only have like a handful of games or software which do not run with the locale emulation. I have likely used it on a multiple of hundred games so far, for which you'd require a Japanese Windows installation otherwise.
As someone who owns a Luma CFW 3DS and used to stream the 3DS over WiFi its awesome to see how Nintendo did it themselfes. Most of this stuff (systems/software) looks just like a hacked 3DS. I remember bricking my (if i remember correctly) SysNand before and was so glad that i had a backup. Any problem when using CFW is a nightmare lmao. Without a good guide i would have never been able to set up CFW/Luma its crazy how much work, testing and knowledge is needed for stuff like that.
The first PCB has more RAM because its doing video scaling, composite and the DVI out. It needs a framebuffer. The second board with actual Nintendo silicon has another FPGA, probably to use its LVDS drivers to drive the longer cables to the controller.
Linus y'all should make a series where you guys get these console dev kits or dev consoles to show them off You guys did the XBox, PS3 and now the 3DS. More would be amazing
@Toma it isn't but they have a large community and people won't mind sending their consoles or dev kits to be features, also it's LMG, they a buncha madlads who'll put off anything that's tech nerdy or tech cool
he said at the start he is always wanting to review this things. it's just that they are so rare that it's hard to get ahold of them. even with his massive community it's rare to get even get a couple, even less that would be OK with him disassembling it
Awesome video! I will say though the controller for the dev kit isn't based off the Wii classic Controller, it's the Classic Controller Pro. It was released alongside Goldeye on the wii, and featured better button placement for the shoulder and triggers, and actual handles.
The smaller board with the DIMM RAM is most likely a cartridge emulator (which afaik, is a possibility) so that you don't have to keep burning your test game to a cartridge. The middle board with the Nintendo ARM chip is the "main" board that has the same SoC as your normal 3ds, and the initial board you saw probably handles all the different capture modes for the different outputs and whatnot
I've used this system to develop some small 3DS games, you could upload games using the debug connection and run it on the device. You didn't need to put it on a dev game card. The only reason for me to use that game card slot was to actually write the ROM to the game card so it could be used on a Test Kit, which was an actual 3DS with test firmware installed, so it could run those dev cartridges.
The Wii controller i believe is the Classic Pro Controller Nintendo had released with the Wii (after the normal Classic Controller (CC from hereon) that plugged into the Wiimote, they had originally released an ergonomic handle that clipped into the original CC; they later redesigned the CC to integrate the handles into the moulding of the shell itself)
Y'all should have seen the earlier Dev/Test kits... Imagine 2 screens on a giant (far from handheld) motherboard that you had to try to angle to make the 3D effect work in a pre-eye-tracking 3DS. Nausea-inducing, to say the least.
Trust me, a lot of people have been dealing with the nightmare of capturing footage from the 3DS. Well, outside of emulators anyway. I remember Etika having issues with his modded 3DS.
Absolutely loving these deep dives on these dev kits! I really hope that you continue to get some more from other consoles as well! Also: watch out for the Nintendo Hitmen... Your probably on a hit list somewhere now 🤣
I think you could've updated the firmware. The problem was most likely that you weren't connected to the internet. At least, going by the previous shot at 5:25 showing that you didn't have a connection you weren't. Of course, if it's using the same wifi adapter as a regular 3DS, those things aren't the most stable, and I've had to try multiple times to do a firmware update.
I dont know if this is the case for this devkit but usually connecting a devkit to the internet on someplace that nintendo didnt whitelist/expect it to be connected in will get your door busted down by police
The classic controller with handles was an actual product. I actually still have some for the Wii with the Nintendo branding still showing. Though mine were solid white like the Wii remote not two toned like yours.
I love how linus and his team are risking a goddamn lawsuit but at the same time having so much fun and linus's exitement and erraticness has been amazing
The 3DS actually got a firmware update a few weeks ago. But the most recent version of Luma3DS still works on that new firmware. My guess is the update was just preparing devices for the eShop sunsetting.
One of the recent firmwares in the past couple of months was just to fix a phone number as far as I remember. The updates are analyzed by the community.
I've always had a soft spot for the 3DS. Had a childhood OG 3DS. Got a New 3DS XL for homebrew around the beginning of 2021. I love to see that the community is keeping it alive, it really is a charming little system. With that being said, I've had nightmares with NNID and the System Settings music gives me heebie jeebies... I have yet to know what is happening in this video, but the first frame looks very interesting. 5:06 I'm assuming you tried pressing X?
I was kind of surprised Intelligent Systems' name wasn't on the 3DS devkit, but glad to see they're on the DS capture device! Fun fact, they started as a hardware partner for Nintendo, particularly manufacturing devkits and other related hardware/software tools, before they wound up developing games themselves.
19:27 This caught me off guard and gave me a really good laugh. Not surprising either, there can be the strangest conditions/caveats with so many different pieces of software and I love it.
Intelligent Systems is a very long time non-subsidiary company that works exclusively with Nintendo. They actually do a lot of stuff overall, from prototyping to full on game development. They've made a ton of classics like the Paper Mario series, Fire Emblem series, and a lot of the classic small titles Nintendo put out in the 2000's like Tetris Attack, Pushmo, and Advance Wars. They're very similar to HAL Laboratories in this regard, though that company was notable for bringing Sakurai and Iwata directly to Nintendo
Yeah, IS are one of around 6-8 "second-party" developers. Other big names here are Monolith Soft (Xenoblade), SORA Ltd., and of course HAL Laboratory and Game Freak. Game Freak are especially interesting because they were at one point fully third-party and have titles in their catalog that were published for Sony systems!
@@NebulonRanger Nintendo owns Monolith Soft (97% ownership), they are not a 2nd party. They're on the same level as Retro Studios and Next Level Games, along side a couple lesser known studios that makes up Nintendo's puny resume of acquisitions
@@genderender Yeah, that was the one I was less sure of. I do know IS and Game Freak are functionally independent, as Game Freak in particular still inhabit the same office space in Tokyo they've been headquartered at since the 90s and are still making multiplatform games (as of 2019 at least).
The 3DS is the main handheld I played on as a kid (the main home console being the og Wii, I believe we got it before the Wii U released), and it's cool seeing a devkit for it, even if I think I might of watched videos about it before. Also, apparently Linus never got the memo about the Classic Controller Pro existing for the Wii. Edit: It’s also a little interesting and weird to see a FPGA used, but I guess it makes sense for a devkit. I guess I just never really thought about it before. Edit 2: I suppose it is also possible that the Nintendo branded chip may be the SOC for the DS, as I believe the 3DS has a separate SOC inside for the DS, but I don't remember for sure. Obviously I don't know that that's the case, that's just my somewhat educated guess.
Interesting to see that one of the boards uses a SuperH/SH-4 CPU. It's one of those weird RISC ISAs that keeps popping up in places, although it's mostly dead now. Apparently there's still a Renesas µC based on SH-2A with availability through 2029, so not completely dead. Most famously, especially considering this is a video about a game console (dev kit), a SH-4 CPU was used in the Dreamcast.
Remember Nintendo Minute ? Those guys streamed 3DS gameplay into screens with a special cable. Maybe the streaming machines still and are sitting somewhere in a basement collecting dust
These devkit videos are so cool. I would love to see a PS2 devkit sometime in the future. There were Debug versions of the PS2, which looked identical to retail except they could run games from any region and had some over-LAN debugging features, the Test PS2s which again are identical to retail except they lack the debugging stuff but will run games from any region, and then there's the big behemoth that is the PS2 TOOL, which is essentially a huge PS2-looking box that houses both PS2 hardware and a Linux PC for development and compiling, each with separate video outputs, at least from what I understand.
4:08 I know all debug/memdump screens look like this but did anyone just find this VERY SIMILAR to the Apple ][ monitor? I mean the even the font seems to match.
7:04 The "Agree Version" thing is referring to the last version of the EULA the user agreed to. Since the Eula can change, and accepting it is a condition of playing online, it would check that that version is the current version, and if not, you'd be prompted to agree to the new one. Say I set up my 3DS when the current revision of the EULA was 2.0, then a few months later, they change it and now it's on version 3.0. The next time I go to play online, the server will see my 3DS reporting that I agreed to an outdated version, and I'll be asked to agree to the current one.
8:21 Uhh, I'm guessing Linus has never heard of the Classic Controller Pro? Which looks just like that, with the handles and full triggers (not just tiny buttons), except in all black.
If I was desiging that unit, top board is just for video out handling, middle board is actual 3DS with the actual silicon, bottom board are for debug info JTAG, TRACE, SWD, and running other monitoring stuff
One way is by using a 3rd party porting service. These are studios with devkits who don't develop their own games but instead take contracts from other studios/publishers to port PC games to console. Services like these are actually required for certain game engines like Godot. This is because manufacturers treat console APIs as proprietary (not just the code itself but even the names of function calls) and don't typically allow any references to their APIs to be checked-in to open source game engines. Porting services can get around this by adding calls to the console APIs internally since they have the licenses and devkits to do so. These weird licensing restrictions on game middleware are also part of why some studios can't release multiplayer server code even if they wanted to as doing so might breach a licensing agreement.
8:22 After the Wii Classic Controller, Nintendo released a pro version off it called the Wii Classic Controller Pro which is the same one the 3DS dev kit controller uses. So as Linus said it is a Classic Controller with ergonomic gribs. I got myself a Classic Pro Controller in gold, it looks pretty sexy.
The Wii did have a "pro" style controller that looked very similar to the dev console controller. It was normally gold painted and was only sold for a limited time. That said, yes, the most common controller was the one that looked like an SNES controller.
You should look into emulation software instead. Those can often also increase the resolution of rendering to make it look better than on the console. Of course it might be a bit less fun without the 3D aspect, but 99% of viewers would just watch in 2D anyway.
You gotta remember linus, the DS commonly featured Sideways games where you hold the DS like a book. Games like Brain Age, Guitar hero and a couple others all featured it, thus the inclusion of the vertical video display mode
fun fact for any other machine shop nerds like me; the Altera Cyclone processor is also used on Haas CNC machines (their "NGC" controller introduced in 2016).
Glad to see these dev kits getting some love, rather than sitting in my basement :)

its a mix of both dev builds do use more ram and so do dev tools

8:21 This controller is shaped like a Wii classic controller pro. It was a product you could buy, so it's not unique to the dev controllers.
Linus, that's the Wii Classic Controller Pro which did in fact make it to market :P
also i'm shocked that they didn't irreversibly brick this system in the filming of this video
Well, we didn't see it work after they put it back together again. ;)
The pro classic controller exists, though it does look slightly different than that dev controller Linus is holding.
Just other colours. It's all white instead of black on the back.
Was about to say. Back when Golden Eye came out on the Wii, they released pro controllers in a gold shell. I have 5 of them for dev purposes.
Was about to say, unfortunately, not the first nor likely the last time that Linus forgets stuff exists... :/
Exactly! He was saying he wanted a product so badly, but it already existed💀
Bet you can easily replicate the look of a dev controller by having both black and white pro controllers and swap their shells
9:09 His Canadian really came out in that sentence, and that's how you know his reaction was real lol.
the Wii U actually has a mirrored AC adapter so they were not reusing the same AC/sensor bar parts
Funfact: That "development" controller was actually released to the public as the "wii classic pro controller" It even had some special editions like a golden one from goldeneye 007 and a red one from Xenoblade Chronicles.
I have that golden one.
It's actually Wii Classic Controller Pro
i like how linus finds a strandard wii classic pro controller and hes like "omg this is way better than the original" when the only difference is the coloring, he was confusing the classic with the classic pro
technically the original classic controller had analog shoulder buttons.
@@zero9112 which one? I have both the classic and the classic pro and they are not analog
@@HungryFox02 the L and R buttons on the Classic controller (the one without handles) are analog. You should be able to test the controller using Brawl and lightly press the button to make a thin shield.
@@zero9112 brawl doesn't have light shields. What you're describing isn't possible.
There are a handful of other Wii games that actually do support the original Classic Controller's analog triggers though, such as some of the Need for Speed games
@@kamen226 thanks for the correction
Fun fact: that development Wii Classic Controller with the handles actually made it to retail as the Wii Classic Controller Pro, most prominently marketed alongside the Wii release of the Goldeneye 007 remake.
These dev kit videos are so cool, it's awesome seeing the behind the scenes
The Nintendo 3DS is pretty special to me, since it was my first console. After homebrewing it I also put some of the Dev-Apps on it. Love seeing Linus messing around in these and showing the dev hardware in detail. Great video!
You did WHAT
Instant like. This content is insanely cool, glad to see you guys not ignoring any end of the tech spectrum, 3DS has a lot of memories to me.
Your life must suck
It's very unlikely the FPGAs are to swap out functionality in the main CPU or GPU. They generally aren't very good at stuff like that - they are usually not big or fast enough to do that (there are high end ones that probably could, but you don't want to know the price). They are probably used for things like glue logic or custom functions, perhaps related to debug or video capture, where it didn't make sense to put a whole board full of logic chips. They could also have been used for things like peripheral controllers and the like, perhaps before they had whatever custom silicon would be in the final device.
I would agree. Although the hardware from the 3DS is low end even for the era I doubt that they would just put the CPU in a FPGA. Specially since the 3DS CPU is not a special hardware. Its your run of the mill ARM CPU. A dual core ARM11 with a PICA200 as GPU.
The main difference is that the 3DS also has a ARM9 that controls other stuff (and you can play with both ARM9 and ARM11 at the same time, both can run custom code). Probably the FPGA is there to glue them together.
I think the whole processing unit is spread between all boards, I couldn't see a board with more than one "main" chip and on a retail they are discrete chips.
"Mister" project does exactly that - does hardware emulation of old consoles. It's expensive, but not unbearable so.
@@manoftherainshorts9075 Mister has a Cortex A9 on it and a much newer Cyclone V. Also, until now the limit of Mister is something close to a PSX. A 3DS can emulate a PSX (although slowly) on itself.
Its very hard and costly to put a "modern" architecture CPU running at hundreds if not thousands of megahertz on a FPGA. And ARM CPUs are generic enough to be cheap to purchase instead of trying to build.
Mister try to solve the issue of older more specialized hardware that aren't so generic.
@@manoftherainshorts9075 Quite true. But those are very old CPUs being emulated on modern FPGAs. To explain, the SNES processor might have been a 1um process (can't find exact numbers). The FPGA the Mister uses is 28nm (that's 0.028um). It's not that FPGAs can't emulate CPUs (they certainly can - lookup softcores), but, all other things being equal, an FPGA that can emulate a contemporary CPU will be very expensive, assuming it can do it at all.
Thank you for saying this I was screaming it at our cats through the whole video
The "developer board" is probably an ICE (in circuit emulator), most console development kits have this circuit that sits between the CPU and the rest of the system to allow you to do things such as breaking the execution of the program and reading the CPU registers and the memory of the system etc etc etc..
It's how you can do breakpoints on an external system among other tricks.
I kinda hope game manufacturers enjoy seeing their old devkits get shown in videos like this, imagine developing something like this, and then the public never gets to know about the feat of engineering that it was
That top FPGA board is no doubt the dual video output board. Reproducing strict video signals and timings are exactly what FPGA's were designed to do
That capture USB: I recall that for the Wii dev kit, you had the ability to "fake" high rez when you took a screenshot, the machine would take a ton of screenshots then come up with a high rez composite.
I have a small anxiety attack any time I see Linus holding rare or expensive kit - I know I'm not the only one
at 11:35, he nearly drops the controller, and you can see him reaching to grab it
In his head "I can afford to do this." and then immediately breaks the thing he's carelessly swinging around by the most fragile part of it.
I usually don't mind but when it's other people's priceless gear that he's so obnoxiously waving around...
if you mean the 3ds thats basically just a screen no those arent that fragile... plus it was super light cuse there were no other internals except a little display driver for the screen and the 3ds on its own is very sturdy design. ive dropped mine like a million times and it barely shows a scratch from it @@TheRetroMess
That controller Linus was using actually did make it to market as the Classic Controller Pro. The dev one is a weird mix of parts from the white and black models though.
Something about this video has awakened my nostalgia for when the 3DS was first announced and seemed like a crazy premium product. Thanks!
You need to update to Luma 11.0 since in September there actually was a new firmware update for the 3ds (yeah crazy huh?) I mean there could be a ton of other problems with whatever firmware that 3ds is running, but thats normally what you would need to do with a Luma 3ds to update firmware.
Doubt there's any firmware updates for a dev unit.
@@Sanrasxz The 3DS part of it probably runs retail firmware. The development apps on the 3DS part most likely use connections that are simply severed in a retail product but are connected to the debug board within the dev kit. Alternatively they could use special codes over an otherwise used connection, either way the actual 3DS part is probably the same as a retail system.
@@Sanrasxz lol no way it’s you, I see you all the time in the flashcarts subreddit
What kind of absolute madman would let Linus play with his one of a kind dev kit? Dude literally drops everything he touches!
The way he shakes around the open shell made me cringe. That hinge is not hard to damage..
they arent one of a kind lol you used to be able to buy them. yes literally anyone could buy one
Damn this man is risking a lawsuit from nintendo for everyones entertainment, what a legend
While Nintendo is way bigger than LMG, LMG probably has better than average lawyers on retainer so while they certainly exhibit a bit of hubris with these videos, it's no doubt a move they make after careful calculations.
A lawsuit Nintendo won't win since they're not actually pirating and using laws that were set a long time ago about VCR and cassette tape recording where we the consumer was given the "Right to copy as a backup"
The only grey area are the dedicated emulation devices that don't reverse engineer the console software, but rather run the Nintendo firmware in a virtualized environment.
@@bustex1 better than *average*. LRN2READ
Here before it blows up
@@bustex1 He said better than average, not better than Nintendo. Good enough to tell them what they *can* and *can't* do/say.
19:32 someone tell Linus there is a tool called "Locale Emulator" and during XP days you could install Microsoft's own local emulation layer "App Locale" as well. NtLea was another option. All three could co-exist (each worked slightly different and thus the applications would run with one tool, but not with the other), but mainly "Locale Emulator" survived to this day.These tools work with like, I'd say, 97% of the software which require Asian locale settings. At the very least, I only have like a handful of games or software which do not run with the locale emulation. I have likely used it on a multiple of hundred games so far, for which you'd require a Japanese Windows installation otherwise.
As someone who owns a Luma CFW 3DS and used to stream the 3DS over WiFi its awesome to see how Nintendo did it themselfes.
Most of this stuff (systems/software) looks just like a hacked 3DS.
I remember bricking my (if i remember correctly) SysNand before and was so glad that i had a backup.
Any problem when using CFW is a nightmare lmao.
Without a good guide i would have never been able to set up CFW/Luma its crazy how much work, testing and knowledge is needed for stuff like that.
This is very cool, would love to see more Dev Kit videos from LTT. Much love from BC.
The first PCB has more RAM because its doing video scaling, composite and the DVI out. It needs a framebuffer. The second board with actual Nintendo silicon has another FPGA, probably to use its LVDS drivers to drive the longer cables to the controller.
8:12 this did release as the "classic controller pro"
love that they made the CTR look so similar to the Nitro (DS dev kit) despite being made by a different hardware manufacturer
9:14 if you put that on a 3D TV you might be able to see it as the player will see on their 3DS...
11:38
"and the easiest way to get it open seems to be..."
drops it on the floor
Linus y'all should make a series where you guys get these console dev kits or dev consoles to show them off
You guys did the XBox, PS3 and now the 3DS. More would be amazing
@Toma it isn't but they have a large community and people won't mind sending their consoles or dev kits to be features, also it's LMG, they a buncha madlads who'll put off anything that's tech nerdy or tech cool
Im pretty sure ltt is already doing that. As evidenced by this video, and several previous like it
he said at the start he is always wanting to review this things. it's just that they are so rare that it's hard to get ahold of them. even with his massive community it's rare to get even get a couple, even less that would be OK with him disassembling it
I love seeing these dev kits.
same
Linus is his name, but spiting Nintendo is his game 🤙

I love how Linus didn’t know about the Classic Controller Pro.
I would love to see the "new" 3ds version. Cool video as always guys!
4:08 that is such a familiar screen to me that i immediately felt the secondhand frustration of my 3ds crashing
Awesome video! I will say though the controller for the dev kit isn't based off the Wii classic Controller, it's the Classic Controller Pro. It was released alongside Goldeye on the wii, and featured better button placement for the shoulder and triggers, and actual handles.
Retail also got the Classic Controllers with grips, but they where mostly black (white once exist, pretty sure they are more common in NTSC)
yeah they're the pro controller. I used to have a black one and a gold one (the goldeneye edition)
@@kasuraga where sold as classic controllers here
@@vinstaal0 ah. everywhere i know it was sold as the Wii Classic Pro controller.
The smaller board with the DIMM RAM is most likely a cartridge emulator (which afaik, is a possibility) so that you don't have to keep burning your test game to a cartridge. The middle board with the Nintendo ARM chip is the "main" board that has the same SoC as your normal 3ds, and the initial board you saw probably handles all the different capture modes for the different outputs and whatnot
I've used this system to develop some small 3DS games, you could upload games using the debug connection and run it on the device. You didn't need to put it on a dev game card. The only reason for me to use that game card slot was to actually write the ROM to the game card so it could be used on a Test Kit, which was an actual 3DS with test firmware installed, so it could run those dev cartridges.
Small correction: the 3ds did NOT have bluetooth, the antenna is more likely WiFi+NFC
Correct. I wish it had bluetooth.
@@hicknopunk you could wire up a bluetooth audio transmitter to the headphone jack but yeah something like the psp/psvita/switch have would be great
@@iknowdawae893 i thought of that too, but I really want bluetooth to use a ps4 controller to not wear out my buttons.
@@hicknopunk A software modded 3ds can use an external controller.
@@ImJustPassingThrough i remember using the xbox one controller on 3ds but you needed a pc
The Wii controller i believe is the Classic Pro Controller Nintendo had released with the Wii (after the normal Classic Controller (CC from hereon) that plugged into the Wiimote, they had originally released an ergonomic handle that clipped into the original CC; they later redesigned the CC to integrate the handles into the moulding of the shell itself)
Y'all should have seen the earlier Dev/Test kits... Imagine 2 screens on a giant (far from handheld) motherboard that you had to try to angle to make the 3D effect work in a pre-eye-tracking 3DS. Nausea-inducing, to say the least.
Trust me, a lot of people have been dealing with the nightmare of capturing footage from the 3DS. Well, outside of emulators anyway. I remember Etika having issues with his modded 3DS.
Swimling you're crazy sending this to Linus who has a tendency to drop things. Linus the way you held that 3ds by the cord made me scream internally 🤣
I jokingly told them not to break it… if you were screaming internally, imagine how I felt lol
Oh I can here it all right
3ds was goated man low key
Considering the sales, it's not an unpopular opinion at all.
*trash
Low key? It's the Handheld GOAT period.
@@herooftime9921 yep. People who think the 3DS was a good console are human excrement. Thing had bad games. Vita was better too.
One of the best consoles
Absolutely loving these deep dives on these dev kits! I really hope that you continue to get some more from other consoles as well! Also: watch out for the Nintendo Hitmen... Your probably on a hit list somewhere now 🤣
I think you could've updated the firmware. The problem was most likely that you weren't connected to the internet. At least, going by the previous shot at 5:25 showing that you didn't have a connection you weren't. Of course, if it's using the same wifi adapter as a regular 3DS, those things aren't the most stable, and I've had to try multiple times to do a firmware update.
I dont know if this is the case for this devkit but usually connecting a devkit to the internet on someplace that nintendo didnt whitelist/expect it to be connected in will get your door busted down by police
The classic controller with handles was an actual product. I actually still have some for the Wii with the Nintendo branding still showing. Though mine were solid white like the Wii remote not two toned like yours.
I have a Wii classic controller that's a 'pro' version, and it has handles. Linus just doesn't use Google.
Next morning, the Nintendo Ninjas will be paying Linus a visit...
Nice knowing ya, Linus!

I love these dev kit videos, they're some of the coolest things on this channel
The 3DS actually got a firmware update a few weeks ago. But the most recent version of Luma3DS still works on that new firmware. My guess is the update was just preparing devices for the eShop sunsetting.
One of the recent firmwares in the past couple of months was just to fix a phone number as far as I remember. The updates are analyzed by the community.
@@ImJustPassingThrough interesting!
*_That dev kit would be a 3DS fanatic's dream come true._*

@@tylertr Nice.
I've always had a soft spot for the 3DS.
Had a childhood OG 3DS. Got a New 3DS XL for homebrew around the beginning of 2021.
I love to see that the community is keeping it alive, it really is a charming little system.
With that being said, I've had nightmares with NNID and the System Settings music gives me heebie jeebies...
I have yet to know what is happening in this video, but the first frame looks very interesting.
5:06 I'm assuming you tried pressing X?
I was kind of surprised Intelligent Systems' name wasn't on the 3DS devkit, but glad to see they're on the DS capture device! Fun fact, they started as a hardware partner for Nintendo, particularly manufacturing devkits and other related hardware/software tools, before they wound up developing games themselves.
19:27 This caught me off guard and gave me a really good laugh. Not surprising either, there can be the strangest conditions/caveats with so many different pieces of software and I love it.
Intelligent Systems is a very long time non-subsidiary company that works exclusively with Nintendo. They actually do a lot of stuff overall, from prototyping to full on game development. They've made a ton of classics like the Paper Mario series, Fire Emblem series, and a lot of the classic small titles Nintendo put out in the 2000's like Tetris Attack, Pushmo, and Advance Wars. They're very similar to HAL Laboratories in this regard, though that company was notable for bringing Sakurai and Iwata directly to Nintendo
Yeah, IS are one of around 6-8 "second-party" developers. Other big names here are Monolith Soft (Xenoblade), SORA Ltd., and of course HAL Laboratory and Game Freak.
Game Freak are especially interesting because they were at one point fully third-party and have titles in their catalog that were published for Sony systems!
@@NebulonRanger Nintendo owns Monolith Soft (97% ownership), they are not a 2nd party. They're on the same level as Retro Studios and Next Level Games, along side a couple lesser known studios that makes up Nintendo's puny resume of acquisitions
@@genderender Yeah, that was the one I was less sure of. I do know IS and Game Freak are functionally independent, as Game Freak in particular still inhabit the same office space in Tokyo they've been headquartered at since the 90s and are still making multiplatform games (as of 2019 at least).
man, calling Advance Wars a "small title" is kinda BS
The 3DS is the main handheld I played on as a kid (the main home console being the og Wii, I believe we got it before the Wii U released), and it's cool seeing a devkit for it, even if I think I might of watched videos about it before. Also, apparently Linus never got the memo about the Classic Controller Pro existing for the Wii.
Edit: It’s also a little interesting and weird to see a FPGA used, but I guess it makes sense for a devkit. I guess I just never really thought about it before.
Edit 2: I suppose it is also possible that the Nintendo branded chip may be the SOC for the DS, as I believe the 3DS has a separate SOC inside for the DS, but I don't remember for sure. Obviously I don't know that that's the case, that's just my somewhat educated guess.
As a kid?!
@@zach.0 At the time the 3ds released in 2011, I was about 7.
bruh thats wild i turned 15 then lol@@jnut1246
Interesting to see that one of the boards uses a SuperH/SH-4 CPU. It's one of those weird RISC ISAs that keeps popping up in places, although it's mostly dead now. Apparently there's still a Renesas µC based on SH-2A with availability through 2029, so not completely dead.
Most famously, especially considering this is a video about a game console (dev kit), a SH-4 CPU was used in the Dreamcast.
Remember Nintendo Minute ? Those guys streamed 3DS gameplay into screens with a special cable. Maybe the streaming machines still and are sitting somewhere in a basement collecting dust
These devkit videos are so cool. I would love to see a PS2 devkit sometime in the future. There were Debug versions of the PS2, which looked identical to retail except they could run games from any region and had some over-LAN debugging features, the Test PS2s which again are identical to retail except they lack the debugging stuff but will run games from any region, and then there's the big behemoth that is the PS2 TOOL, which is essentially a huge PS2-looking box that houses both PS2 hardware and a Linux PC for development and compiling, each with separate video outputs, at least from what I understand.
Dev Kits are always so crazy
This would actually be pretty fun to play on a 3d tv/projector
I'm disappointed they didn't test it out on an actual 3D TV.
Linus lately been pushing for that Nintendo cease and desist 💀💀
Honestly, this kind of hardware is unlikely to get a cease and desist.
4:08 I know all debug/memdump screens look like this but did anyone just find this VERY SIMILAR to the Apple ][ monitor? I mean the even the font seems to match.
03:51 he almost poked that TV with the LTT screwdriver in his back pocket 😳
Alright, whose bright idea was it to let Linus Drops Tips to hold an extremely rare machine?
Especially when he was holding the boards 💀💀💀
THE WAY HE WAS SWINGING THE 3DS AROUND BY THE CORD BRO NOOOOO
I don’t know about Nintendo but… I want it
Someone archive this video before Nintendo sends a Cease and Desist
7:04 The "Agree Version" thing is referring to the last version of the EULA the user agreed to. Since the Eula can change, and accepting it is a condition of playing online, it would check that that version is the current version, and if not, you'd be prompted to agree to the new one. Say I set up my 3DS when the current revision of the EULA was 2.0, then a few months later, they change it and now it's on version 3.0. The next time I go to play online, the server will see my 3DS reporting that I agreed to an outdated version, and I'll be asked to agree to the current one.

Great review, good job 👍
The video is 5 minutes old you didn't even watch all of it 💀
always a great day when linus uploads!
Bot reply?
Nintendo devkits are the epitome of "well, it works..."
8:21 Uhh, I'm guessing Linus has never heard of the Classic Controller Pro? Which looks just like that, with the handles and full triggers (not just tiny buttons), except in all black.
If I was desiging that unit, top board is just for video out handling, middle board is actual 3DS with the actual silicon, bottom board are for debug info JTAG, TRACE, SWD, and running other monitoring stuff
I struggle to understand how small developers and indie devs have been able to develop their games with entry requirements this high and expensive
One way is by using a 3rd party porting service. These are studios with devkits who don't develop their own games but instead take contracts from other studios/publishers to port PC games to console.
Services like these are actually required for certain game engines like Godot. This is because manufacturers treat console APIs as proprietary (not just the code itself but even the names of function calls) and don't typically allow any references to their APIs to be checked-in to open source game engines. Porting services can get around this by adding calls to the console APIs internally since they have the licenses and devkits to do so.
These weird licensing restrictions on game middleware are also part of why some studios can't release multiplayer server code even if they wanted to as doing so might breach a licensing agreement.
Who in their right mind would trust Linus to told something like this...
bro has modded 3ds dev kit wtf
8:22 After the Wii Classic Controller, Nintendo released a pro version off it called the Wii Classic Controller Pro which is the same one the 3DS dev kit controller uses. So as Linus said it is a Classic Controller with ergonomic gribs. I got myself a Classic Pro Controller in gold, it looks pretty sexy.
The Wii did have a "pro" style controller that looked very similar to the dev console controller. It was normally gold painted and was only sold for a limited time. That said, yes, the most common controller was the one that looked like an SNES controller.
I hope someone can reverse engineer this and make a device like this, it would be so useful to have this for game development and streaming
Why? No one is developing for the 3ds anymore.
You should look into emulation software instead. Those can often also increase the resolution of rendering to make it look better than on the console. Of course it might be a bit less fun without the 3D aspect, but 99% of viewers would just watch in 2D anyway.
I. WANT THIS. SO. BAD.
Same, as a DS/3DS modder
Let's see how long time it takes until Nintendo takes this down 😅
You gotta remember linus, the DS commonly featured Sideways games where you hold the DS like a book.
Games like Brain Age, Guitar hero and a couple others all featured it, thus the inclusion of the vertical video display mode
fun fact for any other machine shop nerds like me; the Altera Cyclone processor is also used on Haas CNC machines (their "NGC" controller introduced in 2016).
