Since this keeps being asked:
The RAM add-on added around 1-2 FPS in the final result.
Adding more RAM to a system that already has enough usually does not help. The only reason it helped here is the specifics of the RAMBUS and the manual RAM aligning..
@@Yveldi upload more graphics card for further boost
you sir are a god could you also re-write ocarina of time to allow an open source modding archtype like skyrim or fallout has? would be an insane community service tool you could expand your patreon as well. no biggy right?! xD who knows maybe you like the idea whatever you do looking at this project it's bound for succes great job my man!
Can you please optimize Ocarina of time too?
But you said in the video it isn't doable without the RAM expansion. So, for most of the N64 lifespan, it was an impossible feature.
I have to admit the only thing I was impressed about was how you tried to take out all the bottlenecks between the CPU, RAM & RCP. And you took things to the next level by asking this project: 'is this all I am ? Am I using the hardware to its fullest capacity & capability. Is the software doing this as well ? Can this project work on every level ?' I have actually made this argument to gamers about current games and most people never bother a reply despite the fact I'm not after an argument but just a discussion in computer philosophy. Because I'm good with refining renovation projects until they reach a level of all round perfection. But I am not a perfectionist. Don't you think the engineers who built the pyramids were thinking along the same lines as us ? I enjoyed your video. I think your the first to have done something like this on TH-cam ???
he finally did it, he went insane.
The moment we all anticipated
This is the one where he's finally lost it.
What if he went so insane that he went full circle and returned to normal as an ascended being?
we have reached the endgame of sm64 modding
I'm just glad I was here to see it
This shows what “standing on the shoulders of giants.” Dozens of people barely pushed out M64 in the 90s. One man was able to triple the performance, but because of what know;edge has been developed and shared in the past 25 years. Amazing work, sir!

@Walid Fakhfakh Mario 64 is a really important game historically, it really figured out 3D camera control and controls in general, it's easy to take for granted now but a lot if early 3d games were fixed camera and had 2.5d controls or tank controls.

Reading and rewriting an entire game's source code just so your mod runs faster is such a power move. Vroom vroom.
a powerer move would be to make a shitty mod that slows down the game, then optimize the game but not the mod, so it runs at 100%

how about, a week after SNES launch of super mario world, doing a credits warp in front of the devs
@@mmoncure11 *day before launch
Some of these optimisations would seem like sorcery to the best devs in the world haha
"You can either learn these or go outside and touch grass." - The duality of programming.
This is pure backend refactoring bliss! Writing good and optimized code is an art and should be valued more by all development companies. This is why I think all games after some years of its sales end should become open-source.
Daikatana is a good example of this. Poorly received at the time, it was later open sourced and mods and bug fixes created a much improved game.
who knows, maybe even all software..
The sad reality is that development and production companies value money first and foremost, which means they are often incentivized to sell good enough software rather than great software. The N64's launch was delayed to make SM64 good enough. It went on to sell millions of copies and become one of the most beloved games of the late 90s. If an unstable 20FPS frame rate was good enough for that, why would they delay further?
That said, death of author + 70 years is an insane copyright duration. The original maximum duration in the US was 28 years. 28 years after SM64's release is 2024. Under those terms, Nintendo would "only" have had time to sell the original release, the vibration support rerelease, the DS rerelease, the Wii Virtual Console rerelease, the Super Mario All-Stars 3D rerelease, and the Switch Online rerelease before the code went public domain.
Oh god just imagine if we lived in that world . So many more indie games
I’d start with parasite eves code base and use that as a jumping off point for my game
Good code, fast code, easy to read/write code... Pick any 2. Engineering is all about tradeoffs and you need to understand the requirements. It's possible that if Nintendo wrote such super optimized code back in the day they would have missed a market window and it would never get released. Instead, it was "good enough" and was hugely successful for a flagship game.
Two great quotes that will stick with me from this video:
"You either get to know about these things, or you get to go out and touch grass every once in a while. It's a strict either or, you can't have both."
"RAMbus goes vroom vroom."
aaaahh, grass.... I was convinced he said "You either get to know about these things, or you get to go out and touch GIRLS every once in a while. It's a strict either or, you can't have both." It made me giggle
Came to comment exactly that first quote. I'm 100% stealing that and planning to use it absolutely as soon as I can shoehorn it into a conversation.
I want to touch grass…
@@kaneCVR Wait, but I don't understand all those stuff and don't have a chance to go out and touch....
that earned a sub from me, not just the words, but I felt it was a genuine statement.
If this was possible 20+ years ago, imagine how unoptimized games are today.
*laughs in halo infinite*
Don't have to imagine, lol.
the sad thing about modern game optimisation is instead of utilizing new hardware to actually improve visuals AND framerates and resolutions, they use it as an excuse to not optimise at all because "the newest tech can handle it anyway"
@@lazulazu2467 Pretty much this. Used to allocate time in my projects to optimise, now I dont bother so much. Sure my methods have improved, but hardware patches over the cracks nowadays.
Its a shame, hardware improvements allowed software developers like myself to get lazy. Unless your working with 3D gfx, why bother. If you do work with 3d graphics call it a game for the future and move on.
Real shame. I still remember marvelling at how they managed to fit some of those Pokemon games on those GB carts way back when. Those optimisations wouldnt happen now, youd just be directed to download a patch on launch.
Imagine a very old ring
This is INSANE. The map you demonstrated on looks like it could have been a GameCube launch title, and yet somehow runs on a real N64.
I would say Dreamcast

Kaze: Yeah I optimized the source code for Mario 64, took a couple weeks.
Nintendo: Source code?
Kaze is just the best. My favorite thing is that he doesn’t give the original developers any grief. There was just not enough knowledge available to have done all of this for them. Really honorable thing to mention. Thanks Kaze.
Same. :)
If they’re not confident enough to ship the finished game using an optimized build that wouldn’t introduce any bugs under the time constraints they had, it’s EARLY DAYS. Miracle that this game works as well as it does.
Developer solidarity
Also gotta keep in mind he's doing this with no constraints. He doesn't have to meet a deadline, stay within a budget (no need for expensive SGI machines when we have Blender), worry about whether future console revisions will break his clever hacks... No limits on ROM size, twice as much RAM, and way more advanced tools...
@@johnsimon8457 You need to realize that this was during the 1990s. The game wasn't an early build. The game wasn't in "early days". The game worked fine. But, because of the lack of technology, there were bugs. Simple as that.
Kaze: "Hey Nintendo, I literally made your game perfect."
Nintendo probably: "Die."
Capitalism in a nutshell
"if you just program well, you don't need to prevent crashes" is an absolutely insane (but not entirely wrong) thing to say and I absolutely love it. I can't get enough of your channel :D
As an gamer/engineer who originally learned/programmed in C++, I appreciate this video, some of the code improvements you found were super interesting, thanks for this!

“if you just program well, you don’t need to prevent crashes”
what a chad
I've been coding professionally for over 20 years, that is some super impressive work and entertaining with it. Code optimisation is one of my favourite tasks.
You can't blame the devs all that much either, since Super Mario 64 was a launch title. They only had so much time between when the system was available to begin developing for and when the console had to be released.
3D games were basically brand new so it's a very commendable effort.
I'd say "Nintendo, hire this man" but honestly Kaze just hired himself at this point
Nintendo fans: "Hire this man!"
Nintendo lawyers: "Take down all his videos, and threaten to sue him!"
Nintendo doesn't deserve him!
If it were Sega, sure. But his hands would be tied. Better to keep this as a "patch" to the original ROM, which is probably going to be a complete replacement of every byte, but you know... can't go distributing whole ROMs without summoning the thunder.
@@nickwallette6201 The secret is, do not make it work without an original copy, so, it's a mod

As someone with a master's degree in computer science I can confirm: This is wizardry.
You need a masters degree in kaze science
As someone who reads TH-cam comment: Okay
It's: FIXING LAZY JPN GAME DEV
As someone who watched this video: does a master's degree in computer science not teach you how to clean up superfluous code for optimal performance? John Carmack's been showing the world how to do that since the 90s - he got raycasting* working on literally anything and got Quake to run in full 3D on pre-Pentium PCs with no dedicated graphical hardware :/
*don't make my dumbass mistake of confusing raycasting with raytracing or you're gonna confuse everybody :P
@@reloadpsi University teaches you the value of clean, maintainable (i.e. readable) code that is robust against any kind of problem. That's much more important than maximizing performance by throwing all of that out of the window. With today's machines performance isn't that much of a priority anymore. ;) (NOTE: I'm talking about games here, not general software)
Also, when it comes to efficiency, there are some very different fields in computer science: (A) Optimizing algorithms, i.e. the general (macro) structure of the program (which is much more important) and (B) optimizing code for hardware usage (micro level), where you reduce the amount of calls / memory access, etc. So (B) means "what can we speed up, when the algorithm stays the same". And Kaze is doing (B) *hardcore style.*
I like how everything no matter how complicated it got it always ended with the RAMbus going vroom vroom
Hell yeah dude. I didn't even know this was more than an amazing fan feat until I saw who put out the video. The man himself. Holy Crap. Great sense of humor, I've only ever seen the finished SM64 content, never heard the man speak. I had a good time watching this.
As an idiot, I appreciated seeing it appear so I could clap my hands together and laugh for a moment in between feeling confused.

What this man did was more equivalent of tweaking every single thing on the car so that it runs as efficiently as possible with the least possible amount of upgrades.
Y'know, when I heard the source code was decompiled, I noticed Kaze went kinda quiet. Now I know that he used that time to REWRITE THE ENTIRETY OF SM64 TO A STATE THAT MAKES SHIGERU BLUSH!.
It's funny that so much time was spent decompiling the game and then straight after the release we got the Nintendo giga leak which had the source code for it anyway.
@@Agret from what I heard, it was only some of the source code, basically what was necessary for IQue to make their own version of Mario 64, so the entire source code wasn't leaked as of now

this is amazing. love optimization deep dives like this. I miss the days when we were that close to the hardware.. .Rock on!!
This shows the understanding of the hardware that homebrew devs have gained vs devs from back in the day,. This also shows what dev can do when they're not rushed for time.
Also a good example of "too many cooks in the kitchen"
"Two developers can do the job of one developer in twice the time."

You are truly a gifted man, well done. Your work is simply amazing, SUBSCRIBED
The rolled loops thing is funny. Obviously unrolled loops make the code much less maintainable, less readable, less terse, and more error prone. But back then programmers used to unroll loops as an optimization to save some CPU cycles (as the for loop part of the code does not need to run again and again ). But now we are seeing that rolling them actually improves performance. What a perfect cautionary tale about premature optimization, and also optimizing without profiling.
we used to do this on C64 as well to get more cycles :-)
*Programmers* should not be the ones unrolling loops. Programmers should be writing code that allows the *compiler* to unroll the loop *if the compiler determines that an unrolled loop would improve efficiency*. This requires an intimate understanding of the hardware that the code is running on. If you have a shared bus and your instructions are cached, then yes, smaller code size optimization (i.e. rolled loops) will win over "faster" code speed optimization. That is unlikely to be the case for an in-order processor with no pipelining or cache.
That said, you *do* need a good compiler and that compiler *does* need good knowledge of the hardware, or this all goes out the window. I've developed some code for the PIC and their C compiler is outright horrific. I can't tell you how many times I've had to twist myself into a pretzel to get the compiler to generate good code, and sometimes I just need to write it in assembly because the compiler is too stupid. And their compiler is made by the the same company that makes the microcontrollers!

"If I had more time, I would have written a shorter letter."
I think this quote works well here. It takes time and skill to be able to optimize. The more optimization done the more astounding really. Sadly a lot of companies don't optimize as 'todays hardware can easily handle it." Which is why we get games that breach 100GB when they honestly shouldn't.
The size of the game is generally due to assets, not unoptimized code.
I work as a consultant optimizing games. It very often comes down to fact that you have a feature/performance trade-off. Meaning, you COULD spend time speeding up your game, but it would mean delaying feature X or tool Y by N weeks. Often, having something that works is much more valuable to your development process than having something that is fast, because things that WORK unblock other tasks, while things that are FASTER rarely unblock anything unless we are looking at issues that require 100x speedups. This is true for small companies - larger companies should have more dedicated people with strong profiling skills, but small companies are often too busy to even open a profiler.
@@levonschaftin3676 well, egg on my face and shows what I know about game coding.

At this point Kaze is somehow gonna turn SM64 into an early GameCube game and that's just awesome.
What's kinda funny is I've thought about actually porting some N64 games to GameCube just so mods can take advantage of the extra resources and better emulation.
@@renakunisaki is that even possible? Because if so…

@@renakunisaki I suppose it would need a full rewrite though - IIRC the N64 doesn't even use the same processor as the GC, let alone a similar architecture for rendering

7:45 "Usually if you did this, you would get fired from your job"
Completely understandable, won't even lie. I can't imagine even the most well-equipped programmer understanding something as insane as the Q_rsqrt function (for an example of course), especially during that time period. Ahh, classic C black magic.
A lot of this stuff would get you fired, the loop unrolling also comes to mind. I hope Kaze points out that although he's optimizing everything, optimization is only one facet of good programming and generally not the most important one in a professional setting like readability.
You might not be fired if you left comments explaining exactly why you're doing these silly things, and tests showing that they are actually helping.
@@LizardLeliel it's all about context. He's programming for a never changing target (dead platform), with so much hindsight. There's no need to worry about mantainability because the game (engine) is forever done, etc. I'm sure if this was a an "actual job" he wouldn't be fired, he's worked according to requirements.
@@Radgerayden-ist I'm not saying he's doing bad for focusing on optimization here - he's the only programmer involved in this project. I'm just genuinely afraid new programmers may get the wrong idea that the standard of good code is just optimization.
@@LizardLeliel as someone who constantly messes up in Scratch, I can confirm readability is key to make a good game, even there you may get disoriented if you're being reckless with the block programming, let alone other guys looking at your code.

I think this has become my favorite video on youtube. Im currently studying for a software engeineering degree and I love covering memory optimisation in programs, so this was a great watch! Also sm 64 was one of the first games I played so bonus points for that
Awesome video, i really love how in depth you went!
I am highly interested seeing a definitive edition of the split-screen multiplayer using these optimizations. I would like to be able play the multiplayer smoothly on real N64 hardware.
I also find you videos regarding the work performed in order to make these optimizations fascinating.
it would be really cool to hear what the original programmers think about this.
I'd be very happy to see support or honest reactions from devs instead of "don't touch our IP"

This level of optimization is absolutely mind blowing. If I were Shigeru Miyamoto, I would be so proud to see a passionate developer improving this game to this point so many years later. It proves how deeply his creations impacted our generation.
Well said.

It's nice knowing that intelligent people are still online
Shiggy hates anyone that takes something he had a hand in and "makes it better" in any way, so this would likely be seen as an affront to his work. Just as an example, he dislikes the DKC SNES titles because they're (literally) "Not his Donkey Kong", and tried to 1-up them with 'Returns' on the Wii (and arguably failed because the shoehorned motion controls directly conflict with the base gameplay the series is built on).

The unrolled loops are funny from a modern perspective - I'd write them as loops and then unroll later if i needed performance, even if compilers couldn't do it for me - but considering these devs were coming from the SNES? Makes total sense that they would just assume it's the right thing to do.
I'd love to see a rom patch for these improvements. It would be nice to see how much better M64 would run.

I remember playing N64 games as a kid and looking at the skyboxes thinking "Why can't I go there? Why didn't they make it? It would be so much fun." This is exactly what it feels like to see mods for this game all these years later. Thanks for making this! (to everyone involved)

What we actually get : We lost the source code...so we just scrapped something similar together and hope y'all don't notice
@@lilaa3 Nintendo is an awful company from a consumer level and I'll actually never buy another product from them as long as I live. Even if I may want to.
Or they take the source code from the worst versions of the game.
Silent hill......
@@lilaa3 Yeah it's more like "We've already got a working emulator for these games, it'd be faster to just use that, than spend the dev time to make a proper port" than anything about losing the source
Still, there's so many things they could've fixed and just decided not to. Didn't even take the time to change the goddamn button textures. I don't remember my switch having a bean shaped grey X button, or a bright red B. One of the only changes I can recall that made it into the initial release was mario sunshine's camera controls being inverted to align with the other games. Which made it feel completely wrong to anyone that's played sunshine before. The only major change made the game worse for a lot of players
That's what happened with FF8 remaster
As a programmer and engineer I can say that this is a MAJOR achievement and a LOT of work. I can't congratulate him enough. Heck, the fluid framerate even looks like Super Mario Galaxy or Super Mario Odyssey. I just disagree when it was said that "the Nintendo programmers were not familiar with C, because it was a new language back then". C originated in the early 70s and was and is a well-known language. However, what is certain is that many 90s game programmers were making the transition from assembly to C / C++ code, I think that's what was implied in the video. It's a minor detail, like a 0.001% of what's in the video. KUDOS
Oh ok, I was wondering how C was a new language being already at that time 20 years old or so... It took that long to begin transition ? was it due to compiler refinements ? or just inertia ?
@@nlight8769 high level languages did not compile efficiently enough to be usable on older consoles, N64 was one of the first where the hardware power was capable of handling the unoptimizations to a degree
@@digiquo8143 Thanks :)
Just one last question, what was the language used for the previous gen (SNES, MegaDrive) ?
@@nlight8769 From what I've read, most were built with assembly. aka, assigning the hex values to their location in memory manually.
@@digiquo8143 Wow, asm is pretty hardcore for anything elaborate. Respect to the designers and programers from that era.
Thanks :)
Excellent work. I wish I could do something like this.
Excellent work, truly, I wish I had this much passion and work ethic.
Mad props to you sir. Excellent work. Subbed
I didn’t believe it’s possible at first but the vroom vroom joke really does get funnier the more it’s repeated
The Family Guy effect
Repetition legizimizes
@@Sebb_Music Repetition legitimizes
@@otesunki Repetition legitimizes.
Rule of 3 be damned
Its insane seeing how pretty this mod looks after so many optimizations. I never knew N64 was capable of those graphics
Amazing computer science work brother. Actually inspiring
I hope that GDQ allows this game to be played and have its own category, calling the game "Super Mario 64 plus" or "Enhanced SM64" or something, so we can watch speedrunners tear into it. Very exciting.
It all depends on whether there's a community for it, probably; I remember a few (smw) rom hacks being played at gdq
Why not call this Expansion Pak support version the Kakuchou Edition (拡張 meaning expansion), like the Rumble Pak support version is called Shindou Edition (振動 meaning rumble)?
Super Mario 64 plus exists tho, it's a version of the PC port with a lot of features
@@cmyk8964 I personally want it to be called the "Haha, RAMbus goes Vroom Vroom" - Edition
Any plans on making a patch for the base game where it runs as fast and optimized as possible?
Yeah, I'd absolutely love to see this!
It would be interested to see this implemented in libsm64 so we can see Mario run in 60 fps inside other games :o
I also want this on super mario 64 land
PLEASE
Seconded! I got an Everdrive64 a few months back and would love to play it at 60 fps on real hardware.
Really cool work, so were your optimizations possible back when the game was being made but the knowledge just wasn’t there at the time? Really cool video, either way. Thanks for sharing!
Amazing improvements! Hats off.
Love the way you document the process, glad to be along for the journey!
Pretty cool to see the king of syntax in the wild.
@@casperdewith why yall love super mario 64? n64 is too old and thr game looks bad anyway
One interesting thing I noticed, in the new version all of the coins are synchronized.
think I saw this video closer to when it was released, but it got recommended again, and I'm keen to watch it a second time 👍
Thank you. I cant wait to play the finished product. I was thinking of playing this game again soon but ya know Im going to wait for this regardless of how long
Because of the tight constraints of early consoles, I always assumed, especially for a first party Nintendo game, that they were already very optimized. This blew my mind.
Well it was fairly optimized for what it was.
The game did work and people played it, it almost never crashes, so thats quite a job already.
At any stage of optimization there is another step to make it even better, so it never ends.
The cost to squeeze out some % might just become increasingly larger and costly, especially on understanding the code and potentially re-using it for some other game (as having hard-coded shadows in the code is a pretty bad approach if you want to re-use it).
It was pretty well optimized for the time
Hindsight 20/20. More is known about the N64 hardware now than when this was developed. Optimization techniques always advance. Like all technology.
Doesn't indicate this is not an impressive accomplishment. Just everyone asking why Nintendo didn't figure this out back then.
Like he mentioned in the video, almost none of this would've been possible without the RAM expansion pak.
It was already optimized.
Did you watch the video?
He explicitly says this isn't possible on the base n64 console.
7:23 This is very interesting. Usually I hear about compilers unrolling loops to optimize them, but here, the holdup is RAM, not the processor.
Incredible work all around.
Modern computers are also massively being held back by the RAM being so slow. I think the difference is that now we have more mitigations for that, like larger caches and speculative execution. This probably shifts the place where code-size vs conditional jumps balance out (conditional jumps in non-unrolled loops are also bottlenecked by memory).
@@kebien6020 also compilers are getting better at removing conditional jumps altogether. In modern C(++) code you don't have to manually remove most ifs because the compiler does it for you. I realized this when I wrote OpenGL shaders that aren't optimized at all I think so you had to manually do all the tricks to avoid ifs. Just by removing a few ifs in the shaders I gained much more performance than by implementing batched rendering
Did he say RAM or ROM at 7:23 8 and 16 bit systems run directly out of ROM and don’t copy any code to RAM for execution. A PC OS (IIRC) will load everything into RAM from disk barring external libraries.
Eight cycles JUST to load the next instruction from ROM is INSANE. Removing instruction cache would make the N64 run 100x slower
@@kebien6020 I seem to remember hearing one of the biggest advantages of M1 is how it can optimize the caches.
This was amazing. How did you end up with the source code?
god bless you, that footage is smooth!
Never been more proud to support a Patreon. Kaze you do so much.
Me: I don't understand so much :(
Kaze: It's mean VROOM VROOM
Me: Oh, i understand now
This is amazing! Any plans to release your fixed up code? I'm sure it'd be a boon to the community.
yeah i'll release it with the mod once its finished! a few other hackers already have access to parts of this and i share the big stuff.
amazing work
8:40 "It means vroom vroom" better be a meme
