yeah, for some reason the replacement batteries I got had their little wings reversed compared to the original, but it's soldered in correctly. The part facing up in the video is + and it's soldered to the + pad on the top left. You had me double checking to make sure it's right. It works though!

Awesome, glad to help!

I believe the roms were from archive.org/details/no-intro-nintendo-game-boy-color-20170702

You're right, nearly all games have their own menus. I'd love to try an everdrive with save states to see if that gets around my inpatients but they cost more than I can justify! At least the video was short right?

@@systemoflevers lol sorry for the grumpy comment~

I mean, you make a fair point! The flash cart menu doesn't add that much hassle! That little extra friction makes it just a bit harder for me to want to use it. I probably need to just pick a game and start having fun with it though

For sure, A to Z subfolders are the way to go, not just dumping all the ROMs in a single folder like I did! What flash cart do you recommend most?

@@systemoflevers I only have the EZ Flash jr. No complaints so far. Perhaps the Everdrive is better? I don't know. But it is also more expensive...

Yeah, that's why I have the EZ-FLASH Jr, price. The everdrive seems so expensive! Have you ever had the EZ-FLASH Jr glitch out and lose a save? I haven't but it's something I worry about.

😮 I totally forgot to mention patches and ROM hacks! Flash carts are a great way to play with different patches and hacks on original hardware

@@systemoflevers ...aaaaaand, if someone - like me - is writing their own game and wants to test it on original hardware.

I agree, I have similar problems with emulation. I just think you get more value from an emulsion handheld than a gameboy flash cart.

Good to know!

Unfortunately I think there's nothing you can do except find someone who does have one. Which sucks as an answer

I had a line in this video talking about how I thought the battery was rechargeable but it's not. I cut it out though because I couldn't figure out why I ever thought it was. I'm glad I'm not the only one but I'm sorry you had to learn the hard way. Now I wish I had left the line in! The button is a good point. I never really thought about it as part of the flow of saving, but I'll be sure to use it whenever I'm done with a play session to force a save backup.

I'm glad it was helpful!

Thank you!

good, nvm. figured it out :]

I think it should be usable in gb studio. If you have any issues though please let me know and I'll try to fix them!

Just so you know the ez flash jr doesn't have a save state feature (unless I'm missing something). It only handles normal game saves. It's kinda confusing because it has an "auto save" setting but I think that just automatically backs up the normal save file from RAM to the SD card. The EVERDRIVE-GB X7 does apparently have a save state feature, but like you said, it's expensive! I don't have one, so I don't know how well it works.

@@systemoflevers 🥹 Thank you. You’re correct, the EZ Flash Jr doesn’t have a save state feature. You’re not missing anything, I misunderstood it. I’m new to all this and so I often misspeak but you’re right 🙂 I was confusing the two. It does have the auto save setting but I also believe it only handles normal game saves yes 🙂 and you’re right on the Everdrive gb x7 does have that save state feature however it really is expensive! I’m sure it’s worth the money and it’s only a one time purchase (at least it should be) but it’s still a lot of money upfront! Thanks for the clarification on the ez flash jr ☺️

I just got a new camera so I can do a zoomed in 4k version now!

A flashed copy if possible. Going through the ez flash UI to get to a game can be annoying... I also like to play one game at a time too, so the convenience of having a bunch of ROMs on the ez flash is lost.

Unfortunately I don't know of anything you can do, sorry. Maybe there's a retro game store near you that would let you use a gameboy to upgrade the cartridge?

@@systemoflevers Yeah, I am asking my mates around the town. It is indeed hard to find a gameboy or advance. But cheers mate. Thanks for the info!

Oh jeez, that's a good point. I can totally see the FPGBC having more issues with bus contention than the DMG. I'll see if the change fixes things. Thanks for the advice! I'll double check the address lines too. I'm extra glad I posted this video now!

I'm glad it was helpful! I hope you have fun with it!

Nevermind, there's literally a video showing exactly what I asked for :) (even has pokemon blue on the thumbnail)

Awesome! I hope you like the rest. You should definitely watch the entire 10 hour fireplace one, good stuff, definitely not just a short loop repeated over and over 😁

I'm glad you found it!

Alright so testing, I turned down the speed and that seemed to work. Very strange.

Yeah. It's not an ideal way to play, but it's better than nothing I guess. The consensus seems to be that the glitch happens with games that use the gameboy color's double speed mode

Thank you, my pleasure! I hope you make good use of it

Nice! I didn't try but I will now and let you know

Ok, just tried this. I was able to backup the save and use it in an emulator. I had some problems getting a good connection with the cartridge and it didn't work, but after taking it out and trying again it eventually worked fine

@systemoflevers awesome thanks for letting me know! I can't wait to get this shiny cyndaquil off this fake cart!

Good luck! I hope it works out

My pleasure!

It's the pinci github.com/camrbuss/pinci. Pretty similar to the sweep, and yeah using a pi pico. It uses the choc mini low profile switches (PG1232) and I'm not a big fan of those switches it turns out. I like the keyboard though!

Thanks, I was definitely inspired by him!

Thanks! I've definitely been thinking about a color version

Nice! How far along are you? Is gbdk easy to setup and on what OS? I've been meaning to check it out for a while but haven't gotten around to it. I mostly do simple demos and proofs of concepts using assembly and RGBDS. Writing everything in assembly gets a bit tiring though. You may have to wait a while for that video, I'm working on a video about sprites/objects first and it's making slow progress. I get most of my information from gbdev.io/pandocs/ but it's more of a technical reference than a guide though. But the idea is to put the window so that it covers the screen. Then you wait until it's at the desired LY (gbdev.io/pandocs/STAT.html#ff44--ly-lcd-y-coordinate-read-only) while in HBLANK, then turn off the window (gbdev.io/pandocs/LCDC.html#lcdc5--window-enable) so that it's off for the rest of the screen. You can detect the desired LY by setting LYC (gbdev.io/pandocs/STAT.html#ff45--lyc-ly-compare) (you'll want to set it to the last line you want displayed for the window) and using an LYC STAT interupt (gbdev.io/pandocs/Interrupt_Sources.html#int-48--stat-interrupt) by setting bit 6 of the STAT register (gbdev.io/pandocs/STAT.html#ff41--stat-lcd-status) then setting the HBLANK (mode 0) STAT interupt by setting bit 3 of the STAT register. Once that fires you'll be in HBLANK and you can turn off the window. Or you could set LYC and and just use the HBLANK interupt, then every HBLANK you can check bit 2 of the STAT register until it's set, meaning you're on the desired line. Hopefully that makes sense, helps, and gives something to start from. If you have any questions feel free to ask! I got some inspiration for this video from th-cam.com/video/Ty-qFeYK2l8/w-d-xo.html, it might give you some ideas too.

I just tried plugging my fpgbc into a Chromebook and it opened as an external drive. I didn't try actually changing the firmware but I'd expect it to work. Hopefully! Good luck and I hope you enjoy it!

It should just work. What emulator are you using? On the webpage were you using the "limit tiles" option? I just tested now using wasmboy.app/ and it was working for me with and without the "limit tiles" but maybe I have a bug where it's not generating the ROM correctly with some input sequence... If you want you can send me the ROM that it generated for you and I can have a look. My email is in the channel details. Or you can share a link here.

I was somewhat confident it would fix the problem. The symptoms of a failing power regulator board matched what I was seeing. I'm not sure what I would have done with this video if it wasn't the problem though!

You have the ezgb.dat and the Update_FW5_7-31.gb (or whatever the gb file is named) on the SD card?

@@systemoflevers I have both on the SD card. They simply don't show up on the Gameboy. I've tried it on the FPBGC and an SP console.

huh, that's weird. How old is your ez flash jr? What version is it currently running maybe it's only able to upgrade to 1.05 from 1.04? I don't recall how to find that info and I don't have one on me right now to check. I'd also be surprised if it hid the update gb file though. You're able to get other gameboy roms working on your SP with the ez flash jr right?

I have the same issue. I'm able to get it to boot from my gba, but the file doesn't show to update. Games load normally from the gba just fine. Just doesn't want to read from the fpga.

the trick for me was renaming the file just "Update". the extra characters made it not show up.

Oh, hah! I didn't realize

You should check out my next video then! th-cam.com/video/cuJsgaNXgSo/w-d-xo.html 😜

@@systemoflevers lol woops

From your other comment, in case someone else sees this and it helps them, you got it to work by turnin down the brightness before loading a game.

Wow, thanks! I'm still working on the next graphics video about sprites, it's taking a bit longer than expected though! The channel is growing nicely though and I get some very nice comments, so thanks!

@@systemofleversTake your time if needed, your production quality is unmatched.

Yeah, I can hear my DMG struggle through the speaker when it's loading a big ROM. I have a gb boy colour and it can't even boot with it, I assume because of the power draw

Use Energizer lithium non rechargeable batteries. They can provide a ton of current and last a lot longer than alkalines.

wow, ok so i had my brightness turned up and it wouldn't load any roms, but turning down the brightness and suddenly it works! thanks!

Oh, glad you got it working. Was your battery low? Were you able to put the brightness back up?

@@systemoflevers Yes, I could turn the brightness back up, it's just the most power draw happens during ROM loading. My battery was fine. I switched to n EDGB from AliExpress for half the price and been much happier with it for my non-RTC games. And for games that need RTC, I highly recommend Bennvenn's MBC3000. It fits 2 ROMs on the cart and you switch between them using dip switches.

Oh no! Does funny playing have useful customer service? Does the system turn on at all? Is there audio? If your friend is nearby and willing to take a risk you might try using their working system to diagnose yours. You could try their screen with your motherboard and your screen with theirs. Maybe have them do the assembly though, in case you're cursed The risk is that something is fried and it fries their components

Yeah! Good point. I didn't know these repro carts were rewritable until recently. I'm thinking of doing the same as you and getting a stash of them. I hear not all work though, do you have particular ones you get?

Oh nice. Good thing you had all that! I didn't realize the super gameboy was so cheap, that's wild
