Oh, I'm so happy to see this here. I'm avivace[0], lead of the <a href="https://gbdev.io" rel="nofollow noreferrer">https://gbdev.io</a> iniative. Pan Docs is really a labor of love and we've been investing a lot of time in improving it and making it more accurate and accessible.<p>We do maintain a bunch of other stuff too! A Game Boy Assembly Tutorial[1], an open digital repository of Game Boy homebrew software[2] and RGBDS[3], the de-facto standard assembly toolchain for the Game Boy.<p>We also hosted popular game jams such as the gbcompo21[4] and gbcompo23[5], with winning entries usually going the long way and publishing as physical products.<p>Come join us on Discord[6] if you'd like to get involved and contribute.<p>[0] <a href="https://github.com/avivace">https://github.com/avivace</a>

A long, long time ago I started a YouTube series[0] on the internal workings of the Game Boy during a brief break from work. I eventually started working again and animating the episodes was taking way too long, so I had to stop, but I've kept orbiting the world of Game Boy reverse engineering.<p>The amount of dedication, skill, and passion that goes into it on a daily basis is mindblowing, and people keep discovering hardware quirks and bugs to this very day! I believe it wasn't that long ago that people discovered a glitch in the audio subsystem that gave you more control over note envelopes, and it was promptly added to LSDj (a tracker for the Game Boy that was first released in 2000) by the original author, who's still maintaining it to this day.<p>0: <a href="https://www.youtube.com/watch?v=RZUDEaLa5Nw" rel="nofollow noreferrer">https://www.youtube.com/watch?v=RZUDEaLa5Nw</a><p>EDIT: oops, forgot the link!
The gbdev and emu dev discord communities were indispensable when writing my GB emulator. They’re helpful and social and many can basically look at your corrupt output and suggest what vblank or other bugs you might have.<p>My first interaction was asking why the Nintendo logo would appear and never disappear and they immediately knew it was a rookie pitfall: I had my button inputs set to low which actually means pressed, so my emulator was resetting itself infinitely.
I wrote a Game Boy emulator as a pandemic project, and the pandocs linked here are indispensable. It contains all the technical documentation you need while leaving the implementation up to you. I tried getting into Sega emulators after, and while there is some good info there (SMS Power has good docs), none quite matched this.
a similarly comprehensive document for game boy advance / nintendo ds / lite / dsi:<p><a href="https://problemkaputt.de/gbatek.htm" rel="nofollow noreferrer">https://problemkaputt.de/gbatek.htm</a><p>i've got myself a dsi and at some point plan on doing some from-scratch development for it -- that single file should be enough.

Oh this is really nice and well formatted, all this time I use <a href="https://gbatemp.net/download/gba-and-ds-rom-hacking-guide.33419/download" rel="nofollow noreferrer">https://gbatemp.net/download/gba-and-ds-rom-hacking-guide.33...</a> for my romhacking project<p>I think this document would be a great resource for me to go really to the basics and this guide is well updated too so it's a plus
