Oh, I'm so happy to see this here. I'm avivace[0], lead of the https://gbdev.io 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.
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.
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.
Come join us on Discord[6] if you'd like to get involved and contribute.
