Gameboy Emulator built entirely inside VRChat
This is a gameboy emulator built inside VRChat using UdonSharp. It is heavily based on BlueStorm's ProjectDMG: https://github.com/BluestormDNA/ProjectDMG
I cannot guarantee that it is stable, but it passes the Blargg CPU tests (https://github.com/retrio/gb-test-roms) and it seems to boot into pokemon blue just fine.
This is almost playable. See the update I made recently. The game will be playable if I can get a 5x or so improvement. This is much better than previously.
