Mooneye GB is a Game Boy research project and emulator written in Rust. The main goals of this project are accuracy and documentation. Some existing emulators are very accurate (Gambatte, BGB >= 1.5) but are not documented very clearly, so they are not that good references for emulator developers. I want this project to document as clearly as possible why certain behavior is emulated in a certain way. This also means writing a lot of test ROMs to figure out corner cases and precise behavior on real hardware. The emulator is lagging behind hardware research. I don't want to spend time making short-lived and probably incorrect fixes to the emulator if I'm not sure about the hardware behavior. On an i7-3770K desktop machine, I can usually run ROMs with 2000 - 4000% speed. Without optimizations, the speed drops to 150 - 200%, which is still fine for development purposes.
