  • gb-research

    Game Boy hardware research

  • Gekkio's GB-CTR is a good reference of the SM83 (Gameboy CPU) with access pattern withM cycle accuracy. The GB-research repo by the same author also contains a lot of information.

  • SameBoy

    Game Boy and Game Boy Color emulator written in C

  • You could also consult the SameBoy source code which is a very accurate emulator.

  • DMG-CPU-Inside

    Reverse-engineered schematics for DMG-CPU-B

  • If you want to go deeper, you can look at the reverse engineered schematic of most of the stuff except the CPU core in the DMG-CPU-Inside project. You could also consult the MetroBoy project, which builds on the previous project and aims to be accurate pretty much down to the logic gate level.
