I wouldn't recommend you use this code as a reference for building an emulator, not because it's bad code but simply because it is in an unfinished state.
Some useful references are:
- pandocs (reference docs)
- mohanson/gameboy (Rust emulator)
- djworld/gameboycolor (Go GBC emulator)
- LIJI32/SameBoy (C emulator)
