A NES emulator written in Odin

A developer created a NES emulator in the Odin programming language over seven months of spare-time work, achieving enough accuracy to run hundreds of games including Battletoads with features like save states, debugging tools, and sound support. While basic emulation can be achieved quickly, the final accuracy required extensive work on CPU-PPU timing synchronization and implementing multiple cartridge mappers, which the developer found significantly more challenging than commonly assumed.
