Coding the MMC1 Mapper

The MMC1 was Nintendo's first advanced mapper, used for many beloved games like Blaster Master and The Legend of Zelda. It's packed with features: PRG ROM switching up to 256k, CHR ROM or RAM up to 128k, software-controlled mirroring, and 8k of working RAM (WRAM) that can be battery backed for saving games.
