george-emu

a ramshackle emulator for george 😌

plenty of inspiration & guidance taken from emulator_6502 (don't use george-emu in a serious project! emulator_6502 is the crate you're looking for)

structure

see the george wiki for how george works, why she exists, who she is, etc.

the george emulator contains 3 main structs: Cpu, Mem, and MemMappedDevice. Cpu represents a 65c02 processor, with functions for interacting with memory and executing instructions. Mem is a collection of MemMappedDevice's, which each hold the data for some address space. Mem can add MemMappedDevice's, and read from and write to them. A MemMappedDevice can have multiple banks at the same address space, and can translate 'global' addresses to 'local' ones (e.g. 0xFFFF in the system's memory map corresponds to 0x1FFF in the ROM).
