Jane - Just another NES emulator

Just another implementation of a NES emulator written in Rust.

A note of warning: This is an exploratory coding project with the aim to understand concepts of assembler and emulation in general. If you are looking for a cycle-accurate ready-to-use NES emulator to play some games, this is the wrong one.

Usage:

./jane super_mario.nes

# With optional start address for the CPU (mainly for debugging)
./jane nestest.nes C000

Make sure to compile with --release for 60 fps.

what works

• CPU
• Reading Roms (iNES)
• Memory mapping and RAM
• A very simplistic debugger

what does not work

• GPU / graphics
• APU / sound
• Controllers
• a lot of mappers
• game saves
• everything else
