This is an NES emulator and a work in progress. The CPU and PPU work, though there are still at least a couple bugs. I’ve mostly tested on Donkey Kong and Super Mario Bros. so far. There are plenty of full-featured emulators out there; This is primarily an educational project but I do want it to run well.
