A NES emulator in Rust. Written as a learning project, to learn a) Rust and b) how emulators work.

How to use

Build with cargo build --release and then run the nes binary with a ROM as the first argument, or simply run with cargo run -- my/nes/rom.nes.

Controls

Hard-coded at the moment.

Up: W
Left: A
Down: S
Right: D
A: L
B: K
Start: Enter
Select: Space

Should I play games on this?

Oh god no. This is a toy project that I wrote for my edification. If you actually want to play games, use something that people actually maintain.
