Experimental Chip8 interpreter, cached interpreter and JIT compiler written in Rust. There is a GUI frontend and a TUI frontend.
The JIT is only available on x86_64.
The Chip8 controls are mapped on the keyboard and on the numpad. TUI only has the keyboard mapping.
For each table below, the key in each layout square is the corresponding Chip8 key.
