rchip8
(Yet another) CHIP-8 emulator written in Rust.
There's nothing particularly special about this CHIP-8 emulator, but it does aim to be faithful to the timings of the sub-systems. For example, it aims to run the exact number of CPU cycles before drawing the screen. It's currently hard-coded to run the screen at 60Hz and the CPU at 700Hz, but those values are easy enough to change.
Usage
rchip8 <rom_file> or cargo run <rom_file> if running from source
Controls
CHIP-8 has a keypad with 16 keys. This emulator uses:
1 2 3 4
q w e r
a s d f
z x c v
Apologies to anyone with a non-QWERTY keyboard...
<Esc> to quit.
