A CHIP-8 emulator library and SDL2 application written in Rust.
chip8.rs can be used as both a standalone emulator application and a generic CHIP-8 library.
Clone this repo, ensure that you have the SDL2.0 development
libraries
installed, and simply use cargo run <ROM> where <ROM> is the path to a
CHIP-8 ROM.
$ cargo run -- --help
Chip-8 Emulator 0.1
Shawn M. Chapla <[email protected]>
A Rust/SDL2 CHIP-8 emulator.
USAGE:
main <ROM>
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
ARGS:
<ROM> Chip-8 ROM file to load.
As a library, chip8.rs can be used for everything from instruction decoding
to full on emulation. For an example of how to do the former, see the code
in src/core/cpu.rs. For an example of how to do the latter, see
src/bin/main.rs and all files in src/sdl.
A Google search for "chip8 roms" turns up a number of results, many/most of which should be compatible with this emulator.
For information on the CHIP-8 architecture and how various instructions should be implemented, I referred to the following resources:
- The CHIP-8 Wikipedia Page
- Cowgod's Chip-8 Techincal Reference v1.0
- Mastering CHIP-8 by Matthew Mikolay
I also used Starr Horne's chip8-rust application as a functionality reference, although I tried to avoid looking at any of his code until my implementation was mostly complete.
