Overview

chip8

A CHIP-8 emulator written in Rust

Goal

The goal of this project is to build a fully functional emulator (but I should name it an interpreter) of the virtual CHIP-8 device. Moreover, it has (and still serves) as a great sandbox to learn and experiment about the Rust language.

The source code is voluntarily and extensively commented for educational purposes.

Help

USAGE:
    chip8.exe [OPTIONS] <ROM_PATH>

ARGS:
    <ROM_PATH>    Path to the ROM file

OPTIONS:
    -h, --help          Print help information
    -s, --super-chip    Run as the SUPER-CHIP
    -V, --version       Print version information

State of the project

The program is "opcode complete" and runs correctly even though some improvements remain to be done (see issues).
