atomheartother / chip8

A simple chip-8 emulator in C++ using SDL2 with desktop & browser support

C++ip-8

This is a super simple CHIP-8 emulator weekend project. It uses SDL2 and can be transpiled to WASM using EMScripten to deploy on a website.

Demo: https://chip8.navennec.net/

Fully functional on Linux, Windows, Firefox, not tested on other platforms.

Installation

• git clone [email protected]:atomheartother/chip8.git
• Install cmake
• mkdir build && cd build && cmake .. && cmake --build .

EMSCripten build

Same as above but you'll want emcmake from the emsdk. Then:

emcmake cmake .. && cmake --build .

Running

./chip8 <rom file> [instructions per second]

(The default value for instructions per second is 350).

Bugs

• On Windows, the beeping sound is way too low
• Sometimes the screen disappears or doesn't draw anymore in browser if you keep loading new ROMs.
