CHIP-8 interpreter written in Python

Contents

About

CHIP-8 is an interpreted language developed during the 1970s.

chip8py is an interpreter that can run any program originally designed for the CHIP-8 platform.

Installation

The project uses pygame to render the window:

python -m pip install pygame

Clone this repository into a folder:

git clone https://github.com/robertolaru/chip8py.git

Usage

Running python main.py --help will provide the list of arguments the program supports:

usage: main.py [-h] [--cps CPS] [--fps FPS] [-c] [-m] program

positional arguments:
  program            path to the program to load

optional arguments:
  -h, --help         show this help message and exit
  --cps CPS          cycles per second. Default is 500 cps
  --fps FPS          window rendering framerate. Default is 30 fps
  -c, --cpu-view     enable visualization of CPU registers, stack, opcodes
  -m, --memory-view  enable memory visualization. Also enables CPU visualization (like --cpu-view)

To run the program, you need to provide the path to the rom file (program) to load in the interpreter:

python main.py program

Using the keyboard

Originally, user input on CHIP-8 was done through a 16-key hex keyboard.

The interpreter maps the original keys to the leftmost portion of QWERTY keyboards:

 1 2 3 C         \       1 2 3 4
 4 5 6 D     -----\       Q W E R
 7 8 9 E     -----/        A S D F
 A 0 B F         /          Z X C V

(original)              (interpreter)
