This project is a Chip 8 emulator (interpreter) written in Cuis Smalltalk.
The original goal of these project was to learn how to code a simple emulator in smalltalk.
A collection of public domain ROMs that can be used with this emulator can be found at:
- https://www.zophar.net/pdroms/chip8/chip-8-games-pack.html
- https://johnearnest.github.io/chip8Archive/?sort=platform
After cloning this repo, open a workspace in Cuis and type:
Feature require: #'Chip8'.And then:
Chip8 runProgram: '/path/to/rom/filename'.The CHIP-8 had no specified clock speed, so we'll use a delay to control it. Different games run best at different speeds, so we can control it here.

The original Chip 8 had a keypad with the numbered keys 0 - 9 and A - F (16 keys in total). Without any modifications to the emulator, the keys are mapped as follows:
| Chip 8 Keypad | Keyboard Key |
|---|---|
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 |
- Automatic ROMs download from Zophar
- Better morphic configuration (to configure speed, roms download button, pause, etc...)
