chip-type-8

chip-type-8 is a CHIP-8 interpreter / emulator built with TypeScript and Preact 🎮

Features

The original 35 instructions for CHIP-8 are all supported and the interpreter can be used to to run games like Pong, Space Invaders and more. Additionally a few Super Chip-48 / HP48 specific instructions are implemented which are used to save register contents to flags and load the flags to registers. These instructions are supported so that the interpreter passes the SCTEST test ROM which can be used to partially verify that a CHIP-8 interpreter is correctly implemented.

No sound effects are supported, although the sound timer itself is implemented.

Building

To build the application via webpack:

npm install
npm run build

Tests

Run npm run test to execute tests for:

all 35 instructions
sanity checks for basic virtual machine operations
sprite drawing

But why?

Hundreds, if not thousands of CHIP-8 interpreters exist so what makes this one so special? Nothing really as there are way better CHIP-8 interpreters out there. I just wanted to try out TypeScript as well as create a super simple interpreter / emulator.
