Chip-8 Interpreter

Space Invaders in the Interpreter

A fairly simple Chip-8 interpreter written in modern C++, it features all of the standard instructions and comes bundled with a nice built-in memory and program debugger. I've tested space invaders, tetris and a couple of other games, and it seems to run fine. I haven't implemented sound yet though, that is still on my to-do list. Need to work on timer "synchronization" too.

Compiling and Testing

  1. Start up your favorite terminal emulator.
  2. Go to the root of this project.
  3. Issue make and hope for the best.
  4. You will find that bin has stuff.
  5. Either start the program or test suite.

or: makepkg -i if you're on Arch Linux.

Usage and Documents

  • bin/chip-8.out <path-for-rom>
  • bin/chip-8.out share/INVADERS
  • J: start or step the built-in debugger.
  • K: will resume normal execution.
  • 1, 2, 3, 4: maps 1, 2, 3, C on chip-8.
  • Q, W, E, R: maps 4, 5, 6, D on chip-8.
  • A, S, D, F: maps 7, 8, 9, E on chip-8.
  • Z, X, C, V: maps A, 0, B, F on chip-8.
  • ESC: terminates the interpreter.
  • You'll find some design docs in docs.

Dependencies

  • GCC 4.7
  • SDL 2.0
  • SDL_image 2.0
