Originally following the Emulator-101 tutorial, but diverged when tutorial switched to Cocoa.
Goals
- Tests passing
- Attract Mode Running
- SDL Taking Input
- Game Playable
- Sound
To run Space Invaders you'll need to provide a ROM, the ROM generally comes in 4 parts:
invaders.e
invaders.f
invaders.g
invaders.h
Copy these files into ./rom and run using make && ./intel8080 rom/invaders.
To add audio to the game, you'll need to provide the sounds yourself. The program uses .wav files. The files should be named as such:
UFO Move -> 0.wav
Player Shooting -> 1.wav
Player Death -> 2.wav
Invader Die -> 3.wav
Fleet Movement 1 -> 4.wav
Fleet Movement 2 -> 5.wav
Fleet Movement 3 -> 6.wav
Fleet Movement 4 -> 7.wav
UFO Hit -> 8.wav
Run make test && ./8080testrunner
Tests will take around 5 minutes to run
