Features:

  • full emulation
  • sound
  • colourised screen (can also play in black & white)
  • two-players mode
  • joystick support
  • web export to HTML5 using emscripten
  • high score automatically saved

How to build it

You should be able to launch it by running:

mkdir build
cd build
cmake .. -DROMS_DIR=/path/to/roms
make
./invaders

It has been tested on macOS 10.13 with clang and debian 8 with gcc 5.

You'll need to have the files invaders.e, invaders.f, invaders.g and invaders.h. You can also drop the Space Invaders wav files in the same folder if you have them.

You can also build it for the web if you have emscripten installed (for macOS, install with brew install emscripten). Just replace cmake .. with emcmake cmake .. to obtain four files invaders.(js|wasm|data|html) which can be hosted on a web server.
