How to build it

You should be able to launch it by running 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 in res/roms. You can also drop the Space Invaders wav files in res/snd if you have them.

To build the .app bundle for macOS, you need to have SDL2.framework and SDL2_mixer.framework file in /Library/Frameworks folder. Then you can open the .xcodeproj file and build the project.

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