How to build

ROMs

First of all the project requires the ROM files for the game. These are copyrighted and can't be uploaded with the project, but can be found online. In the project folder they should be saved in a folder called /res/roms/. The following files are required:

• invaders.e
• invaders.f
• invaders.g
• invaders.h

Building the project requires a C compiler and is easiest built using make.

Dependencies:

• SDL2

Ubuntu 18.04

1. Get SDL2 library:

    sudo apt install libsdl2-dev
   

2. In project folder, run:

   • gcc:

       make && ./spaceinvaders
     

   • clang or other compiler:

       make CC=clang && ./spaceinvaders
