I intend to make a game in the style of the original Gameboy, which comes with plenty of limitations. The limitations include having only four colors on a greyscale, a very small resolution, and some limitations on the sound system. I’m not very concerned with the colour or sound, as I can simply impose those limitations while making assets myself.
What I’m wondering about is how I can set up the game to run at a 160x144 resolution and making coordinates, or at least the rendered graphics, use only integer values. If there’s anything else I’m forgetting about what has to be altered, feel free to tell me.
