Running

main

This will get 50FPS on an 020, and 25 or lower on an 68EC020 and below. There's a branch related to precaching even more to get the speed faster but I'm defering that until later.

Building

Vamos

You'll want Vamos and SAS/C on Vamos's path:

ruby ./image_converter.rb && touch images.s && vamos -- smake
