I was piddling about with the BASIC Engine NG, trying to think of game ideas. I'm from the Atari 8 bit world and color indirection made it wonderfully easy to color cycle stuff to give the illusion of movement. The BASIC Engine NG is plenty powerful to brute force a sort of fake color cycling.
Is there a method of 8 bit style color cycling by changing registers?
This is a very quick and dirty something I was playing with >>>
