I think it's finally actually done: #c64 #Pongwars
It's _so_ slow: the calculations take more than one frame per frame, so it runs at 30fps; this run is mostly taken at Warp speed emulation (10x). Much of that is because I kept BASIC running, to reuse its number output routines.
Somehow this ended up being 800 lines of assembly: https://gist.github.com/Two9A/8b2f1d6e750e4ae762b2b9e2d7512473
I'll find a few spare moments to write up articles on some of the subtleties, expect those in the coming ...months.
