Yes, probably the best idea. Let's see: - 3 reads and writes to PF1 (~19) - 2 reads and writes to GRPx (~16) - 2 reads and writes to HMMX, NUSIZx (~32) - 1 write to HMOVE (3) - minimal loop overhead (5) = total: 75 cycles Hm, the ball is still missing and then you might want different colors. I assume a 2LK kernel is a better idea. Have?fun!
