This build has the player moving in X and Y directions and with cleaner handling of the dirty tile to remove the inefficiencies. The good news is that there is no longer any performance problem at 2.8 MHz now that the inefficient dirty tile handling has been removed. The bad news is that they player leaves garbage behind indicating some kind of problem with dirty tile marking. But it is close.
