After implementing mappers 1 and 2 along with all the interrupts I've been able to run a few more games. Unfortunately "run" doesn't mean "play", most games fail to get past the title screen.



I can play a couple games though:





Every game seems to have sprite issues though. Mega Man seems to load sprite RAM with garbage and doesn't display anything, the pacman demo requires a bunch of palette hacks and in asteroids the ship sprite gets all messed up on some of the rotations.
