Maybe i'm doing something wrong but I get a guru after 2 loops of the title screen, after the insert coin screen. Running the WHDLoad version gives me the error "Exception "Illegal Instruction" ($10) at $FF occurred." at the same point.
Yay! I mean it didn't really matter as far as gameplay goes but I spotted it when just watching attract mode just to get an idea what to do :) Good work though! I love your ports
