i picked up a 32 in 1 game boy multicart today which worked fine on the older style SP at the place where i bought it, but doesn't work at all no matter how i try to put it into the super duper backlighted SP at home. all i get is the game boy title screen with a black bar on the bottom where it would say "nintendo". the registered trademark symbol is still there. i have tried some other pirate carts i have on my newer SP and they do work, but this one multi just will not. is there some sort of hardware difference between the SPs, or is it just the ambiguities of pirate cart quality assurance?
