>>13 Yeah, some are slow, and some don't run. I'll quote from the forums on the Supercard site as to why:
"This is simply a software problem. They decided to use a softwareroutine in vertical blanking interrupt for exit game function. But in several games there is no time in vertical blanking interrupt left for extra routines. So adding extra routines makes impossible to run the interrupt 60 times a second wich causes the slowdowns. Try to turn off all of the patch features and you will see no slowdown. But of course you cannot save because you cannot exit the game. So its a demonstration only. The manufacturers of sc could simply fix this issue by adding a battery backup to the sram. This would make possible to turn of gba, turn it back on and save then. This would not require exit patching so no slowdown would occure."
