@bubble2k16 what I meant is that I tried doing that but it didn't work.
I tried all kinds of bios but still no luck.
Is there something that you can think of that people may get wrong?
Edit: By the way, when your playing and then touch the home button when you resume the display gets stick...
@Dodain47 I tried Madou Monogatari and bonanza bros. and they work.
In MM's case, it requires you to use the arcade card.
but bonanza worked fine without any need to change anything. So Do these games show text or do they just show black screen for you?
