Some games not playing

hi
is there a reason why i cannot play some of the games on my acekard 2i?
Example are Hysteria hospital (stays black) and scene it twilight (stays white)
I used to be able to play hysteria hospital on my old dstt card on the regular nintendo ds...
I do have the latest version 4.21 of the emulator on the card
please help!

Try AKAIO, it is better then the official firmware, and might solve you problems, it can be found on the AceKard website's download page.

I accidentally changed the file on my games and now I can't change it back to the one with the gaming controller the one it previously had .Please help me or I can't play my games.PLEASE.

I'm gonna need some more information before I can help you.
