Help please for Vampire moon

Using Acekard 2i with AKAIO V1.8.1.The game opens and plays but then if you move back to say the settings page, then try to return to the game, all you see is a blank screen. This occurs at other occasions aswell.Is this a fault with the rom or the firmware.Thanks for your help.

Having same sort of probs.....No one any the wiser?

it will be the firmware.
