I think it mostly involves any game with the Actimagine/Mobiclip video codec, which happens to be a majority considering its distributed with the official SDK. Anyway, I'm getting black screen freezing on all of these. Is it the same on the AK2 as my RPG? I wish Acekard would do something about this, they seem to be slacking on all aspects. They're working on selling DSi friendly carts, meanwhile we still haven't even seen old Cyclo features like real time saving.
