We all know that the Acekard 2i can run on the DSi, but its basically the same as the AK2. It still has the GBA functions and stuff. Is there a cart in the making that will be made grounds up, so to speak, for the DSi?
It would make use of the extra ram and CPU sorta speak, maybe the cameras.
From there a really experience developer could figure out how the game access those features and
create a flash cart or homebrew that will allow to unlock the DSi completely making it use all its "power" sorta speak.
