Ok so I know that the Acekard needs a slot two device to play GBA roms on it. I also know that supercard has built in GBA emulation so you don't need a slot two. For anyone who doesn't know they do this by adding ram in the supercard cart it self. Any way my question is if you use a 3DS in stead of a dsi or lite could it be possible to run an emulator for GBA roms. I realize that some one might have to write an emulator or maybe someone could port a version of visual boy advanced. With the extra power in the 3DS I don't see why you would still need a slot two device.
