I want to get the EZ 3-in-1 GBA cart for my DS, but I want to make sure I know what i'm doing/getting before I spend the money for it. 1.) I have M3 Simply. Is what I need to play GBA roms the EZ 3-in-1 cart? I assume it goes like this, but im not sure: put the 3-in-1 cart in the GBA slot, put a GBA rom on a mini SD and put that in the M3 Simply cart (like what I do for DS roms), load up the GBA slot from the M3 Simply menu, and there I can chose roms to play. Is this right? 2.) How well do GBA roms play? Is it like playing a SNES emulator? Or is like DS roms, where most games run as perfect as the actual DS game? Thanks for any help!
