I just ordered this: http://www.r4ibuy.com/products/NEW-R4i-Gol...7%7DDSi-XL.html In the list of features it says - No need to flash. Built-in launch Slot-2 (gba) function. But I'm not sure what this means. I'm new to the whole flashcard thing. Can it play gba games or did I just waste my money? Should I have gotten a supercard dstwo instead? Can someone help me out?
