I found about 3 or 4 of these at my local gamestop for $19.99 and I have a gamecube so i'm seriously thinking of investing in one...but i wanted to see what other people thought of them. Do they only play GBA games or can you play GB color and classic games? also... What all does this do? And does anyone know if they will make something like this for the Wii in the future? thanks. Serious answers please.
