Okay, I've been thinking about purchasing a Slot-2 card with my R4. I don't know which one I should get. The EZV 3 in 1 Expansion is fairly cheaper than a M3 Lite Perfect...here. I can't really find a place with just a M3 Lite Perfect not in some kind of a combo package that doesn't require PayPal. However, the G6 Lite 4G looks so tempting... So, I guess my question is, if I just want to play some GBA games along with some NDS games, would the EZV 3 in 1 Expansion be sufficient enough (not sure if the NDS-GBA linkage works with it)?
