I just got a EZ IV for my micro a few days ago, I love it. The major con I guess is patching, but the patcher is actually really nice and auto formats the name from like "mther3translationasjnfaf.gba" to "Mother 3 (J).gba", so I'm actually really glad it has to be patched. The card is a little slow too in saving on bootup and loading a game, but really it is worth it. Great price, Flush, Mini SD.
