Hi, I'd like to buy a gba flashcard but I'm almost total noob about those flashcards. I've seen many of you recommend the ez-flash iv, but I've also heard that they an't play some games (like fire emblem, which I would like to play). Why? And which one is better? Where can I buy on of them? Personally I would play it mainly on my NDS Lite (and maybe on my purple gba)
