There are a lot of different flash carts out there and it is hard to know which one to buy. I have heard Acekard 2i is good but the build quality is poor. I have heard the Supercard DSTwo is good but that it sucks battery life because of the extra CPU on-board. I have heard the R4 cards suck because of the risk of getting a knock off and that there are no updates for the card anymore. These are the ones that I have researched so far. Am I accurate in what I have said? Really, I just want to know what the best overall flash cart for the dsi would be. I am looking for a card that has good build quality, does not suck battery life, the best compatibility possible with DS games and that still receives updates. I am also looking for one that I am least likely to accidentally by a knock off of. Money is not really an issue. I just want the best overall card possible. What do you guys think?
