What are the best ones? I bought 2 DS-xtreme and my computer nor DS won’t recognize them.
That card isn’t very good. Good ones, well that depends on what features you want it and how much you want to spend.
R4: cheap, easy, simple, cheap SD micro.
Original R4s have been produced for along time now, any about now are clones of one card or another except for one card which is just the M3 team trying to jump on the R4 names band wagon. Even the price wouldn’t save as a Acekard 2 can be had for under Â£10 and AKAIO (cards firmware) is one of the quickest thing to be update when something doesn’t work.
