I'm about to buy the Supercard, (duh!) And I've recently seen that a game might not perform as well on certain, crappy microsd cards. So before I even buy the dstwo supercard. What's a reliable. 2 to 4 gig, micro sdcard for use with the dstwo? I'm probably going to use it mainly for roms and Homebrew...( preferablly buyable from a local store like Bestbuy or Walmart.) Thanks a lot and God bless lol
