The card boots up just fine with another MicroSD that only has 200 games, but when I insert the MicroSD with 622 games the card boots up to the screen where you pick "MicroSD" or Favorites folder, it works just fine until you try to access the games in the MicroSD, then the whole thing freezes and becomes unresponsive. Its running wood 1.62 and flashed latest firmware. Really need help, thanks!
