Hi. So i bought 3ds for my sister along with acekard card compatible with 3ds, i installed akaio and update for 3ds. i tried to play 5 games, only one of them worked. all of them were 5200-5500 games. i have white screen even if i tried to disable anty-piracy. any ideas? maybe shall i try to buy r4 (but i would like to take this step at the end, i dont want to spend another $$). Thanks in advance!
