The R4 for the 3DS is to allow to play DS backups on it, not 3DS ones, if you read what it says on the package it clearly says DS and doesn't mention 3DS roms anywhere, so far the 3DS hasn't been hacked so there's no way to play the roms.Really? So I bought an r4 made for 3DS that wont actually play 3DS games? What the frick.. Thanks anyway.
