I'm not sure if there is an error in their instructions or my product is defective. I could get it to boot with no passkey in GBA mode but it gave the message Warning! Can not find card. I can get it to boot with the passkey set to passkey one, but the only thing it will play is DS roms. If I put it in GBA mode I get the same error about not finding the card. I have tried several cards with no luck. Im I doing something wrong? I havn't been able to run the set up rom because of this.
