Hello! I run a Nintendo 3DS (not XL) that was bought for my birthday last year and recently I bought a gateway card to go along with it. I followed the video instructions on the downloads page for the gateway up to the point when he clicked on the 'Deep Labyrinth Atlus USA, inc.' I did buy this in England, second hand. Apart from the games the old owner might've installed there is nothing I have put in the 3DS game except the gateway which doesn't seem to work. Sorry for not using technological language, I don't know much about the 3DS. I used to do the same with an r4 on 2 ds lites but this 3DS I have failed . When I launched up Deep Labyrinth, this shows up, 'An error has occurred. Press and hold the POWER Button to turn the system off. Please refer to the Operations Manual for details.' After I start up, everything is normal. But would someone please help me solve this so I can play games on my 3ds? ;D -Yara PS : My SD card for the 3DS is a '2GB SD memory card Toshiba'. I haven't plugged this in to the PC so I haven't touched it yet. Thanks in advanced, and please ask if you need more info.
