I've started this thread as my question is a page back now on the update and support sticky, as everyone is talking about 2.0. I followed the instructions in the manual. I copied the files over from "Blue Card (R4i)" to a FAT32 formatted SD Card. I then stuck the SD card in the blue cart, and loaded the deep labyrinth game. I then get the message "Can't open _dsmenu.dat" I downloaded the firmware and manuals from here. - http://www.gateway-3ds.com/downloads.html Yes, I've tried with and without the launcher on the SD. The manual doesn't mention putting the launcher on there until step 3. My 3DS is 4.5.0-8E.
