My 2022 R4 SDHC just came in, and I'm trying to get it run in order to use GodMode9i to back up some GBA saves. I've formatted the SD card, and downloaded the firmware files from the r4 site. However, it doesn't automatically start up, but the ds slot prompt shows a game called Deep Labyrinth, and selecting it only shows "Can't open _dsmenu.dat"
