This is what I'm referring to. I primarily have my games on the SD card in the system... a 128 GB SanDisk microSD card in an adapter. GameCube games run fine off SD, I just can't get to my Wii games on the SD card (the DSI error occurs when switching to USB when not having any thumb drives plugged in).
