Yeah I was disappointed that I couldn't just keep .dvv files on sd (devo checks sd if the games are on sd but usb if the game is loaded off usb)...if only the .DVV files could be stored on the internal memory of the wii..
if the games are tied to the Wii, it shouldnt matter if the .iso is on sd or USB, only that devo finds the .dvv file related to the Wii used. I don't wanna touch the Wii nand if I can help it, so this would be preferred by me. (maybe devo can only read from sd or usb but not both and that's why this is the way it is).
