'Cause WUP Installer doesn't detect what devices are you using, and as far as I know, it installs directly to the first USB device you use.so why WUP prompt me NAND and USB ? (i only have SD Card on the WiiU slot)
And once the game is installed on NAND, i can remove it from SD Card ?
The option to install to USB doesn't work when you don't have any USB, and it will crash the program.
And yes, you can delete the files from the SD card after installation.
