Just why? Why not simply use the channel version?Is there a simple "forwarder" that can be installed to launch NUSspli-1.136-HBL in app folder from the Wiiu menu?
That's the Wii Us damn bad FAT driver and stuff. Reformatting the card might or might not help.it's very slow when clicking on "install" inside the progam, just like if it was taking a lot of time to find the SD card
