The WiiKey Setup disc ISOs have been added to the helpdesk for download.
Quote:
We’ve uploaded a setup disc version which will automatically turn the region free mode on (for those who don’t have a GC controller handy). We will upload another setup disc version which will allow cycling and selecting the menu options with the Wii’s RESET button later on this week. Meanwhile we are working on additinal features and improvements for wiikey and the configuration menu.
