I downloaded some ios and cios wads, updating things so they'd run more smoothly, and after I installed Waninkoko's 249 rev 20, the channels/usb button and the return to buttons disappeared off of my wiiflow 1.1. 2.2 was unaffected, but 1.1's vanished. So I reinstalled rev19. Anybody else have this problem? Is there another version of rev 20 I can try, or should I maybe use rev 21?
