I added iCade support to the iOS Build

Well, the similarities between a Wiimote and the iCade remote end at the fact that they both use bluetooth. The iCade simply emulates a keyboard and sends keystrokes when you press the buttons. Implementing it is fairly easy/straightforward. Supporting a Wiimote or any plug-in peripherals to a Wiimote takes much, much more. On the other hand, there's probably some decent open source libraries out there for reading input from a Wiimote, so if you do any development yourself, you could look into it and try to implement it. If you find a decent framework that provides you with some callbacks for buttons pressed, it's fairly easy to integrate them into the ppsspp sources.
