== DETAILS Well, after a lot of code analysis, this seems like the best way to handle things on the Wii U without also completely re-architecting the I/O handling in RetroArch. How it works: - the top-level wiiu_joypad driver is now nothing more than a delegator. - the wiiu-specific drivers live in `wiiu/input/` - wpad_driver.c handles the WiiU gamepad - kpad_driver.c handles the wiimotes - hidpad_driver.c will handle HID devices like the GC adapter, DS3/DS4, etc. (I say "will" because this isn't implemented yet) == TESTING Haven't actually tried the build to see if it works, but it does compile.
