Thanks for the Bluetooth update.
Since the Bluetooth stuff has mostly been reported by WiiU testers, how about some regular BC Wii love?
I tested on my original Wii and used a WiiU Pro Controller (it could use some sensitivity or deadzone adjustments on the sticks, they're extremely sensitive, almost to the point of being unable to walk slowly in most games.. and if you're curious, I synced it at the Wii Menu with the red button on the Wii, but of course, it doesn't actually connect officially; you can test if it synced by using the power button on the WiiU PC to see if your Wii turns on or not).
Here are the results of my quick test, testing only if the game boots and goes in-game, and if it responds to my Bluetooth controller (basically, I'm not here to report bugs in sound/graphics or already existing controller issues (e.g. Sonic)):
Ikaruka: OK
Zelda Collector's Edition (Z1/Z2/20 minute TWW demo/etc): OK
Zelda MQ/OoT disk: OK
F-Zero GX: OK
FF Crystal Chronicles: Black screen (I'm unaware if this is new to 2.153 or not)
Fire Emblem: OK
GC Preview Disk 2003: OK
Mario Kart Double Dash: OK
MGS: Twin Snakes: OK
Metroid Prime 1: OK (rumble is extremely weak though)
Metroid Prime 2: OK
Princess Peach Demo: OK
Paper Mario: OK
Zelda TWW: OK
Zelda TP: OK
Mario Sunshine: OK (lacks analog triggers, but that's just a flaw with the WiiU PC, not Ndont)
Smash Bros Melee: OK
Pokémon Colosseum: OK
Tales of Symphonia Disk 1: OK
Zelda Four Swords Adventures: OK
Not Tested (pointless, since they don't work or don't work well anyway):
PSO 1&2
PSO 3
Mario Kart Arcade GP2
Results: 19/20 (23 total, 1 failed, 3 skipped)
Seems like a winner, all-in-all, at least for original Wiis. *Shrug*
Fun little fact: If you plug in a GC controller, the Wii U Pro will auto adjust its positioning to be the highest numbered player (for example, 1 GC controller + 1 WiiU PC = the WiiU PC becoming player 2, and when you unplug the GC controller, it'll automatically go back to being player 1 without needing to reconnect), like the USB controller(s) do. Pretty nifty.
As an off-topic thought, I wonder how challenging it'd be to back-port some of this Bluetooth stuff (mainly the WiiU PC support) into libogc-based homebrew (I don't care about commercial Wii games). It'd be neat to add WiiU PC support to postLoader..
