Default [Q] Tab Pro 12.2 specific Roms?

1st
Are there any roms being developed specifically for the Tab Pro 12.2? I've been following THEDEVIOUS1's thread and tried his test version for the 12.2, but it's not working and I can't post there yet. I rooted my tablet and modified the platform.xml file to get full access to my external sd card. The only thing left is to get rid of Knox and whatever else Samsung did that's preventing some apps from full functionality.

2nd
In order to use my Wiimotes with a SNES emulator I had to purchase an otg to usb adapter from Samsung and a Bluetooth dongle with a CSR chipset. This does work, but you can only play until the battery runs out. Does an adapter exist that would allow me to use a BT dongle and charge my tablet at the same time. I really love this tablet, but beginning to hate this one port for everything crap. It would be great to be able to play an emulator game with Wiimotes on a big screen. Breakout box maybe?
