Hi Spidi, I hope you still read this thread and are open for more ys MkII irmware updates. As also can be seen in this thread
http://eab.abime.net/showthread.php?t=86497 On my CD32 I'm using a combination of:
Rys MkII with latest firmware
8Bitdo wireless USB adapter:

8Bitdo SF30Pro (not plus) wireless controller and PS4 dual shock controller
Both controllers work fine in joystick, pad & CD32 modes. However, the button mapping is totally weird and confusing. Can I still provide you with the info using the tools mentioned earlier in this thread so you can provide an updated firmware?
