Support for NTT NDK10 SNES Controller?

[Duckers]

Just wondering how hard it would be to get Retrode firmware support added for the NTT NDK10 SNES controller as documented here...

Currently the light on the Retrode doesn't blink when the extra buttons are pressed, however the general SNES buttons appear to work okay.

Happy to help test!
