Request: Nintendo Power Pad Support for NES Cores

Hello Retroarch Team,

Love the program on my PS3 and cannot wait for the new revision! I was wondering if it would be possible to include Power Pad Emulation Support for the NES cores. I recently got the power pad working on the PS3 using UnoJoy (through an arduino uno) and would love to play some of the power pad games. I know FCEUX for the PC already has this capability and would love to see it come to retroarch and the PS3. Thanks and keep up the good work!
