RetroDuo NES/SNES Clone Official Thread. Castlevania III, StarFox WORK, SMRPG WARNING

[Franky]

I wired a NES connector to the RetroDuo and it works just fine. So now I can use the Messiah pad while playing the NES side. NES lightgun is next on my experiment list, but I need another SNES pad for the extra pins/wiring, as a regular SNES pad leaves two signals unconnected.

I'd love to see a schematic for this, as well as some more info on how compatible it is. Specifically, I'd like to know is the Four Score/NES Satellite can be made to work on the RD.
