Progress continues...Most of my parts have arrived, and I got an old broken NES that I will cut down (the one I drew all over is my brothers and since it is actually working I didn't want to cut it up). The aluminum panel came today and all my switches and connectors arrived Saturday.
I ran into some trouble on the Retro Duo with the NES cart slot not working well (it doesn't release cartridges well and it looks like some pins are bad). As a result I decided to separate the SNES board and focus on that for now. I may end up getting another NES component so the two are completely separate. There are a few manufacturers that make a NES on a single chip and they are relatively cheap. This will also simplify the switches and power source.
So I pulled off the bottom connector to the NES board which is not needed for the SNES function, I then wired in the A/V out and 5V in direct to the SNES board. In addition I removed the switch and wired it to always on (I will control the power from the source) and bypassed the reset switch.
This also cuts the board down very small, I think next I will set the SNES aside and start some work on the N64, once I get the power and A/V off of the N64 I will try mounting both to the Aluminum panel I picked up.

From the Side, the four N64 controller ports on the top, just below them in the middle will be the SNES port's, and the Wii will be housed in the bottom (I will probably have to extend it a 1/2 inch).
