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.
The NES board has been removed with the A/V and Power directly connected to the SNES board (thank you Retro Duo for labeling the board). In the lower left corner where I hardwired the switch to have the SNES always on and bypass the reset.
I was happy to see that everything still worked after tearing the whole thing apart. The Retro Duo is surprisingly sturdy.--Dan
