I indeed have a second power supply to run the Capcom I/O and the Raspberry Pi. I have both power supplies on remote switches so I can turn off (reset) the Naomi without shutting off the Pi or when done I can shut it all off without needing to get into the cab.You want a Jorge 2-in-1 cart bro... If using the Capcom IO for power you won't be able to support a NetDIMM.The choice is Capcom IO for power but then stuck with only carts, or real (2nd) JVS power supply and DIMMs.Net Dimm when I acquire it.
The only thing I am really missing is a Net DIMM and a Zero Pic, I have my friends but eventually I will have to give it back lol. I already have a lead on the Zero Pic.
