Well color me retarded. I didn’t realize that had a solution, and I’ve read that link before. I guess I overlooked it because I never intended to use original SNES controllers, but it wouldn’t hurt to have that option open. Thanks a bunch!

Edit: upon further investigation, I am not sure this is the option for me. With how the controlblock is positioned on the board, it wouldn’t fit with the heatsinks already attached. I was also intending on using the power button on the console (ps1), rather than a toggle switch. Kinda bummed out; this is such a good solution otherwise.
Then again, I do have a gpio breakout from my canakit…and I could replace the power button with a switch in the same spot…hmm…..dot dot dot….
