I bet RDC at acidmods.com has voard scans for the PS5. I can take a look and see if i can find some schmatics for ya!
I wonder what the insides of a PS5 look like. It really wouldn't take much to get this adapted to PS5. We were so close with the PS4 Berserker, I literally had a working prototype and the software would recognize it when connected and I think there's even PS4 button graphics in the forge. I can't remember what happened that we didn't release. PS4 I really didn't have much space for a big modchip
