How would I hard code that?

Hi Graboid, sorry for such a delay in getting back! First chance I have had to have a proper look at this. I have followed your steps and I am 100% wired up according to your wiring diagram. I add the usb quirks line and reboot. On rebooting, none of the buttons work at all. I have tried pushing select and x together (as well as every other combination of two buttons) and cannot access the retroarch gui. I tried hitting f1 on the keyboard too and this won't do anything either so I can't see any way of accessing the retroarch gui to even see whether it now sees it as two controllers. However Lstest does show it as two controllers...

any ideas? really appreciate your help and hopefully I can get this running! I am using a pi 3 and retropie v 4.1 (have tried older versions too). What are you using and what version of retropie are you using?

Found the problem!

The PCSX-ReARMed.rmp file in /configs/psx/PCSX-ReARMed folder had only configurations for player 1, so I just duplicated the lines for player1 for player2.

Not sure where the wrong configs come from, but this overrides them.

Just to mention it here as well :-) The ControlBlock allows to directly connect arcade controls (which are mapped to gamepads) for two players as well as a power switch functionality to safely switch on and off the raspberry pi.

That would be sweet. One can hope.
