Forgot to mention. I’m using the 3.4 disk image on a pi2 over clocked with the pi 2 setting and memory split is at 512.
Edit: so I’ve solved my psx performance issue and got amiga working properly but still having problems with the nes30 pro pad . I followed the guide to the letter but no way can I get the pad working in emulationstation , it’s recognised in retropie setup and I’ve triple checked the manual file edit I made. On restart it connects to the system but doesn’t show up as a new pad in emulationstation
