joinski Thank you for replying! Ok, I’m running 5.26-dev on a Pi4 2gb. I was using a Dualshock 4 just fine, no problems until I added a ton of roms for Final Burn Neo. It was over 6000 roms, so I suspect that it eating up the MicroSD card’s storage had a part to play in why some of my games weren’t working. However, it doesn’t explain why my controller just stopped working and I can’t get it to sync any bluetooth devices to it anymore.
