ok i (at least) got the no bios error msg now..

adding system_directory = “/home/pi/RetroPie/BIOS/psx” (and creating a seperate folder) removed the message no bios found, but i still get a segmentationfault when i try to load a savestate and progress in the game
… ok it seems that the loadsate wont work if you switch bios in between.

i (think) its working now
