That was it! Thanks so much. This is going to be a gift for my wife and I didn't want her to have to worry about USB's being plugged in.

But i didnt used the scraper function at all .
I used an image to install retropie with roms and everything .
Start it up and all info and images are there next to the games .

I add 3 psx games with my usb stick , restart retropie and all the images and info are gone next to the games . Only the gamelist is there .

Without using scraper for those 3 psx games i added .
