I downloaded the CRISP "Get a whiff of this edition" 128GB image for my Raspberry Pi/RetroPie.
I wanted to add Sony PSP as a system, it's added ok and I can launch the games, but I don't know how to get the PSP artwork/video etc to show. I got all the PSP snap videos and wheel art etc for games, and I have a Sony PSP.mp4 video in the right place in the /opt/.../.attract folder with all the other system videos but it doesn't show in AM.
Is there a step-by-step guide to adding a new system?
Many thanks
