Hello, I've got a bit of a problem here.
Recently I've uploaded some new roms on my Batocera.linux, namely Monkey Ball for MAME. I couldn't make it work, so I put the standard MAME core and it started an infinite loading screen with no way out. I reset it and rebooted it. Now it's frozen on the "batocera.linux" page (the very first one) and doesn't boot at all! What can I do?
