1. put your "config.txt" files in ux0 .......... but put all your plugin files in ur0
2. makes sure your "config.txt" in ux0 points to all the plugin files in ur0
3. keep the config.txt file, not in the same drive, as the plugins, see if that fixes the problem with adrenaline?

(doing a lot, alot of deleting controller configuration files with the "rebind option", then with the "rebind option" enabled, and I think .............. the retropie saved that into ram, and then made a mistake and placed it in its vram or something ? .................. anyway ... it was for the ps1 emulator, so it was the same files over and over, but i just reformated weeks ago to fix that, ....................... some files are not saved until the gui is closed?, best to try some things out before reinstall)
