I re-flashed a couple of times and the SNES emulator never worked and never launched with Batocera 35, also worth noting that I have No emulators to select for the system,
I re-flashed with a build of Batocera 33 (Link below for you UserUserUsername9000) and this worked for me and DOES launch SNES games and works perfectly. It is worth noting however that even in this version whilst it works I still do NOT have the ability to select my choice of SNES emulator like in other systems.
So my current solution is Batocera 33 with updates switched off (but at least I have my GPi case running again), I have tested gb, gba, nes, mastersystem, megadrive and snes, that’s enough for me at the moment, I hope this helps and if anyone has any other idea around Batocera 35 and why the config is broken I would be happy to do more tests.
