@BuZz I Flashed another SD card that i had when i first got my switch, I mounted the image on the "new" sd card with the latest image 4.6 of retro pie and i do have the ability to use controls, so now all i have to do is import files from the other card.
Finally got it working, I Had a backup of an older image I kept. Retropie 4.4.1
So I will need to check which version of reicast it is, also do you know if I choose to update the retropie script and update the OS and other emulators BESIDES reicast…. it should not effect reicast at all?
Thanks for the link to older version.. will have that as backup plan if need to.
deleting the subfolder's (emulator) retroarch.cfg files made it work again on any emulator that had trouble finding my ontroller. on first start it recreated retroarch.cfg from the retroarch-folder. seems to be default setting.
