@mitu I had the same issue! I also noticed somehow all the files inside the /opt/retropie/emulators/retroarch directory was missing, so I forced the updated in the core packages configuration menu inside the Retropie Setup screen. (Manage packages -> core -> retroarch -> Update from binary)

Yeah I'm thinking it might just be best to start from scratch and be done with it. I'm just hoping I can put my roms back on it. I do have a back up on my computer but I can't access my roms individually, I'm still learning how this stuff goes but might have to start over on that which is too bad cause I had over 5000 games...
