Reply To: Easy update to 2.6 and GBA setup?

When I upgrade I tend to just use the latest image, and copy the roms back.
You may want to grab your controller config which (if you are using the auto files) is in /opt/retropie/emulators/retroarch/configs/

Or it may be hardcoded in /opt/retropie/configs/all/retroarch.cfg

But to be honest it doesnt take a min to reset them using the retropie-setup script
