[RPi3] Exception OSError #2151
In the terminal, after leaving the retropie_setup.sh, I got this message:
Yes, it was a sys.exit() exception likely caused by repeated calls of signal_handler. Increasing the sleep in the loop would help but no guarantee it would stop this in all cases.
I also tried to make joy2key.py instead pass a signal back to the parent bash process which joy2KeyStart could wait to receive, but didn't have much luck yet. Best to just leave this alone for now as it's just wasting your time.
