@navyseai said in Is Retropie dead?:
python 2
Bullseye Buster was (due to the reason that Python 2 EOL was in 2020 (IIRC)) the last OS that came with python 2 and python 3, Bullseye and Bookworm are Python 3 only (retropie builds fine on each of them (32bit flavour), not sure whether 64bit still includes some culprits (though mine seem to be working fine (Bookworm 64bit/Pi4), but that is just running with a few selected systems)).
