Guten Morgen,
Zu deinen Fragen kann ich nicht wirklich antworten.
Aber folgendes habe ich im 4.1-Unstable Bug Report gefunden.
C64 : is listed but no emulator behind. Needs a b*mp to a SDL2 version rather than this SDL1 version. For people who REALLY want to play: you'd need to kill the vice process, through SSH, then all other launches should work ok until you reboot. I still haven't figured out how to configure controllers for that emulator yet, help would be appreciated.
