I noticed in the RPi 4 build that Daphne is an available core. I haven’t been able to get anything to work. Is there a log of progress? It would be great to see these laserdisc games running.
AFAIK, it “works” except for audio.
Thanks. That’s too bad about the audio 
I’ll have to see why my setup isn’t working. Is there any documentation that might help guide me?
Not really, unfortunately. As an incomplete core, it hasn’t really been documented properly.
