This will only partially close my #7626 report, right? Definitely a very good job for all these PRs. Respect - keep it up! :)

Yes, this PR will only fix the audio. The video issue is a duplicate for #4635. You can avoid it by using a webcam at 160x112 or OBS

japanese karaoke revolution is working and judging my singing harshly.

okay. cool. i thought maybe the interface to the ps2 was stereo and each microphone took one of two channels. i don't know if two players was ever possible then.
