The old issue(s) now fixed and gameplay video behavior is like it should be thanks to hap's work from last month.

As for discrete audio part, that may be a while before audio is fully emulated via discrete emulation instead of external audio samples. External audio samples can only be done if the sound effects are simple single noise/one shot sound efffects...anything more complicated such as motor shift sound effects used for 1970s era Atari Sprint series games can not be done using external audio sample recordings.

iirc Astro Invaders manual has logic schematics for audio sounds.
