I forgot that Flyball didn't have audio support which now reminds me of Atari Destroyer also being another example of no audio for an Atari game. I don't remember the other Atari games since most have been done earlier.
The other issue that I remember about Atari Destroyer is the video code is from late 1990s and for some unknown reason the 'Atari copyright' text image doesn't appear on the attract mode segment of Atari Destroyer. 'siftware' had dumped his Destroyer pcb years earlier and indicated how his pcb does show the copyright text image. iirc his Atari Destroyer pcb rom set was eventually added to MAME support.
I don't know if the copyright text appears or not when running Destroyer, but if not then likely some video emulation issue from the older era code.
The other thing I remember about Atari Destroyer is there was a language rom option in which operators could request the language rom as an extra item. I am not sure if that is supported yet or if that is a rom that has yet to be dumped and supported.
