Summary 07173: ozmawars, ozmawars2: Missing/different sounds in Ozma Wars
Description I assume that it has to do with the current ROMs marked as bad dumps but, just so that it's documented somewhere, here's a video of the original PCB, playing the missing sound effects:

(Proper sound recording starts at 00:24)

Oddly, the comet doesn't play a sound effect for some reason. May be a bug due to it appearing right after the player recovers from a hit?
Steps To Reproduce Insert coin, start game

One of I'm sure many space invader hardware games which don't have in MAME unique discrete setups and simply uses what Space Invaders uses.

Nothing to do with that.

Correct sounds have been added.
