Zsolt removed a ROM patch from the driver init at the same time he did some other cleanups. Maybe it shouldn't have been removed?

Confirmed on win7

Screen doesn't flip in cocktail mode either.

interesting thing of note, this does NOT happen on the cosmicgi set I just added

ROM_LOAD( "7.8h", 0x1800, 0x0400, CRC(84656c97) SHA1(2180faa07dd5bc618c80ae033babfc1191a0b890) ) // standard label but different anyway?

this ROM from cosmicgi appeared to be an unmodified universal one from the label ,and using it prevents this from happening although there are more than a few bytes changed.

note, the cosmicgi set has a different issue with the graphics leaving trails but that happens on the real pcb too, and could be some deterioration of rom 4.

I wouldn't bet against both sets having minor rom corruption, it's a very old board.

(note, I've attached the cosmicgi PCB picture I was given, 3,5,6,7 appear to have more original stickers / stamping than 1,2,4,8 which are the ones modified for Spanish language on this bootleg)

I recommend an original Cosmic Guerilla PCB be dumped for comparison.

This also happens outside of the demonstration during regular gameplay.

If you play the game normally, get a game over, then start a new game, the game will freeze on your first death.
At this point, the only thing you can do is add credits, with various side effects (garbage line, erasure of the score, beeps, ...).
