Summary	05237: cosmicg: Demonstration stops at end of 2nd loop
Description	When you demonstration happens, the ship dies eventually and things are looped back. On the 2nd death, the game sort of hangs there. AFter a while longer, the score starts to flash. You can credit and attempt to play but when you die the game ceases again, this time you need to RESET or RESTART MAME.
Steps To Reproduce
Additional Information	Notice if you credit, you see the bullet which was hung up continues on it's way to the bottom of the screen.

No.09710 Haze Senior Tester Aug 7, 2013, 20:24	interesting thing of note, this does NOT happen on the cosmicgi set I just added furthermore 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.
No.09711 Haze Senior Tester Aug 7, 2013, 20:30	(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.

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, ...).

No.19627 Haze Senior Tester Jan 5, 2022, 02:29	fixed with what I'd say was a hack though, I do wonder if MT needs a new 'resolved' type for that, because I think a better solution is still needed.
No.19631 Fujix Administrator Jan 5, 2022, 04:57	A major hack will need to add new resolution to mt ;-)
No.19652 Osso Moderator Jan 7, 2022, 08:36	Since the consensum it this is due to a bad dump and the bad dump has been patched (again), I'm marking this as closed. Hopefully another PCB will be found and the bad ROM will be redumped.
No.19660 Osso Moderator Jan 8, 2022, 06:36	Although the fact that boot the original and the bootleg have the same presumably bad bits does seem to throw a wrench in this theory.
