Summary	02036: gwarb: Guwrrila War bootleg uses two Y8950 sound chips
Description	Guerrila War pcb, same romset of mame, uses a second Y8950 instead of the YM3526 used in mame. I know it's compatible but for the sake of documentation it should be changed.

No.01756 Kold666 Developer Jul 23, 2008, 07:58	uhm, that's what I have read somewhere and since the sound rom is the same it should be. I think the bug should be resolved then, fujix?
No.01781 Kold666 Developer Jul 25, 2008, 05:02	Since the chips are identical in behaviour and other bootlegs could have the normal ym3526 I change to resolved
No.01793 Tafoid Administrator Jul 25, 2008, 14:09	Kold666, I'm changing back to acknowledged until such time that MAME is changed to have both sound chips as your PCB shows. In general, documentation or side-by-side bugs are not resolved unless MAME makes use of the reports. If it's a bug fixed in MAME, then we can put it as 'fixed' and a version. Thanks for the research :)
No.02222 nicolasa Developer Aug 26, 2008, 10:52	I've added a note to the source stating the the bootleg has two Y8950. Chaging the machine driver doesn't seem to be appropriate since the Y8950 is obviously used as a YM3526 replacement. The sound program is the same as the original set.
