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.

your bootleg might do, others might not if as you say, they're compatible...

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?

Since the chips are identical in behaviour and other bootlegs could have the normal ym3526 I change to resolved

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 :)

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.
