I tried checking for clipping at all stages, then I realized it was mixing with a 32bit int, so that wouldn't have made a difference - but I ran the new code anyways, and sure enough, it made no difference.  I've seen this before, I think its coming from the psg/ssg part of the ay8910 - in some games (like the games from the new(to FBA)-UPL driver iq_132 had recently wrote), the ssg sound channel was about 5x louder than the fm parts (Atomic Robo Kid, Mutant Night), somehow this had been fixed in MAME when they re-wrote the entire 8910 code - at this point it would be impossible to graft in a fix, so I took the ez route and simply lowered the psg(ssg) channels to match the fm ones.  I can't see doing it for Metal Slug 5 though, the crackle of the gun actually sounds pretty good/non-irritating to me, even with headphones.  Thanks for reporting it, though :)

best regards,

Since I added support for the independent sound routes you can reduce the volume of each channel individually.

I can't test at the minute but I always assumed the gun sound was ADPCM, so not related to the AY part anyway?

It could just as well be :)

not sure if it applies to Metal Slug 5 because I'm not hearing it, but some of the later NeoGeo games were clearly developed using an inaccurate emulator (probably NeoRageX) as part of the development.

As a result Nightmare in the Dark has a really annoying crackle when you jump, it didn't happen in very old versions of MAME, and it didn't happen in NeoRageX, but it did happen once we started emulating actual limits of the chip properly, and it does happen on real hardware (so we emulate it)  Not respecting the chip limits actually breaks some other games in worse ways!

The dark-side of emulation. I guess it was easier to use a PC emulator for a quick test than a devkit?

Jees - you downloaded it quick - was up for like two minutes before I replaced it.

Download again to fix to get the correct version. :)

Sound, except for explosion, doesn't appear to be working in Galaga (even with the samples in place).

The explosion is the only sample. The other sound should be emulated and working.....

In the Megadrive driver, Wonder Boy in Monster World, the top 4 lines seem to display random tiles instead of the info boxes, I can't seem to figure this one out..

best regards, [attached - pic from FBA & pic from Gens/how it should look]

Oh yeah, in Wonder Boy I knew of this bug... and this two black lines on the side... it's terrible.  :eek:
By the way... it's a very fun game!

Hello everyone, Somehow when I load Gradius III screen just stays black except for the first time I loaded the (World) version which screen was gray and black and nothing happened. I tried loading that same version again and screen was just black for a few mins I would say like 5 mins before I tried loading it again.  I tried loading all 3 versions with basically same results. Don't know if it just takes a while to load but that seems pretty long.
