Freddy,
Eek!  To help me track down the problem, let me send you a debug version of FBA via pm, please run it and attach a screencap and the file zzBurnDebug.html (you'll have to zip it before attaching it to a message here)

thanks,

It seems in Metal Slug 5 the A B C or D buttons do nothing during gameplay, the directions work just not the face buttons.

Just tested and nothing wrong for me with the A B C or D buttons...



Which pad, gamepad are you using? Which Os and which FBA version?

Mayflash PS to PC controller converter, Windows 7, FBA 029730 32 bit since 64 bit is kinda buggy.

OK found the problem, its the universe bios 3.1 thats causing that strange glitch where the face buttons dont work during gameplay.

Edit:  its ALL versions of the universe bios doing it, guess I better send a bug report to Raz.

Thanks for the infos SNK_Dude  :smilie:

Could you tell me which setting are you using with unibios 3.1 (Arcade or Console, Region, etc...) to see if i could reproduce this bug?

best regards,
JacKc.

Start metal slug 5 in arcade mode then switch to console mode in the Uni-bios, in order for the controls to work you have to get a gameover which is strange I know :P

Just set your lives to 1 in the F2 menu and hurry and die and then they will work .

Edit:  seems the sound problem still persists from previous versions in metal slug like when you shoot your pistol and the sound is crackly , can you please check on that as well?

SNK_Dude, try Audio -> Disable FM Interpolation, it usually fixes any crackles/distortion w/Neogeo games.

The gun sound sounds alright to me, I'll admit that in mame the gun sound is a bit muted sounding, but I don't think it sounds bad in fba at all.  What do you guys think?

The only potential for any issue I see is that we don't clip the result for each stage in burn_ym2610.cpp. Only the final result is clipped.

In reality this may make very little difference.

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 :)

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!
