There could be some issue with savestates in the konami mystwarr driver, probably some pointer included in it. See https://github.com/libretro/fbalpha/issues/159

What i did to reproduce this issue in fba standalone is saving state while in ram rom check, then reload with the state.

I spent some time making serveral savestates at different points in time while the ram/rom check screen was up in Violent Storm, but every time I loaded the state it checked out fine afterwords. 
[A few moments later]  I also tried with the release version in a fresh setup.  hrmm,  maybe I'm missing something? :)

Check "restore full state on load" and use this one.

Hello people.

I realise interesting Bug on Cow Boys of Moo Mesa.
I just tried the game (moomesa.zip ) in mame. After i tried in FBA. In the FBA there is some scene missing.
This screen is from the game's intro

That should be correct. It's part of the FBA team's policy of censoring giant Lazer beams.

Hi hursit,
Thanks for the bug report!
This problem in Moo Mesa has been fixed along with the end-level boss scene, the problems were fixed last week but I didn't announce it yet :)

Hi everyone,

Someone at github reported an issue with sounds on neogeo : it seems some games have missing sounds when you select a mvs usa bios or the usa+arcade setting with the unibios. The games reported are bstars (no music when the game start), nam1975 (no sound at all ingame), karnovr (no sound in selection screen + ingame), and some clones, i don't know if it affects other games. I can confirm it happens with official fbalpha.

Is that a bug ? I've been wondering if those sounds aren't just missing from the usa version of those games.

Hmm i'd go with a USA Bio's bug, as surely too many sounds are missing to have been a regional change.

barbudreadmon, its a bug in fba.  if you uncomment the #undef speedhacks at the top of neo_run.cpp (see // #undef SPEED_HACKS) it will work.  I think it would be a good idea to convert that to a dip setting like you did in the other drivers, if you want.  (or, if the games work fine on rpi with speedhacks disabled, just leave them disabled?)  What do you think?

The raspberry 3 should be fine with those speedhacks disabled, i'm wondering about older/slower devices though. I'll make some test and let you know by pm the results.

That Neo Geo speedhack is nothing but trouble. It doesn't even really do anything noticeable for most games. Maybe it should just be removed.

Excellent, yea, it would be nice to remove them or at least give an option.  The thing is, people have been raving about our neogeo support for years, and I really hope disabling this speedhack doesn't uncover anything more serious or cause problems down the line.  Would you try some previously problematic games, like s1945p, and see if there is any regression with the speedhack off?

thanks,

I'm observing a ~2% performance decrease without the speedhack (i underclocked my rpi3, checked the fps with and without the speedhack, it went from ~50 to ~49 fps), and s1945p is running fine when i'm back at normal clock, i don't think this speedhack is worth keeping.
