Asura Buster Game freezing?

barbudreadmon

@minimanzer0 Well, lots of work was done to fix this arcade hardware over the last 8 years, so the higher requirement in FBNeo is expected. If you don't plan on buying a pi4, it might be worth checking if FBNeo with the cyclone core option can improve things for this specific game (i recommend not enabling it globally).

I doubt you'll have very good results with old MAME (if any result at all), even latest MAME looks like it might be behind FBNeo for this hardware.

@barbudreadmon I can't even get it to open in mame2003. But when I get home I'll see if I get to the same spot where it freezes, in fbneo.

@dankcushions ok so I tried the game with fbneo and it was running really slow with lagging sound (as I previously mentioned) but it didn't get stuck and freeze where the fbalpha2012 would get stuck. So now I KNOW it's an issue with fbalpha. That being said... How can I get the game to run full speed in fbneo? I honestly don't understand why it's running so slow. I have every neo geo game running in fbneo at full speed.

SN: the game doesn't even open in mame2003 or 2003 plus.

@minimanzer0 did you try the cyclone core option as @barbudreadmon suggested? https://retropie.org.uk/docs/RetroArch-Core-Options/

Read my previous post again...

@barbudreadmon ok so I just turned on cyclone mode and it had no effect on the speed or sound lag. :(

Is there anything else I could do?

Oops, it turns out it's using an improved model of 68k that's not handled by cyclone.

I believe your only remaining option to play this game is to buy a new device.

Asura Buster should work in MAME2003+ if you have the correct rom, but it will have some sound skipping problems, as per your issues running the
game in FBAlpha2012, this is due to that core not having a fix which was done to the M68K / M68EC020 CPU, now if someone was to backport said fix
to FBA2012 then all your problems would be solved :)

"Fixed odd-word/long reads and writes in the m68000 cpu interface which in turn fixes the nasty 68x020 bug that has been plaguing us for ages. This fixes freeze-ups in Asura Buster and other 68ec020-based games. [iq_132/dink]"

@barbudreadmon I'm certainly getting a rpi4 before the year is out.

@arcadez2003 Thanks for pointing out it was an issue with m68k intf, i had looked into the game driver and couldn't find the fix.
I did a PR at https://github.com/libretro/fbalpha2012/pull/99, but i believe such change will have a performance cost, even on classic m68k games (additional condition on every cycle, and the code for 68ec020 looks like it'll be slower).
