@sf_junkie said in Odd Sound Issue with Neo-Geo games when loading a save state:

lr-fbalpha

I don't think anyone is gonna provide that kind of support for several years old version of our project (i certainly won't), so you should use the current version (FBNeo), furthermore that issue is probably something we solved long ago because afaik those games work properly with runahead (which saves and load states at every frame).

@Armyguy31b01 https://www.libretro.com/index.php/goodbye-fbalpha-welcome-fbneo/

@drylightn I just tested it myself and what I suggested is still correct. And you should be able to skip with any button on the controller, but that's isn't too important - that you can skip is.

Once you have configured every other controller but before you confirm the controls at the very bottom, use the D pad to move back up to the triggers. Then try to assign the trigger buttons, ensuring that they are set to +AXIS (Mine shows up as 2 and 5 for left and right triggers respectively).

Good in theory, but AFAIK the retroarch devs have no intention of implementing said feature in the short to medium timeframe. lr-fbalpha having it would be a lifesaver, there are a lot of 2, 3 and 4 buttons per player arcade cabinets out there that badly need it. What's the last lr-fbalpha version that fully supports it?

@wiggy808 said in [SOLVED] - Final Burn Alpha (lr-fbalpha) not playing rom sound samples file:

Is there a clrmame or other program that can check the samples files to let me know they are incorrect / incompatible?

The list of needed wav files is included in the dats i provide at https://github.com/libretro/fbalpha/tree/master/dats . Clrmamepro should be able to tell you if you have all needed wav files if you setup "Sample-Paths" in Settings, then check "Samples" in the scanner, it'll only check filenames though, not crc.

@barbudreadmon said in lr-fbalpha DAT Rampage World Tour conflicting ROM files:

@riverstorm That's definitely an issue in the fba code, i'll report it upstream.

Thanks, missing one ROM from the whole set...aaargh! ;)

@mediamogul

and I think these with same issue:

Arch Rivals
Rampage
Xenophobe

I was able to resolve this issue by putting the sample directory back into the original directory as stated.

/home/pi/RetroPie/BIOS/fba/samples/

After this, I updated lr-fbalpha again, how this time I did from source rather than binary. After this, I restarted EmulationStation and the samples worked perfectly again as they did prior to lr-fbalpha v0.2.97.42.

as far as i can tell, this behavior can be different depending on the BIOS. load up a neogeo rom for instance, and you will see a retroarch quickmenu >> options entry you can change to a few different button combinations (Holding Start being the default). then take 1942 for example in where holding start does nothing, and you must activate the service mode from retroarch quickmenu > options then restart the core.

also, there is a line in /opt/retropie/configs/all/retroarch-core-options.cfg

fba-diagnostic-input = "Hold Start"

that might be what you're after.
i'm not 100% certain on all this but i hope it helps point you in the right direction.

Is it possible that the aes has a ram/cpu limitation or something that may be the reason why it disables the music during the boss fights?

@edm203 said in Sengoku 3 for neo geo:

lr-fbalpha

Managed to work it out and got the FBA optional package installed, buzzin.

@edm203 No, I added my own. There seems to be an issue with emulationstation getting the correct name too.

Nevermind. Found it. Under Retroarch, it's quick menu -> options, then last option which is max players. Change from 2 to 4.

I use lr-fbalpha for most arcade ROMs. My guess is that you need newer ROMs. Update your image to the latest Retropie and then find some new ROMs.
