Problem running Blazing Star (NEOGEO)
-
Pi Model: 3 B
RetroPie Version Used: 4.2.5
USB Devices connected: None
Controller used: Wii U Pro Controller
Error messages received: All my NEOGEO games run flawlessly with lr-fbalpha except this one. When i reach the 1st boss of the game i simply loose the sound and music (with the exception of the insert coin sound). After i defeat the 1st boss and pass to the second stage sound and music are back until i reach the boss at the end of the level and once again exact same issue (no sound or music...). This is bizarre since it only happens 90% of the time. Every now and then i am able to get sound on those boss fights. If i use Mame2003, Mame2010 or lr-fbalpha 2012 i don't have this sound issues but on the other hand all those emulators have a graphical glitch where your ship cannot touch the left side of the screen and this has been fixed on the lr-fbalpha since version v0.2.97.38.
Emulator: lr-fbalpha v0.2.97.40
How to replicate the problem: happens 9 out of 10 times that i reach the boss at stage 1 (it only takes like 1 minute to reach that boss so it is pretty easy to check if this happens to you)
-
My first suggestion is to file a bug on the emulator's GitHub tracker, in case there's something that actually needs to be fixed in the emulator - in particular on the FBA front, as MAME 2003 isn't being especially developed these days.

I recently created the overlay for Pulstar and Blazing Star so I played a while.
Didn't notice any issue; will check about this problem this weekend and let you know.(edit: added correct link to overlay)

tested it just now with my system, which is going on about a month without being updated so FB Alpha v0.2.97.39 835951a. not the same version as you obviously, but might help narrow down a potential bug.
music plays fine as long as the Neo Geo mode is set to MVS in the retroarch options menu. switching to AES will cause the music to drop out when approaching the lvl 1 boss as you have described. further testing of the UNIBIOS mode i noticed some graphical glitches/black background textures.
all other system options are set to their defaults. if you want to verify, the md5sums of the contents of my blazstar.zip & neogeo.zip are pasted here:
edit: after further testing in AES mode, changing the BIOS to NeoOpen seems to work fine. i haven't tested others, so maybe it's the default BIOS (MVS Asia/..) that has this trouble?

Thanks for your help! How do i change the BIOS to NeoOpen?

I just updated to the latest build of RetroPie 4.2.3 and played through a few times on a Pi3-based system and it worked just fine for me.

I have 3 Pi3 systems, one with Retropie 4.1, another with 4.2 and one with 4.2.5 and have the exact same issue on the 3...
-
@NightRune I'm not sure how you're running RetroPie 4.2.5 as I just updated my systems two hours ago and they're at 4.2.3
That said, if you're having the same problem on all three systems, maybe it's your ROM?
-
@obsidianspider Sorry, i meant to say 4.2.3 and not 4.2.5.
I also tought about the rom being the issue but tried different ones and have the exact same problem.
@chipsnblip could you please clarify how you change the BIOS to NeoOpen?
-
sure, start the rom and from the retroarch menu (Select+x) it's under Quick Menu>Options>BIOS. from there you can cycle through all the different BIOS files conatined in neogeo.zip,as well as set the mode to MVS
-
I never encountered the problem with Blazing Star when trying it ~5 times, but when playing Night Warriors, I didn't get music in the first stage. I couldn't reproduce the problem after restarting the game 3-4 times. This missing music might be a rare bug.
-
No problems for me too (lr-fbalpha .40 on Pi 3).
-
@chipsnblip Changing the BIOS to NeoOpen did the trick for me. Thank you!
-
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?
