Forced slowdown in Legend of Legaia hyper arts, items and magic?

[Rumba121]

The issue also occurs in standalone PCSX-ReARMed, even with unai renderer.

Description

Its not a major issue, yet an annoying one. In this game (scus version) while in combat you can execute hyper arts, spirit and magic summoning all appear to have an initial slowdown which desyncs the audio from the image.
¿any idea how to solve this?

Steps to reproduce

Play the game with any renderer open-gl or dispmanx or unai, enter a combat and execute a "Hyper Art", use an Item, cast a Magic or use Spirit.

When did the behavior start?

Always.

Your device/OS/platform/architecture

Device pi zero W, pi 3 a+ and pi 3 b+
OS raspbian buster with retroarch 1.9.1 with Lakka nb (from 21-03-30) cores, Lakka nb and retropie 4.7.1

Does this still happen ? I believe this is a counting issue just like how some games suffer from this.

[Rumba121]

Haven't tried lately, (my pi is collecting dust for some months), I will try it probably on next Sunday, and post update. Sorry for the late reply.

This does seem to be still happening at the present. (Also somewhat-related, I can hear some noise/hissing on this game even with sound interpolation set on Gaussian, unlike in DuckStation/Beetle PSX.)

How to reproduce this? I went to the tutorial fight with Tetsu, which involves abilities mentioned in the report and couldn't notice anything wrong. What device and which version are you using?

[JosepMC154]

"r24l 9fec7ce" on PC/Xbox Series S and "r24l 92bb759" on RG353V with PSP BIOS, NTSC version with Restored Progression hack. It's a bit hard to tell on its own because one can simply assume it's the game itself, but if you compare with footage on real hardware, you can see there's no slowdown in things like hyper arts.

Here's a save about 6-7 hours in, with some arts and magic unlocked to check out. Beetle PSX behaves more like in real hardware.

I don't know what you're getting but I fail to see much difference from the footage.

Could you try boosting "PSX CPU clock" in "Core Options -> System"? If it helps I'd like to know the minimum value that gives closest speed to what it should be.

[JosepMC154]

I don't know what to say, then. For me it seems to happen especially when using hyper arts like Tornado Flame or Frost Breath, where the character animation slows down a little and the audio desyncs momentarily. Maybe it'd be better to ask for more feedback?

Boosting the CPU clock makes everything smoother, but doesn't quite fix it...

If at least this helps, the audio noise/hissing I was hearing is gone after turning off the SPU's reverb, so that seems to be the culprit there.

[notaz]

I can't seem to hear any hiss either. Here is an audio recording on how it sounds here doing Tornado Flame, does this have the hiss? I guess the slight choppiness during "explosions" is the first issue?

Yup, that choppiness happens because of that was stated in the OP.

About the "hiss", I meant in the game as a whole, while playing the sequenced BGM and unrelated to the thread's issue. It can be heard occassionally while playing with reverb on, most noticiable while opening and closing the pause menu. My fault for going off on a tangent.

Other than these two things, the game runs pretty well. None of them are dealbreakers, just annoyances to keep track of in hopes they can get fixed eventually. So don't feel pressured to look into it.
