I've played through all of KH1.5 Final Mix with no issues on this version (after changing the render to Vulkan and some SPU settings as suggested on the forums) other than the after credits freeze (#4851) which isn't a big deal.

Now I'm trying to play Chain of Memories and I haven't changed any settings. Sometimes I freeze during the initial cut scene, sometimes I freeze after the cut scene when I get to the logo, and even if I skip this cut scene I freeze in the next cut scene.

I've seen two different errors so far in the log shown in UI, the most common one being RSX: nv406e::semaphore_acquire has timed out. semaphore_address=0x403008D0. Here is the screenshot and logs:

Once I got this error instead: cellVdecDecodeAu failed with 0x80610103 : CELL_VDEC_ERROR_BUSY [1]. Screenshot and logs:

@gsingh93 @Baxusfox still freezing?

@gsingh93 @Baxusfox still freezing?

I'm not them, but this still occurs.

There's something going on with the FMVs in KH 1 & CoM. It will either randomly crash during FMV play back, or right after it ends.

I've worked around the issue by renaming the PAM video files in the game dump so the game no longer attempts to load FMVs. This workaround also fixes the credits crash in KH 1 since you can't skip that cutscene. Definitely not a real fix, but it's suitable for me until a proper solution is discovered.

#4851 is probably the same issue, but the difference is that one is always reproducible for me

As of [RPCS3 v0.0.8-9724-df1813b4 Alpha], I am still having the same issue.

On my side, the game does not freeze on the opening FVM.
By the way, the emulator crash and exit after the following dialogs, before controlling the character.

The workaround of issue #9655 solves this problem too

[archbunkz]

is there any chance of another workaround or solution? i'm unable to disable accurate dfma due to my cpu supporting FMA

Workaround is simply to hit the start button and skip the cinematic.
You can get in game this way. Otherwise you're still today stuck on the cutscene as soon as the title of the game shows up.

@gsingh93 retest
I got some slowdown but can no longer reproduce freeze on latest Master. Don't forget to use new cache.
No workaround needed

So, I have no idea why no one tested this, but libvdec.sprx fixes the issue of the game freezing when intro cutscene ends. I figured this out myself and couldn't work out why no one tried this option (edit: turns out duckhost did but failed to mention it, or that it was what fixed the problem). I figured it may have been fixed by one of megamouse's recent libvdec PR's which was why no one mentioned it... But I went back to an old build, and it was still working.
