Tomb Raider Anniversary jump to horizontal bar issue

[roylaza]

What happens?

In Tomb Raider Anniversary - Egypt - Temple of Khamoon (level 9 I believe) there is a section where a jump backwards to a horizontal bar is required, however Lara doesn't extend her hand to the bar and so falls to her death.

I have uploaded a video I've shot of this in action:

What should happen?

Lara should extend her hand after the jump and cling to the horizontal bar, as seen in the below gameplay footage:

What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.

I am using PPSSPP Gold v1.6.3 (Android) on a Sony Xperia XZ2 with Snapdragon 845 and Adreno 630

Attached are my saved game and save state

Thank you

Just moved my game to the PC (version 1.4.2) and it works there, and I've also notice that Lara is starting the jump backwards from much higher which might explain why she can't jump correctly on 1.6.3 (for some reason the place where she holds the top bar that you need to jump off of is higher)

It would be super helpful if you could try a range of older versions from https://buildbot.orphis.net/ppsspp/ and try to narrow down when this broke. Also, you're not using the option to change the CPU clock, I assume? That can throw things like this off, we've seen that before...

Hi Henrik

Yes I will try out some older versions, I've just tested the latest version on both PC and Android and the PC version does not have the issue while the Android version does, so atleast we know this is android-specific.

I'm not changing the CPU speed

@hrydgard I've tested a few versions but the lowest I can go is v1.3-740-g5ba53addb and this version has the issue, is there a place where I can download even earlier versions?

If you go into developer tools, and switch to "IR Interpreter" instead of "Jit" (it will be slower), does this still happen? You can use a save state to avoid most of the slowness.

It might be that it never worked on Android. But it also might still be related to a setting. Make sure you're not using cheats and don't have any hacks enabled.

@unknownbrackets Amazing! you are absolutely right, switched to this option and suddenly Lara lets go of her suicidal tendencies :)
And as you've said, this slows the game down to a crawl but at least it allows to pass this part and then switch the setting back

Thank you very much!

Great, another ARM64 JIT bug then :)

[roylaza]

Thanks guys, I'm kind of honored that my finding will help make this amazing emulator a tiny bit better :)

Here's another interesting finding:

She just keeps slipping on the gate! So jit makes games smoother by making them greasy, right?! LoL

As noted, it doesn't happen on IR interpreter.

@Leopard20 That's pretty funny :) is that using my saved state? haven't notice this behavior myself.

[Leopard20]

No, I used your in-game save to progress to that point. I just figured it might've been triggered by something else. So I didn't use the savestate.
You don't notice it even when you unthrottle the game?

[roylaza]

@Leopard20 You are right! she does slide, I guess I haven't stayed in one place long enough to see it

Another interesting finding:
JIT still works, but you have to be quick (otherwise she'll slip!) and also jump from near the left-side edge:
