Dragon's crown sometimes won't boot.

[JacobAL]

Just hangs at black screen on trying to load trophy data.
Only happens in recompiler (LLVM/ASMJIT) and will happen most times I try to boot the game. Sometimes it will just boot and work fine though.

Not a problem on interpreter.

Please upload a full log.

[JacobAL]

Here's the log
This one booted to the loading screen and then crashed. (Weird because that hasn't happened before, usually it works if it gets past the blackscreen.)

Here's another log using D3D Here, instead of a black screen, I get "Setting up trophy data" without the data loading at all.
Unfortunately, once past the loading screen, it crashes with D3D12.

Here's a log where it eventually worked.

[JacobAL]

Doesn't seem to matter, crashes on starting a level anyway.

[JacobAL]

On further experimentation, it seems that LLVM causes the main issue with loading the game, whereas Interpreter PPU+ASMJIT will still work.

[zminhquanz]

This game have a freeze during boot when you using PPU LLVM

[JacobAL]

LLVM still an issue but the recompiled audio now works really well.

[RipleyTom]

I investigated and it's not a LLVM issue.
It's a sync issue caused by bad coding in the original game, only occurs with llvm because of the speed at which ppu runs with it.
I may release a patch for it at some point.

If you need for another version, contact me on discord.

[RipleyTom]

After discussing it with jarves and kd-11 we discovered a forgotten sleep(1ms) in the rsx thread.
#3158 should fix the issue with processors with a sufficient amount of cores.
The race condition is still there however and for processors with few cores this may still be an issue and the patch still needed.

Edit:
Just to be clear, the race condition is always there(because of the original game code, not the emulator), just less likely to happen the more cores you have.

[YaPeL]

How many cores are we talking about? X > 2?

[JacobAL]

Saw the video on the youtube channel today. I'll try the newest build when i have some time. Thanks for the fix!

[davoodinator]

can you make a patch for the NPUB31235 version as well please

[RipleyTom]

Added fix for NPUB31235, not tested but it should work.

[RipleyTom]

Added fix for BCAS20298 version

edit:
I had forgotten to update the offsets, done now sorry.

[SamuelBeckingham-Cook]

Still happening for me, hangs on the loading screen. Here's a link to the log

I have it set to Recompile GPU+SPU and Vulkan - Using the BLUS30767 version.

If I swap the GPU to Interpreter - I get slightly different behaviour. The "Now loading" message briefly fades, then this logs:
E {PPU[0x1000011] Thread (FiberFunc) [0x004a15e8]} cellSaveData: cellSaveDataEnableOverlay(enable=1)
And then it returns.

With LLVM, this happens faster than the loading screen can appear. EDIT: I have also included the patch.yml above - No luck unfortunately

Getting this issue where the game won't get past now loading any more. Not sure when this started but the last few versions I've tried are like this.

[AniLeo]

No real issue on your copy pasta

[JacobAL]

Not even all those things that say failed and the fact that it was all red? It didn't go past the first loading screen.

[AniLeo]

Maybe unimplemented cellNetCtlGetInfo and even that is not likely the cause, the rest is pretty normal. Most of the times the issue doesn't end up logged.

[JacobAL]

Loading liblvl2 only fixed it. Should troubleshoot before opening problems really.
