When it crashes to the debugger, is there anywhere you can get a stack trace?

It should look something like the screenshot here:

How can I generate stack traces on PPSSPP? I have Microsoft Visual C++ 2010 but I know it can be done easier/more minimalisticaly. Do the normal builds support stack traces or I need to build from source with different parameters?

[[Unknown]]

You just need to build it so you have a .pdb file. Then, the easiest way is to run with Visual Studio (press F5) and when it crashes, it'll show the stack trace in one of the boxes on screen.

I tried using DDMS to grab the stack trace of the app when it crashes, but because it just crashes instead of force closing, no traces or dumps are generated, and method profiling in DDMS/Eclipse just stops when the app crashes without generating the .trace file needed. I read the logcat again, and the app seems to be trying to access an invalid memory address or some read-only memory, so the OS is throwing a segmentation fault (the SIGSIEV at the end of the logcat) and then it kills the app.

As for the Java Stack Trace Console option, the logcat is not actually showing a "Caused By" error, so it can't be put into the stack trace console to find the offending code. It's probably going to need trial and error to track down exactly what is causing the problem. For now, all that is known is that attempting to progress past the first dialog prompt/menu makes the emu attempt to work with some protected memory, of which the OS detects and throws a segmentation fault.

Here's a stack trace of a crash I'm getting from 1097(Windows):

Code:

>    PPSSPPWindows.exe!EmuScreen::render() Line 276    C++
    PPSSPPWindows.exe!ScreenManager::render() Line 87    C++
    PPSSPPWindows.exe!NativeRender() Line 417    C++
    PPSSPPWindows.exe!Core_RunLoop() Line 129    C++
    PPSSPPWindows.exe!Core_Run() Line 172    C++
    PPSSPPWindows.exe!TheThread(void * x) Line 82    C++

All I did was try to run the game, skip the intro FMV(it's black anyway), and then it's loading with an animated GT logo.

Unfortunately, that's all it's showing me(related to PPSSPP, that is, unless you want to see the ntdll.dll and msvcr100.dll calls too..).

[[Unknown]]

Hmm, that's `mipsr4k.RunLoopUntil(nowTicks + blockTicks);`. Does it crash with the same trace even with jit off?

Now it seems to be crashing in a different place as of 1140:

Code:

>    PPSSPPWindows64.exe!sceKernelChangeThreadPriority() Line 2277    C++
    PPSSPPWindows64.exe!CallSyscall(unsigned int op) Line 468    C++

Interpreter crash:

Code:

Ah, that's useful. Should be fixable, let me try.

Okay, this may hopefully fix that, would like to know if it doesn't / if it's still broken later and where:

Can be moved to In-Game, did a whole race to be sure.
It seems to work now but it has 2 bad glitches:
1. The font just repeats the first letter of the message, so if it's "Saving..." it will show "Sssssssss". Also if the message is something that scrolls into the screen it will start scrolling from the first to the next letter:
Example, "Saving..."
1st frame "Sssssssss"
2nd frame "Aaaaaaaaa"
3rd frame "Vvvvvvvvv"
4th frame "Iiiiiiiii"
...

2. Which is kinda gamebreaking. It will freeze if you have a savegame.

Does the font issue go away if you disable the vertex cache?

Does it freeze the same way with a savegame from a real PSP? What does the log look like without a savegame?

Nope, doesn't seem to affect it at all.

Yep. It has a mearure that you can load savegames only with specific nicknames, my PSP has the same name as in my ini but still it could be something related to that.

What part should I load to post it here? Like, just the menu, which is the part just after the freeze if you have a savegame.

[Donel]

Wow, I can't believe this game is going in-game right now. I've tested it and noticed the following bugs:

- The most obvious, the fonts are all messed up
- The rear view mirror is broken, just like in Ridge Racer 2
- The sound transitions as you change the camera are very abrupt. The music and the engines don't sound perfect to me, but I'm not quite sure.
- The 3D parts of the screen shakes like an interlaced game on PCSX2.
- Some visual effects are probably broken, as the game looks very empty
- The opening CG doesn't play at all

Other than that, it's working pretty well. The speed is adequate, but improvements in this area are definitely possible.
