SSB: Brawl. Supspace Emissary 31% crash.

[ares]

Hello,

After beating giant diddy kong in the supspace emissary campaign the game crashes. (This is at 31% of the campaign.)

exceptioninfo.txt:

Code:

Unhandled Exception
  Code: 0xC0000005
Call stack info:
     Dolphin!0x00000000 : ?
     0x159F1000 : ?

I'm using the PAL version and to prevent configuration questions. I use my own configuration but for this crash I also tested using the configuration explained in this post. The computer hardware can't be the problem either as I tested in on 3 different computers:

• AMD, 1 processor, old NVIDIA video card, win xp
• Intel, 2 processors, average NVIDIA video card, win xp
• Intel, 4 processors, good NVIDIA video card, win vista
  

I'm quite new to Dolphin but based on the information I found in the forum we need a patch to fix the invalid memory address. I have experience with debuggers but not with dolphin.

Someone has already fix this crash?
Someone is capable if writing the patch?
Someone is capable of sharing information about dolphin debugging so I can continue on my own? (or link to information which I have not found [yet])

Thanks,

Raymond

ps. Dolphin SVN R 3089

Yep, that is a known issue. I have the same problem, crashes right after the giant Diddy Kong. It is possible to go beyond that cutscene if you run the emulator on Interpreter Mode. TO run the emulator on interpreter, run it on debbuger mode and unselect every option in the emulator's configuration ( Idle Skipping, Dual Core, HLE the BIOS, Enable JIT, etc..)

The game will run extremly slow but you are able to go past the cutscene. If you want to try this yourself, i suggest you use savestates. Anyway, using this method does not avail you much, since the game will keep crashing in the next level, rigth before you reach a chasm. You can also use interpreter mode to go past this point, but the game will hang a bit farther ahead, even in interpreter mode (at least for me).

Regardin your question of sharing information about dolphin, you can access dolphin's source code by going to:

http://code.google.com/p/dolphin-emu/source/list

As you can see, the emulator recieves new updates many times a day, so I wouldn't be surprised to see this problem fixed soon. If you want to contribute, I sugest you get the source code and analyse Dolphin's core files. Once you have reached a solution, contact the developers =)

If I had some PowerPC knowlage and more programming skills I would try to do it myself xD

Well the problem is something is causing an access violation(0xC0000005)
I would debug it but i don't have SSB Brawl.

AlphaEndgame, thanks for the information and the link.
death-droid, I tried but I fail to set a BP add the right location.
