Emulator

Change your graphics to OpenGL when entering. You should be able to switch back to D3d, but make sure to save frequently because it may crash during other room transitions. Cheers!

I've yet to see a crash in this game. Can you make sure you're not using 2GB or more of RAM when it crashes like this?

Similar unknown pointer dialog that I've posted about in https://code.google.com/p/dolphin-emu/issues/detail?id=7966 . I use OpenGL.

+1, though I get this crash right after the screen turns white following the title sequence after the Mario/Luigi scene near the start of the game. Both on OpenGL/Direct3D.

Neither of those options seem to help much on my end.

I don't see how this is related to bbox at all. All async querys like efb peeks or perf querys share the same issue.

I can't reproduce the issue when maintaining a stable framerate, so I'm really not sure why it would be failing.

By stable, I mean FPS and VPS being the same.

Actually, what's your GPU? There are two ways to get this problem, the second one is to have an Intel HD graphics card.

AMD Radeon HD 8650G + 8750M

The 8570M should be fine. Does the freeze happen on the same frame every single time?

From what I can tell, yes, the same frame.

Is this of any help?

You're hitting the "My graphics card doesn't support hw bounding box" crash that I usually blame on Intel HD cards. No idea why that Radeon can't do it though, maybe try updating drivers and whatnot?

I completely forgot to check with Direct3D after enabling GPU sync. It works.

Yeah, this crash happens if BBox isn't working correctly. Are your drivers up to date?
IIRC older AMD drivers were broken, newer ones are fine. Maybe it's just the same issue here.

Yep, you're right. Updating to Catalyst 14.12 fixed the issue in OpenGL. No need for GPU syncing enabled.

It's likely using your Intel HD. Try following this guide:

Or just use the intel HD GPU and update your (intel) drivers :P

Hey there,

This is the same person who posted before, just had to delete that comment because I realized I posted it on the wrong account!

I should have mentioned that I already configured Dolphin to be running on the Nvidia card, and the crash still occurs.

For completeness I updated my intel drivers, and tested the same problem on the Intel integrated graphics. The crash still occurs on Intel when using Direct3D, but fixes itself when I switch to OpenGL on Intel. (I also tested the GPU Synch/Single Core stuff while on Intel Direct 3D and that didnt seem to fix it). It still crashes while using the GT 650M with either OpenGL or Direct3D.

I'll blame optimus then. Try updating all drivers and whatnot. I can't reproduce any issue on a GTX 760 here.

I updated all the nvidia drivers and the Direct X Runtime and still hit the issue.

I was able to get around it by just disabling the bounding box for that segment (I dont even know what effect its trying to produce there, its not a fancy transition point), and so far havent had any issues since then (or before then). So maybe its just some random bug with that specific transition on 6XX series GeForce cards. (The fact that its the same pointer every time would make me think its not just some timing issue).

Anyways I have a save state right before the transition so I can reproduce it at any time if you want me to with more debugging information, otherwise just disabling it on that one transition seemed to work fine.
