Emulator

On Linux dolphin can load both GC and Wii games saves.

I didn't say I was trying to open save states between different versions. Here's what I did to test:

1. Open version of Dolphin.
2. Load game (in this case, I tried Wind Waker and Mario Sunshine)
3. Save a fresh state using the new version
4. Wait 5 seconds to make sure it finishes
5. Attempt to load the state
6. Crash

You guys are quick to dismiss issues... Please reopen it, as this is a valid issue.

Until you give more instructions on how to reproduce it, it's not valid.

How much more detailed can I get with the steps to reproduce?

I don't know, figure it out. Save states work just fine for me, and apparently everyone else.

So, you think it's all in my head?

The system it's crashing on is a 2010 Mac Pro running OS X 10.8.2. I'll attempt to reproduce the issue on my Macbook Pro and Mac Pro at work when I get there, but I think it's a little premature to dismiss my issue as if I don't know how to save/load a save state.

This issue's valid, save states are legitimately broken on OS X right now.

Could you find the first revision that caused this issue?

I'm on it (same person that entered the ticket, but I logged in with the correct Gmail account this time...

Got it:

Dolphin Versions Tested
3.0-883 - Not working
3.0-863 - Not working
3.0-800 - Not working
3.0-750 - Not working (no overwrite error message, but loads still crash)
3.0-700 - Not working
3.0-687 - Crashes - Description: OSX build fix for BPStructs. Thanks to pauldacheez for the fix.
3.0-655 - Works
3.0-651 - Works

Between versions 655 and 687, the OSX build was failing... so there isn't one between then. I'm working on the overwrite error message version, but I'll enter a new ticket for that.

(On a side note, the overwrite error message is fixed in the most recent build, so I won't be entering a ticket for it.)

I have the exact same issue on OS X 10.8.2, as well.

I believe this issue is being caused by a disregard for OpenGL's thread safety (or lack thereof).

When the state is being restored in DoState(), a direct call to the renderer object is being made, which is doing it's own GL calls, which then crashes the program (any GL calls cause a crash). Non-thread safe behaviour is implementation defined, and in this case, Apple have decided that this should cause a null pointer dereference.

I'm yet to go back to the source for 3.0-655 and see why that works.

Thanks,

I just tried it... it still crashes.

Could you try this version: http://dl.dolphin-emu.org/builds/dolphin-osx-savegame-fix-3.0-900.dmg

It works!

That fixes it for me as well. In attempting to find the problem I noticed it only freezes when the first load is not paused. After that all loads work paused or not.

donaciano: Can you please attach a stack dump while freeze? I suspect to be an other bug ...

lawsonculver: Are you also affected by this bug?

From what I can tell, donaciano was only seeing crashing before the fix. Everything is working fine for me, and I've used save states dozens of times with a couple of different games with no trouble.
