"Single Core" broken?

[elite]

I use r5081 x64 and also tried latest as of today, at least 2 games crash on startup when I DISABLE Dual Core mode. Is it known bug? Games I tried are House of Dead:overkill and my current Fire Emblem:path of radiance, there may be more. I had some issues in those games so I wanted try them with DC off and Dolphin always crashed on attempt to run.
Though I should let you know, I think this happened to me already before r5081. It was under D3D and Idle skipping both on/off.

I fixed this issue in r5118 for JIT and r5122 for JITIL.

It's been broken since r4854.

The issue is documented in issue 2053.

Skid, Single Core "SC" mode is still broken as of r5135 x64(JIT). It doesn't crash this time but I get no display at all although game is running and I can hear sounds. It happens in most of games I have: Fire Emblem[gc], Fire Emblem[Wii], Metroid 1,2,3, New Super Mario Bros, Silent Hill:SM, SMG, Zelda TP...
Zelda WW crash with opcode error.
The only game where SC mode works seems to me Dead Space.

It happened in the past that one revision made "SC" mode crash and with another I just got blank screen - switching every now and then.

When enabling DC mode, problems go away.
PS: It seems to happen in both D3D and GL.

Are the sounds repeating? or are they new sounds generated by the game but with no picture?

Does it hang at the same spot every time? or is a bit random?

Can you try to reproduce this bug with r4853?

Sound isn't repeating, game seem to run fine. I'll try that revision later my friend is by me now am showing him emu )
Btw, seems in r5081 even with DC on Metroid 1 crash when trying "new game" and text seems messy even with safe texture on, but I may need new topic about it its just now quick report. I'll be back. ^_^

EDIT: Don't mind Metroid, r5081 messed text in main menu but later made it correct again. It didn't crashed again.

Hey dude, am back! Indeed, r4853 runs all games with DC off fine.

Thanks for the report, elite. Would you please try one more test: check if this bug occurs in the x86 version too?

After that, please file a new issue in the issues list with all of the details from this thread.

Now that's weird - I've using single core mode all the time since dual core mode is strangely broken in the linux build - single core creates two threads both consuming 100% cpu for emulation while dual core mode spawns four of those threads effectively slowing everything down. (x86_64)

benpicco, there is a line in CoreParameter.cpp

Code:

bJITLoadStorePairedOff = true;

Can you change this to:

Code:

bJITLoadStorePairedOff = false;

and retest?

Ok skid, http://code.google.com/p/dolphin-emu/issues/detail?id=2379 - hope its correct. 32bit had same problem.
