Emulator

could this be the same issue that I just reported - issue 7938 (GFX FIFO Unknown Opcode in Resident Evil 0 Wii PAL)? I suppose jim51 has disabled Panic Handlers and therefore he does not see error messages, but the rest of it sounds the same.

Here is a link to a video of my issue, sorry it took me so long, I have never had to record PC gameplay before.

Turn on panic handlers

Panic Handlers are on.

Oh, that makes this a lot more interesting then. Maybe it's not a fifo issue? Can you try turning off any cheat codes? Can you verify your ISO MD5?

I don't have any cheats enabled hat I am aware of, not sure what "ISO MD5" is.

right click the game in the game list, go to the info tab, and grab the revision number and the verify the md5. Give us those.

I have taken several screenshots & attached them here. The last is the info you asked for.

Uh, click "Calculate" next to MD5 checksum? All your dumps are normal-size, so you've likely been dumping them properly yourself. Equal probability of it being a bad dump in either case, though.

This is what it gave me after computing:

So any ideas what is breaking it?

@jim51 Enable the checkbox "Show FPS" under Graphics Configuration.
Can you make a video and link to it and tell us your processor as well please?

Try single core mode; aka disable dualcore option in options/configure.

I tried single core mode, same results. I am running an Intel Core I7 4790 CPU @ 3.6 GHZ. Attached is a video with the FPS enabled. Not sure how well you can see it, but it mostly ran at 60 FPS.

Try turning off v-sync

I have ran it without V-sync as well, same issue.

As a test, would you please turn off "Ignore Format Changes", switch to EFB to RAM and turn off "Fast Depth Calculation"? This is to ensure that the issue isn't caused by one of the graphics hacks.

Would you also please take a screenshot of the Game Properties? Right click the game in the game list and select properties. It has a long list of check-boxes.

I have added screenshots of the settings as I have adjusted them per your request. Same thing happens.

Just noticed that the game is PAL but the FPS is running at 60fps. Would you please try enabling Progressive Scan under the Advanced graphics properties?

If that doesn't work, delete/move/backup the SRAM.raw file that can be found under the User/GC folder. This will clear the GameCube's internal memory where it stores information like progressive scan.

I enabled progressive scan, same results. Why would I delete my save files? i did not have progressive scan enabled before. When I first started the game it did give me memory card format errors twice.

The SRAM.raw does not contain your save file. It is the MemoryCardA.EUR.raw that has your save file. SRAM.raw is safe to delete as Dolphin will regenerate a new one for you. To be safe, you could back-up SRAM.raw first.

Deleted the SRAM.raw file, tried again with progressive scan enabled, same deal.

I'm running out of ideas, sorry. Maybe try updating the video driver or using the OpenAL audio backend instead of XAudio2.

I used OpenAL & same issues. Are there specific drivers for Dolphin? If so how do I update?

I meant the Nvidia video driver in Windows.

Checked, I have the most updated drivers.

Any other ideas? I played metroid prime 2 for a whole without the same glitch, can it possibly be a bad iso file?

It's not a bad .iso, we checked that earlier – your MD5 hash matches the one on redump.org: http://redump.org/disc/1247/

OK, so any other ideas?

Nothing in particular from me. I dunno exactly what's goin' on, and if it's FIFO stuff I bet we're gonna break yet another thing when we fix this...

Sorry, not sure what FIFO is.

But "versions of Dolphin used to work?N/A" what does it mean? That you didn't try other older revisions or that no one of them works for you?

That I did not try any of them with this recently. I daw the list of them & did not known which version/s to try. There are a lot there, not sure what's different with each.

Try to get back a hundred revision (for example 4.0-4565), if it still doesn't work try get back much more (500 revisions) and so on...btw you didn't overclock your system? Temperatures are under control?

Ok so I downloaded version 4.0-4503. I have been playing for about an hour & so far no glitches, seems to run smooth & the error seems to be gone. Thanks for all the help.

That's not the point of telling you to use an older version. We want to find out what version causes the problem so we can fix the bug!

ok, well i was running version Dolphin 4.0-4603 & it continuously gave me an erro when trying to play a game. SO thats the version with the bug.

What error? Is there a message? screenshot please on imgur.
That's not what you reported though.

Does using the version prior to 4.0-4603 have stuttering?
What version after 4603 stops the new error you're reporting.

Info -- we need it.

Can you try the latest dev version with "Skip EFB Access to CPU" checked?

The error I reported is listed above. The images are recorded in 2 videos also linked above.

Try in the latest development builds with XFB on.
