Strange glitch in Xenoblade/Last Story

Zecht · 02-08-2014, 12:39 AM #1

I have this bug a long time. I described it on http://code.google.com/p/dolphin-emu/issues/detail?id=6737

I tried 34\64 versions of Dolphin.

In Last Story i can get to menu no problem, but when i select new game i see a "square loading screen", hear some laughter and thats it. Dark screen and no life

In Xenoblade it almost the same - menu worked, but game freeze on New Game loading.

I have 2 other Wii games - Legend of Zelda Twilight Princess and Muramasa: Demon Blade - they work perfect. Gamecube games - also no problem.

So... any suggestions? I think problem related to sound and New HLE Engine merge around dolphin 3.0-900 something

PS. One more thing - when i select OpenGL backend i havу no image in games. Black screen, sound work and game seems to work also, but without image Smile

And when i return on Graphic Options screen Dolphin seems to lose my graphic card. like this:

At least two people couldn't reproduce the issue (and new games in XBC work just fine for me, so that makes three...) so it's probably a problem specific to something you're doing. Verify the integrity of your disc image. Right-click the games in Dolphin, go to Properties, head all the way right to Filesystem, right-click on the first thing you see there and check for an option that checks the disk's partitions (or something to that effect, I forget).

Any errors mean you have a bad dump, in which case you should dump your games again.

Well, i did not made up that problem after all Smile

Images are fine. I completed Xenoblade before (and tried it right now) on 3.0-71 with Xenoblade hack, and Last Story worked there too. So no, i don't believe that is the reason.

How can you say the images are fine without having checked them? The version of Dolphin you used had inaccurate emulation of several features; a bad dump may have been able to get away with Dolphin's past inaccuracy, but not now since Dolphin itself is more strict.

At any rate, are you using the old in-game saves from your previous Dolphin folder? Perhaps you should start clean and delete everything (keep backups though). I know some games like MKWii used to have issues saving unless the save data was deleted first, but I've never seen it crashing a game like this. Still, it's something to try.

Checked - all fine.

Deleted all configs and saves - no, same problem

Do a bisect then to narrow down which revision first introduced the issue into Dolphin then.

ok, checked... it was a lot of revisions Smile

Worked 3.5-556 Fix compiling Dolphin on devices that provide crazy GLES drivers
Glitch 3.5-557 Fixed issue 5270. Don't ask me how, I just clean up code and then it works! I think it was int overflow.

Update. Looked up issue 5270. Have a theory that problem lies in ciso format of images. Will try to convert into iso or wbfs

Good job

So the commit in question (https://github.com/dolphin-emu/dolphin/commit/33a13b1a37ab18ecbff43ed9224135602441348a) looks like it affects CISO stuff. Do you happen to have XBC as a compressed ISO? If so, you may have to report the issue (citing that .CSO will experience the problem). One solution then is to try using an uncompressed ISO.

Zecht · 02-08-2014, 03:30 AM #9

yes, our theory was right. CISO was the reason.

On that note i wonder - how many people have same issue? Maybe it will be better to disable CISO support in dolphin?
