Error when starting Dolphin emulator in Launchbox: "IOS_FS: Failed to rename temporary FST file"

[vince16]

Hi everyone,

I've been having this problem ever since I started using Launchbox a year ago: when using the Dolphin emulator to play GameCube and Wii games, as the title suggests, a window titled "Question" pops up and it says "IOS_FS: Failed to rename temporary FST file". The game then usually starts after I press "OK" (sometimes I have to click a couple of times), albeit windowed ofc, as is inconveniently always the case with the Dolphin emulator. But I always get this annoying message starting the emulator in Launchbox, and ONLY in Launchbox. When I start Dolphin (it's the standalone version I'm talking about btw, not the RetroArch core) normally, i.e. not from within Launchbox, I never get this error message. But It's always bugging me in LB when starting Dolphin, be it for a Gamecube game or a Wii game

I also never get this message with any other emulator, be it started from within Launchbox or not. The PS2 emulator for example, opens and closes fine, even in LB.

I don't understand the meaning of this, what "FST" refers to, or "IOS_FS". I'm playing on a Windows 7 64-bit PC by the way, not some Apple computer running on IOS or w/e. 

Any help to resolve this problem would be greatly appreciated.

 

Edit: As I thought there was something odd when I started it again a couple minutes ago: something was missing. It only gave me the "IOS_FS: Failed to rename temporary FST file" error when it would usually give me another error after that, which I just got right now, so I'm adding the following. It then adds a window that says:

"Question" (the name of the error window) "C:\Users\vincent\Documents\Dolphin Emulator\Wii\title\00000001\00000002\data\play_rec.dat could not be opened! This may happen with improper permissions or use by another process" "Press Y to make another attempt"

As it turns out, I have to click "ignore for this session", but I get a black screen, and Dolphin doesn't respond anymore, if I try to shut it off I get the message "Dolphin has ceased to work" or something.

I absolutely NEVER get this when using Dolphin outside of Launchbox!

Hi @vince16,

While I've never seen this issue before when using standalone dophin with LaunchBox, some google searching seemed to bring about a lot of info of different people getting the same error message.

Since you seem to only be getting it from launching a game into dolphin from within LaunchBox (definitely confirm this, just in case), most may not be relevant, but worth a look:

• Make sure you are not running LaunchBox (or Big Box) as admin, this can cause a lot of issues, one of which is folder/file permissions issues.
• Some people seemed to indicate that it was their anti-virus program blocking their version of dolphin.
• Some people say it was their location of the Wii nand folder causing the error. Changing its location solved their issue.
• Could be related to a general folder/file permissions issue to where Dolphin places your user config files (usually in Documents inside of a folder called Dolphin Emulator).
• You could have file corruption issues within your Dolphin Emulator folder.

Yes I confirm it.

Thanks for the heads up.

-I am in fact running LB/BB as Admin, I had to set it that way, otherwise Windows Firewall gave me hell and wouldn't let me use Supermodel (Sega Model 3 emulator) as it had decided it was a supposedly dangerous software.

-I'll make sure Avast is not the cause of this too. 

-Could it be due to the fact I mistakenly installed Dolphin on C:\ while the GC/Wii ISOs are on E:\?

-Don't know what to do about that

-I somehow doubt it as Dolphin runs flawlessly outside of LB. Even if that's the case, I don't know what to do about that either.

 

Thanks for your help!
