Emulator

I'm sorry for my tecnological illiteracy, but how do I do that?

I get this issue to with the 4.0-4267 build (didn't try any others).

It seems to be an error with MSVCR120.dll according to the Windows Event Viewer:

Do you have enough disk space left?

I've been having this issue too with 4.0-5291 on Windows 8.1. The issue seems to happen every 5 or so isos. I've attatched the call stack when the error happens. It crashes in the specified function because m_rVolume is set to null when it tries to call its Read method.

I should note that Dolphin appears to finish the compression of the ISO successfully and the Compression progress box says "Done compressing disk image" and at that point the crash happens.

A few more things:
This issue goes back to at least 3.0-783.
This only happens with Wii ISOs.
When doing a batch compression, the dialog will display the previous ISO and "Done compressing disk image" when it moves onto the ISO that makes it crash.
When doing compression one-by-one, it will behave as shown in the video in the issue report.

Fixed by 4.0-7007
