Error loading only a few games

[MaLDo]

With newer versions of Dolphin I have a rare error. When loading some games, this message appears

"The specified file "C:\....\game.iso" doesn't exist."

and the game doesn't load.

* Only happens with some gamecube games.
* Path and name file doesn't affect the problem.
* Older versions of Dolphin load those games without problems.
* If I select the folder as iso folder, those games don't appear in the dolphin main game list.

Some of games that don't load

- F-Zero GX
- Starfox Adventures
- Starfox Assault

Gamecube games that work without problems

- Metal Gear Solid Twin Snakes
- The Legend of Zelda Wind Waker
- Super Mario Sunshine
