What's the problem? Describe what went wrong.

In Sonic Adventure 2 Battle, when you save the game, exit Dolphin and start it again, the game says that the save file is corrupt and has to be formatted.

What steps will reproduce the problem?

It seems to happen quite randomly, but the game file will corrupt after finishing some stages.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

This issue seems to apply only to Dolphin 4.0. I tried it on several dev builds. On Dolphin 3.5, this issue doesn't happen. The game saves normally and the
save file doesn't corrupt.
