FIFO is overflown by gather pipe cpu thread is too fast

[Edden]

Hello there, I was playing Battalion Wars on Dolphin and a few times now I get an error box that says something about FIFO is overflown by gather pipe cpu thread is too fast.

The thing is, I read something about that I can simply click Yes and it would ignore the error, but whenever this text box shows up, I'm unable to click ANYTHING on my computer, I can't click Yes, No or the other option in the box. To get the box to disappear, I need to open my task manager and end the program myself. It's frustrating because I can't play any more levels in the game.
It only happened in Battalion Wars before, I was playing Animal Crossing and Chibi-Robo, didn't get the error there.

Any help?

Try turning off dual core.

Worked! But while dual core is turned off, I can't use cheats in the game, they're selected and activated but don't seem to take action.

It should be in the first tab that shows when you click on the "Einstellungen" button.

the label should be called "Dual Core aktivieren (Beschleunigung)"

(I just searched through the translation files, best I can do without screenshots. Don't have dolphin on this PC)

Please answer to my last message, I'm not able to use cheats anymore, what do I do?
