Can't Play New Super Mario Bros. Wii

[PianoDude1011]

So recently I haven't been able to play on New Super Mario Bros. Wii on my Lenovo G505s (Link: http://www.newegg.com/Product/Product.aspx?Item=N82E16834313719&cm_re=lenovo_g505s-_-34-313-719-_-Product). I have 8GB of RAM, not 6, but otherwise the specs are the same. It was working fine until suddenly, whenever I go into a level, it says, "Dolphin.exe has stopped working...Windows is searching for a problem to the solution." You know, that nonsense. Tried it over and over, same result. I'm using a Dolphin Dev version. I have no clue what dev version I'm using, how do I check?

The window title says wich build you´re currently using (when opening dolphin, just look at the top). It may also your game´s ISO being corrupt.

I'm using Dolphin 4.0-1516
ISO isn't corrupt, I've been using it for...forever
EDIT: It's only one level I can't get into. Any way I can patch that or something?

Change the audio backend from Xaudio to another one.

It sounds like a bad ISO to me as well.
