I know that Cars 2 isn't on the list of most wanted fixes but since I have kids who love the game I had to make it work so that they could play it and I figured that there are others who are in the same situation as I who can benefit from this.
I know that there is a Cars 2 fix released already but the only one that I have found is for the Eur BLES01328 version and when you apply the fix it defaults the language to German with no option to change.
I have fixed the US BLUS30725 version and just figured that I would add my working fix to the growing list of fixes for our site.
Here is the fix :
Cars 2 - BLUS30725

Just replace the Eboot and Param files with the ones from the fix.
Tested on Rebug, Rogero, and Kmeaw 3.55 CFW
