.sav file corrupted on Mario Bros

I've got a corrupted .sav file on Mario Bros... I've deleted the game, downloaded a new one and copied it over twice.. but still get the same message. No problems with any other games just this one.. Using R4/ Can anyone help?

Well...delete the save file and see what happens.That may help. It should work on ALL flashcarts.

Update your r4.

If it's Mario and Luigi: Bowser's inside story, it's probably something to do with the anti-piracy. There are loads of threads on it in the Technical Help forum. Try searching there.EDIT: I guess it's not Bowser's Inside Story, seeing as you didn't try my idea.

I've already deleted the .sav file and the game file two or three times.. but I will update the R4 software see if that helps.
Thanks
