Roll left/right in New Super Mario

[quaxon]

Hi i cant figure out how to get the roll left/right buttons working. i can map them to the controller but they dont do anything when pressed. Using newest build 7681. It wasnt much of a problem till world 7 where i need the ability to be able to do one of the levels. any idea on how to get it to work? I searched everywhere since last night and havent found an answer.
