Arriving either before or during the release day of New Super Luigi U is a patch for New Super Mario Bros. U that will allow use of the Wii U Pro Controller. For those lacking in Wii Remotes, have used their GamePad for more than 4 hours, or simply prefer the Pro Controller, this should be rather exciting! Hopefully it’s not too late for all of your early adopters, then again, this patch will also be in effect for New Super Luigi U, so enjoy!
