How to unlock the MannyMania achievement in Shaun White Skateboarding - Definitive Guide
USE THE METER AND YOU CAN GET THIS IN THE FIRST 5 MINUTES!!!
To manual in this game you hold the button and up or down on the left stick. To make this easy, go to the settings menu and make sure the balance meter is turned to on. With that you get a Green/Red indicator of how well balanced you are and that makes this super easy. It is easiest to do this on an incline going down (Downtown is great) but it's also easy on flat ground. If doing it on flat ground gain speed first and make sure you are in an area where you won't run into stuff. I did this right outside of the skate park just going in circles around the middle part of that area.
You can do this at any point in the game, however I found it easiest to do during the “Manual” challenge on Rising Island. The hill here is very steep and gives you a lot of speed, which makes it easier.
