There's a certain maneuver in Nitsuja's Route 99 1 video that I question. It's basically a double jump with boost mode added into the end. However, considering it probably wasn't intended to have that happen in the game, I bring this up to question.
The Nitsuja Trick (which I like to call it) is performed when Sonic is the partner. While Sonic is being held, pause the game, making sure not to hold A when you do. Let go of R, hold A, then unpause, and presto! Pretty simple trick.
However, the method makes me question if it should be used, though I can't see how it can be abused to an extremity.
