Sonic and Shadow's Top Speed Upgrade Glitch.
Long name huh? Anyway, This is simple BUT you need to have ancient light(light attack) to pull this off. First try to get a speed up item (you can also get it when you pass through a checkpoint with 80-89 rings) as soon as the song starts use spin charge until you get the shiny lights floating. Like in 3/4 of the song the character should move normal again. After the song is over, let go of the b button and run in the longest flat surface you can find and test their speed. AND if you restart the speed stays like that, but it only wears off when you leave or complete the stage.
P.S.:This also works in Sonic Adventure DX Director's Cut.
