Sonic Adventure DX Director's Cut Glitches

Knuckles and Eggman
Can be done by: Tails, Sonic, Knuckles and E-102 Gamma
Upgrades needed: Jet Anklet (For Tails)
Progress in story needed: You need to start Super Sonics Story

Do the "Tails at the Master Emerald" glitch (FOR TAILS ONLY) then go over to where Knuckles and Eggman where in the cutscene in Super Sonic's story and they will still be there! This is very weird with Knuckles! Also with Knuckles, when you move a different movement (Up, Down, Left and Right) next to the other Knuckles his head will move. There are three movements, Head faceing floor, head facing towards the camera and he will also face towards the sky.
