There is no code to become Super or hyper Sonic.
No, you can not by Hyper Sonic in Sonic Rush. For Sonic to go Hyper, he needs the 7 Super Emeralds, which Sonic Rush does not have. The Super Emeralds were only in Sonic 3 & Knuckles, so Sonic can only go hyper in Sonic 3 & Knuckles.
Sadly he cannot, because Sonic needs the 7 Super Emeralds to turn hyper which are unavailable in Sonic Rush.
There Is No Code To Become Super Sonic Whenever You Want In Sonic Rush.
no
In Sonic Rush, Super Sonic only flies in space. He has no animations for doing several things, such as launching off of a spring, doing tricks, grinding, ect, so using him in a normal level would cause the game to freeze whenever you do something that Super Sonic can't do. So, no.
