How do you transform into hyper sonic in ssf2?

In Super Smash Flash 2 (SSF2), transforming into Hyper Sonic involves using Sonic and executing a specific series of inputs. First, you need to collect all seven Chaos Emeralds by playing through the game. Once you have them, press the special move button (usually Down + B) while in the air to trigger the transformation. This grants you enhanced speed and abilities for a limited time.
