How it works

This Sonic Speed Simulator speed boost script modifies your character's speed values in real time, allowing you to move significantly faster than normal. It works by injecting commands that enhance acceleration and top speed parameters while the script is active.

The script also manages cooldown periods between boosts, often reducing or bypassing them so you can maintain a continuous high-speed run. You toggle the boost with a keybind, making it easy to control your speed during races or exploration.
