The game is markedly different than other Sonic games; aside from "improved" graphics and sounds, each level has 2 to 4 alternate versions that correspond to different time periods. Sonic can move between them to affect the gameplay and ending.

This run is approximately 37 seconds faster than upthorn and nitsuja's previous run thanks to various optimization and minor route changes. For more information on the improvements, the BIOS files used and a run for the Japanese version of the game, please read the author's submission notes.

There are two AVIs, the first recorded with the US music and the second with the Japanese music.
