This is a demo game made by Simon Thomley that recreates a portion of Sonic 1 on the Game Boy Advance by reverse-engineering the original game. The proof-of-concept ROM was created in early 2007 as a direct counter to Sonic the Hedgehog Genesis, SEGA's official port of Sonic 1 to the Game Boy Advance.

The demo includes the entirety of Green Hill, the special stage, and a partially complete Labyrinth Zone. And it also brings playable Knuckles and Tails.

This project was later used as the foundation for two other proof-of-concept games: Sonic DS and Sonic CD DS.

Features

One-zone demo runs that smoothly at 60fps.
Sonic's spindash ability is fully functional.
Tails and Knuckles can be accessed by holding A or B and pressing Start at the title screen.
An incomplete Labyrinth Zone can be accessed by holding L at the title screen.
Debug Mode can be toggled by pressing R in-game, enabling object cycle and object placement using A and B.
