Sonic 1 Beta Remake is a Sonic 1 hack created by Mistergambit, first released on September 14th, 2006. This hack has all of the Sonic 1 levels redesigned to look like their prototype counterparts, as seen in various magazine screen shots. This hack also has new objects, such as a functioning Splats, the checkered ball that was scrapped from GHZ, and more. To make it seem more like a genuine prototype, some levels are made to look unfinished.

- Collecting a Chaos Emerald will cause Sonic to do a pose.
- Alternate ending with the unused Robotnik's death sequence.
- No credits screen, Screen says "COMING SOON" then goes to the SEGA Screen.
- Sonic punches the air when you press the jump buttons at the end of the level. (Thanks Tweaker)
- Press Start Button text on title screen.
- "TM" is removed from the title screen as Sonic wasn't trademarked yet.

- Sonic's pallete is different (blue-er).
- There are X's next to some things on Level Select.
- The level select is black and white.
- There is no Sega Sound.

- SYZ has been completely changed.
- SYZ has animated sparkles in the BG.

Clock Work Zone Act 3 (Final Zone)
- FZ is now a full act long and there is no boss. (only an eggprison)
- There is a machine present at the end of the level, which malfunctions as you push against it.
- No ending after you beat FZ.
- There is a tube which is hard to get past without debug mode on. (You have to spindash/roll the moment you enter the tube)
- There wheels that don't work near the end that are even harder to get past without debug (though using debug mode there are dots when placed on the wheels, will be fully functional).
- 005: Debug mode doesn't work, W posts in Special Stage act like R posts.
- 004: Debug mode does work, unused crumbling platforms are found in GHZ.
- 003: Title Screen Level Select/Debug mode, works the Same as the Final.
- 003B1: In Debug mode one space is empty, making Sonic invisible.
