Release 4 (2019)
The 4th release Sonic 2: Advanced Edit was released as part of the 2019 Sonic Hacking Contest, with a final bugfix release planned later.
It features 7 entirely new Zones, each full of unique enemies and with a boss whose gameplay varies depending on the player's character. Playable characters are Sonic, Tails, Knuckles and Amy. Furthermore as bonus content, the hack features the 5 Zones from the 2008 release, brushed up to be fully playable. Upon completing the 7 main Zones, the player obtains a code to access the level select from which they can play the bonus Zones by selecting "South Island 1". There are 69 Giant Rings scattered throughout the 7 main Zones. Collecting 7 of them will grant the ability to turn Super once the player has at least 50 Rings in any given level.
The hack has been about 10 years in the making, with very little progress in the last few years due to real-life commitments and rika_chou and qiuu as the only remaining contributors. Many aspects are not exactly as envisioned due to limited time, but it was decided to push for a final release to make the development not continue indefinitely, with the risk of never being released at all.
- Sonic, Tails, Knuckles: Same as in Sonic the Hedgehog 3 & Knuckles. (No Spin Dash for Tails.)
- Amy: , +: Hammer attacks; /, +/: Jump/Spin Dash.

Release 3 (2008)
The 2008 release features 3 new levels. Other (incomplete) levels can be accessed by using the level select menu.
Release 2 - Known Issues
- If Sonic enters a Special Stage with a Lightning Shield then exits again, the shield is gone but the ability to drain rings is still effective.
- When running at high speeds in Roof Top Zone, Sonic occasionally passes through solid walls.
- Sonic's starting sprite is corrupted in Robotic Ruin Zone.
- In Robotic Ruin Zone, there is a rather large secret area containing several elements from the original game's Metropolis Zone. Rings are scattered in very strange places, and there is a long tract of what seems to be lava throughout one half. Once the player gets into this area, s/he cannot leave without restarting. (To access this area, find a thin strip of lava next to a pit containing four yellow springs. Jump into the pit and push to the left, then fall down the lava; You should reach the hidden area.)
- When becoming Super Sonic, Sonic's sprites do not coincide with his sprites from Sonic 3. The result is an amusing disconnect between his movement and his speed.
It is important to note that neither Tails nor Knuckles can access their super forms.
