|System: Sega Mega Drive|
|Original game: Sonic the Hedgehog 3 & Knuckles|
Sonic 2 Delta is a groundbreaking series of ROM hacks by famed Sonic scene member Esrael Neto, which restores several deleted levels and prototype elements to Sonic the Hedgehog 2 for the Sega Mega Drive. Various features of Sonic 2 Delta, common across the series despite the existence of several versions/branches of the hack, include the use of art and music from the betas and Sonic the Hedgehog and re-implementation of badniks that had been removed from the final game. The level order of Sonic 2 Delta is also similar to the original intended order, rather than that used in the final version.
The main version of this hack is entitled Sonic 2 Delta and was based upon the Simon Wai prototype, before version 0.24 transferred the codebase to ‘revision 2’ of Sonic 2 from Sonic Compilation and before version 0.29 transferred to the Sonic the Hedgehog 3 & Knuckles codebase. More information on the various lineages and their history is detailed in the section “Other versions” below.
The order of levels is directly as shown in the newly implemented Data Select menu:
- Green Hill Zone: Straight from Sonic 1!
- Marble Zone: From Sonic 1.
- Spring Yard Zone: From Sonic 1.
- Labyrinth Zone: From Sonic 1.
- Star Light Zone: From Sonic 1.
- Scrap Brain Zone: From Sonic 1.
- Final Zone: Also from Sonic 1.
- Emerald Hill Zone: Contains prototype layout elements, and the Coconuts Badniks are replaced with the scrapped Snail badniks.
- Winter Hill Zone: The graphics that are used are unlike any descriptions ever given of the winter level, other than the winter setting. Instead, graphics are extremely similar to Sonic Triple Trouble's Robotnik Winter Zone, with the layouts derived from the same zone. There are trees present but not Christmas trees. Also, no graphics from the (also scrapped) desert level are reused; this differs from the official team’s plans for it to be largely a palette-swap (similar to what Hill Top Zone is of Emerald Hill Zone). The BGM is that of 2 player Mystic Cave Zone and the boss used is from Sonic 1's Marble Zone.
- Wood Zone: The graphics are similar to what is seen in the Simon Wai prototype. It uses a slowed down version of the Emerald Hill 2 player music as its BGM. It reuses the ARZ Boss.
- Sand Shower Zone: Uses graphics similar to the mockup screenshot. It's a desert-only setting. The BGM used is from Oil Ocean Zone but slower. The boss of Emerald Hill Zone is reused for this level, with no alterations.
- Chemical Plant Zone: Small minor alterations were made, such as the loops having slanted corners, like in the prototype.
- Neo Green Hill Zone: Sonic 2's ARZ with its prototype name and music.
- Casino Night Zone: As mentioned previously, it has been reverted to its beta form.
- Hill Top Zone
- Dust Hill Zone: Sonic 2's MCZ with its prototype name and music.
- Hidden Palace Zone: The graphics are the same as those found in the Nick Arcade prototype, with a layout extending from said prototype. The BGM used is the same that was found in the final version of Sonic 2. A lift can be found on the long ramp; this was unused in the Nick Arcade prototype. This zone's boss is a near-perfect recreation of the Hidden Palace Zone boss from the 2013 Sonic 2 mobile remake.
- Oil Ocean Zone - 'beta style', with different music and the ride-able balls found in the betas.
- Metropolis Zone
- Genocide City Zone: The background graphics of Oil Ocean Zone are reused but in a night-time setting. The foreground also reuses graphics from Chemical Plant Zone. There is one act only, and the boss reuses Chemical Plant's boss.
- Sky Chase Zone
- Sky Fortress Zone: Uses the beta name.
- Death Egg Zone: Slightly different in that: A. You get 3 rings to start the zone, and B. The music is from the beta.
- Angel Island Zone
- Hydrocity Zone
- Marble Garden Zone
- Carnival Night Zone: Uses the music from the November 3rd prototype.
- IceCap Zone: Uses the music from the November 3rd prototype.
- Launch Base Zone: Uses the music from the November 3rd prototype.
- Mushroom Valley Zone: Uses the beta name.
- Flying Battery Zone
- Sandopolis Zone
- Lava Reef Zone
- Hidden Palace Zone (Sonic & Knuckles)
- Sky Sanctuary Zone
- Death Egg Zone (Sonic & Knuckles)
- The Doomsday Zone
