|System: Sega Mega Drive|
|Original game: Sonic the Hedgehog 3 & Knuckles|
Sonic Delta 40 Mb (formerly 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 Delta 40 Mb, 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. Several original boss fights have also been created for the hack.
The main version of this hack is entitled Sonic Delta 40 Mb 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: This, like most of the rest of the Sonic 1 zones, is entirely unchanged from its original appearance.
- Marble Zone: UFOs from the Sonic 1 prototype appear in the background.
- Spring Yard Zone
- Labyrinth Zone: Uses the prototype background and decorative elements.
- Star Light Zone
- Scrap Brain Zone: Act 3 uses Labyrinth Zone's prototype decorative elements.
- Final Zone: 3 rings are provided at the start of the zone, and the end of the zone is now a cutscene instead of being user-controlled. Additionally, after the score tally, Tails will fly in on the Tornado, and a unique cutscene will play that shows the Death Egg blasting off while Tails and Sonic fly to Emerald Hill.
- 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 a 16-bit recreation of Robotnik Winter Zone's music, and an original boss fight has been coded for it.
- 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 also has an original boss fight.
- 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: Aquatic Ruin Zone 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: Mystic Cave Zone with its prototype name and music.
- Hidden Palace Zone (Sonic 2): The graphics are the same as those found in the Nick Arcade prototype, with a layout extending from said prototype. The options menu lets you pick the music, either being the unused music found in the final version of Sonic 2 or the Mystic Cave 2 player music. 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 (Sonic 2): Beta music is used, and 3 rings are present at the start of the zone.
- Angel Island Zone
- Hydrocity Zone
- Marble Garden Zone
- Carnival Night Zone: The options menu lets you pick between using the final version of Carnival Night Zone's music, or the music from the November 3rd prototype.
- IceCap Zone: Options menu lets you choose final version music or the music from the November 3rd prototype.
- Launch Base Zone: Options menu lets you choose final version music or the music from the November 3rd prototype. Sonic and Tails do fight the Big Arm, like in Sonic 3 alone.
- 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): At the start of the Kyodai Eggman Robo boss fight, 3 rings are provided.
- The Doomsday Zone
Version 0.68 introduced an options menu, which primarily lets you switch different music options in the game as listed below:
- Sonic 2 invincibility theme: applies to all invincibility monitors in the Sonic 2 and scrapped beta stages, you can choose from the final invincibility music in Sonic 2, the prototype music (which is also the final Super Sonic music), Sonic 3's invincibility theme, or the Super Sonic music from the Sonic & Knuckles Collection.
- Sonic 2 super theme: applies to super transformations in the Sonic 2 and scrapped beta stages, you can choose between the final super music, the Sonic 2 and Sonic 3 invincibility themes, or just to continue playing the level's music.
- Sonic 2 boss theme: applies to all boss fights in the Sonic 2 and scrapped beta stages, you can pick between the prototype and final versions.
- Hidden Palace Zone: applies to Sonic 2's Hidden Palace Zone, you can pick between prototype (Mystic Cave Zone's 2-player music) and final (unused in final Sonic 2) music.
- Sonic 3 invincibility theme: applies to invincibility monitors in the S3&K zones, you can pick between Sonic 3, Sonic & Knuckles, and the prototype invincibility music.
- Sonic 3 super theme: applies to super transformations in the S3&K zones, you can pick between all of the Sonic 3 invincibility music options or to just continue playing the level's music.
- Sonic 3 mini boss theme: applies to all Act 1 bosses, you can pick between the prototype and final music.
- Carnival Night Zone, Icecap Zone, Launch Base Zone: each individual option allows you to pick between prototype and final music.
- Knuckles's theme: you can pick between Sonic 3, Sonic & Knuckles, and the prototype theme.
Additionally, the options menu includes special credits for everyone who contributed to the hack; access to the "Get Blue Spheres!" minigame that's seen when locking on Sonic 1 to Sonic & Knuckles; and a sound test that includes music arranged from several Master System Sonic games, the Sonic 3D Blast boss music, and the Virtua Racing menu (the lattermost of which is also the music that plays upon opening the options menu). This sound test is where you can enter in cheat codes (Level Select is 1-9-9-1-0-6-2-3, Debug Mode is 1-9-9-2-1-1-2-4, All Chaos Emeralds is 1-9-9-4-0-2-0-2, All Super Emeralds is 1-9-9-4-1-0-1-8, and Bridge Zone is 1-9-7-7-0-9-0-5). Once you enter the Bridge Zone cheat code, its music will play and the Play "Bridge" option will appear below the sound test, allowing you to play both acts of Bridge Zone.
The "latest version" is definitely out of date. For the most up-to-date version, go to the official website.
