Sonic Delta, also known as Sonic Delta 40 MB, Sonic Delta Next, and Sonic Delta Origins, is a Sonic the Hedgehog 3 & Knuckles ROM hack by Esrael Neto. The game serves to combine the entirety of the main four Sonic the Hedgehog titles from the Sega Mega Drive (Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic the Hedgehog 3 and Sonic & Knuckles) along with restoring various prototype elements that were seen in those game's respective prototypes.
The version number of Sonic Delta began with an earlier form of this ROM hack, Sonic 2 Delta, based upon the "Simon Wai" prototype of Sonic the Hedgehog 2. The switch to using Sonic 3 & Knuckles as a base began with Version 0.29, adopting the Sonic Delta name with Version 0.31.

Gameplay
Sonic Delta serves to present a unified Sonic the Hedgehog gameplay experience. Using the save feature from Sonic 3, players can choose to control Sonic the Hedgehog, Miles "Tails" Prower, Knuckles the Echidna, Sonic and Tails, or Knuckles and Tails. The character sprites are taken from Sonic 3 & Knuckles, along with each character's unique move set. The game's HUD is also based on the one from Sonic 3 & Knuckles, with two distinct modifications. The first is the timer, which includes milliseconds, as is done in Sonic the Hedgehog CD. The second is the Ring counter, which not only shows how many Rings the player has at a given time, but shows how many Rings exist in the entirety of the level. An extra addition to the HUD appears when a player reaches a boss encounter. On the bottom of the screen, a life bar appears for the boss, along with its name.
To match the stages from Sonic 3 & Knuckles, act transitions have been added to the zones from Sonic the Hedgehog and Sonic 2. Depending on how the acts are laid out, this may involve a wall to hide a background position shift, a short section before the official level starts to get Sonic to a different starting position, or simply placing the two acts next to each other. Transition cutscenes between levels have also been added, with two exceptions: the transition between Wood Zone and Chemical Plant Zone, and Aquatic Ruin Zone to Casino Night Zone.
If all seven Chaos Emeralds are collected, each character can activate their Super form. If the seven Super Emeralds are collected, they can activate a Hyper form.
2 Player VS
Two different 2 Player modes are available in Sonic Delta. The first is an expanded version of the 2 Player mode found in Sonic the Hedgehog 2. Player one can be toggled between either Sonic or Knuckles, while player two is always Miles "Tails" Prower. The original four 2P stages from Sonic 2 are featured: Emerald Hill Zone, Mystic Cave Zone, Casino Night Zone, and the Special Stage. Joining these four are Labyrinth Zone from Sonic the Hedgehog, Bridge Zone from the 8-bit version of Sonic the Hedgehog, Hill Top Zone from Sonic 2, and the exclusive Winter Hill Zone. To allow their inclusion, Labyrinth Zone does not feature any water, nor does Hill Top have its animated background.
Just as in the original, players are judged by five criteria: Score, Time, Ring count at the end of the Act, Total Ring count (including those lost by being hit), and number of Item Boxes popped open. The player that wins the most out of those five takes the round. Also included is the option to compete with all available item boxes, or to only have teleportation item boxes.
The second 2 Player Mode is "Sonic 3 VS," which is the competition mode from Sonic the Hedgehog 3. All stages and characters are carried over from the original.

Bonus and Special Stages
Bonus stages are entered in a similar manner as they are in Sonic 3 & Knuckles. When a player touches a Star Post, a circle of stars appears over the top. Jumping into the circle before it disappears, the player is warped to one of four different Bonus Stages. Which one a player is taken to is based on the amount of rings they have divided by four.
There are also two different types of Special Stages available. New to the stages of Sonic the Hedgehog and Sonic the Hedgehog 2 are Giant Rings hidden somewhere in each act. Non-boss acts, with the exception of Scrap Brain Zone Act 2, have at least one Giant Ring hidden. By finding one and jumping into it, the player is warped the the half-pipe Special Stage from Sonic 2. Collecting all seven Chaos Emeralds allows the player to transform into a super form. With the transition to Sonic the Hedgehog 3, the player must once again recollect the Chaos Emeralds by finding the Giant Rings hidden in those stages, as is the case with the official release.
