SONIC DELTA 40Mb (Sonic Delta Next)

By Neto

This hack is a junction of all classic MD Sonic (Sonic 1. 2, 3 and Knuckles ) in to a single game. The games run over Sonic & Knuckles engine and use two custom sound drivers derived from S2B and SK sound drivers to manage all musics and effects.

This hack as title said has 40 Megabits of capacity, and was coded following SEGA Standards for games larger than 32Mb which require banking switch scheme to access extra data ( Flat coding is more easy, but the game will not work on all hardwares, especially with systems equiped with SEGA CD ). Since this hack uses banking switch scheme, with proper cartrige hardware you can run in all consoles without any conflict.

The Game can run in an ATGames Firecore console equiped with SDCard, but save feature will only work if you run the game through "Neto MD-DOS 1.10 or higher" in that console. ( https://www.neto-games.com.br/neto_md_dos/neto_md_dos.php )

The game has approximately 37 Levels, The number can be less, depending of the character chosen..

The Level Order is:

  • Green Hill (Sonic 1)
  • Marble (Sonic 1)
  • Spring Yard (Sonic 1)
  • Labyrinth (Sonic 1)
  • Star Light (Sonic 1)
  • Scrap Brain (Sonic 1)
  • Final (Sonic 1)
  • Emerald Hill (Sonic 2 Alpha)
  • Winter Hill (Sonic Triple Trouble Robotnik Winter Port)
  • Wood ( Sonic 2 Beta )
  • Sand Shower ( Custom Level )
  • Chemical Plant ( Sonic 2 Beta )
  • Neo Green Hill ( Sonic 2 Beta )
  • Casino Night ( Sonic 2 Beta )
  • Hill Top ( Sonic 2 Alpha )
  • Dust Hill ( Sonic 2 Beta )
  • Hidden Palace ( Sonic 2 Beta )
  • Oil Ocean ( Sonic 2 Beta )
  • Metropolis ( Sonic 2 Beta )
  • Genocide City ( Sonic 2 Alpha )
  • Sky Chase ( Sonic 2 )
  • Sky Fortress ( Sonic 2 )
  • Death Egg ( Sonic 2 )
  • Angel Island ( Sonic 3 )
  • Hidrocity ( Sonic 3 )
  • Marble Garden ( Sonic 3 )
  • Carnival Night ( Sonic 3 )
  • Icecap ( Sonic 3 )
  • Launch Base ( Sonic 3 )
  • Mushroom Valley ( Sonic & Knuckles )
  • Flying Battery ( Sonic & Knuckles )
  • Sandopolis ( Sonic & Knuckles )
  • Lava Reef ( Sonic & Knuckles )
  • Hidden Palace ( Sonic & Knuckles )
  • Sky Sanctuary ( Sonic & Knuckles )
  • Death Egg ( Sonic & Knuckles )
  • The Doomsday ( Sonic & Knuckles )

Nine Bonus Stages (six Sonic 1 Special Stages as Bonus Stage) which can be accessed by touching a lamppost with 20 or more rings. The formula for selecting which Bonus Stage will be played is "RING" count divided by 4 and the remmainder of operation will give the stage to be played:

  • 0 - Slot Machine;
  • 1 - Glowing Spheres;
  • 2 - Gumball Machine;
  • 3 - Sonic 1 Special Stage.:

You can play as:

  • Sonic and Miles;
  • Sonic Alone;
  • Miles Alone;
  • Knuckles and Miles;
  • Knuckles Alone.

All Characteres have Super and Hyper Forms. For Miles the Super Form has no flickies. In Sonic 1 and Sonic 2 part you will play Sonic 2 Special Stages through big ring (50 rings or more is required ) at end of levels. After Knuckles steal your emeralds in Angel Island you need to get all Emeralds again, now through S3 Special Stages.

Extra:

  • Debug object list works for all levels;
  • Demo mode edited to show some Sonic 1 and Sonic 2 Levels;
  • Options menu where you can personalize some sound tracks.

Hints:

  • If you are running debug mode to test, when Sonic is an object, hold "A" then press "C" to backwards the objects list. You can select the Egg Prison to skip that level.
  • The Perfect Bonus in the Sonic 2 Special Stage is given if you do not hit any bombs and complete the stage (You must protect Miles too in the cooperative mode).
  • If you use Save State in emulators for Sonic 1 and Sonic 2 levels probably the game will crash after the Save State is loaded. This occur because emulators does not save the SEGA Mapper state. To get the Save State working just start a New "No SAVE GAME" and after the Green Hill is loaded you can load the Save Sate.

sonic delta 40mb is a very impressive hack. playing thru sonic 1 to sonic and knuckles with extra levels? pretty kino. however i have a few gripes with the hack. first, some sonic 2 beta level layouts were changed in the final game for a reason (metropolis i'm looking at you). speaking of this secondly sonic 3 and k have a lack of beta inspired elements aside of the soundtrack option. third robotnik winter zone's artwork clashes with the rest of the game. despite all of this i enjoyed playing thru the game.

Hopefully AIZ was fixed from the last version, it was bugged to the point where I couldn't see anything. Thank god I've memorized the layout from the original game. (I have not yet played this version yet.)

AIZ was fixed, but Winter Hill now crashes the game.

I've been following the evolution of this hack for years and the evolutionary aspects are undeniable. From the refinement of sonic 2's beta zones (little by little each one may have a unique boss), as well as the numerous bug fixes that permeate the three games. Sync two different sound drivers, plus physics review. In technical terms, it's probably the best job, without a shadow of a doubt.

Congratulations!

A very interesting rom hack that is a fun pick up and play of sonic 1-S3K. It has a lot of customization and a very good secret zone! I would really recommend playing this!

Excuse me, how do you access the Level Select screen now that the sound test is just part of the options menu?

Neto @ 2021-10-12 21:12:02

The Sonic 3 Code (Up, Up, Down, Down, Up, Up, Up, Up) on Title Screen still works unlocking the Cheats option, but these can be input in the Options menu Sound Test

[*]- 1,9,9,1,0,6,2,3 - Level Select Menu;

[*]- 1,9,9,2,1,1,2,4 - Debug Mode;

[*]- 1,9,9,4,0,2,0,2 - All Emeralds;

[*]- 1,9,9,4,1,0,1,8 - All Super Emeralds;

[*]- 1,9,7,7,0,9,0,5 - Unlock "Play "Bridge"" option.

Hi Neto. The game crashes when I input the Super Emeralds Code. Any reason why?

The entire trilogy in one big package, along with some of the lost levels from Sonic 2? That sounds like a lot of fun!!! I still can't believe that this hack actually exists.

santiago95yk @ 2021-10-17 08:48:58

why does still the sonic 3 sprite is here,ITS TOO REPETITIVE IM TIRED OF SEEN IT!,EVERY HACK/FANGAME THAT I DOWNLOAD HAVE THAT UGLY SPRITE!!!!,ITS HARD TO SEE THE SONIC 2 BETA SPRITE HERE?????,THIS HACK IS LITERALY FOR SHOW SOME BETA STUFF OF ALL THE OG TRILOGY OF SONIC AND YOU PREVIOUSLY ADDED THE SONIC 2 BETA SPRITE IN A OLD VER. OF SONIC 2 DELTA JUST ALL OF THE COMUNITY AREN'T TIRED OF SEEING THAT ####### SPRITE????

Kronos @ 2021-10-17 18:50:36

How have I known this hack for a long time, I'll do some feedback. 1) One appropriate name for the project would be Sonic Universe, because the game includes all 16-bit zones of the mega.2) The save system helps, but what if the player wants to play only sonic1 or sonic 2?! So, customizing the entries of a new game would be interesting. 3 )Insert in the options menu the possibility for the player to choose the sonic with the graphics of sonic 2, 3 and Mania, as well as Tais and knucles.

Success.

Estou feliz com a evolução que o delta sonic vem apresentando, no entanto tenho como queixa o layout da fase beta de sonic 2 winter hill que foi modificado para o de triple trouble. Seria legal se víssemos também a jungle zone, assim como vimos a bridge zone. Ah, quase esquecia de dizer sobre o bug em sonic 1, quando pulamos para pegar os escudos escondidos nas palmeiras em green hill zone e nada acontece está sem física.

I'm happy with the evolution that sonic delta has been showing, however I complain about the sonic 2 winter hill beta phase layout, which was modified to triple trouble. It would be nice if we also saw the jungle zone, just like we saw the bridge zone. Ah, I almost forgot to say about the bug in sonic 1, when we jump to get the shields hidden in the palm trees in green hill zone and nothing happens it's no physics
