Sonic 3C Delta

By Chainspike

Sonic 3C Delta is a hack of Sonic The Hedgehog 3 (& Knuckles). It is a compilation of early/unused content for Sonic The Hedgehog 3, including early music, layouts, graphics, concepts, and more.

The hack currently includes all the zones from the first half of Sonic 3, including Flying Battery Zone in its original placement and the 3 Bonus Stages.

General Changes:

  • Original zone order.
  • Improved prototype soundtrack.
  • Prototype inspired level layouts.
  • New title screen and menu art.
  • New cutscenes.
  • Prototype graphics and art.

This hack was a huge undertaking, so I hope that you all enjoy playing it as much as we did creating it!

Probably my favorite hack. Nice to see the proto hyper stars

Herobrine100x @ 2021-10-11 14:50:43

How do you call tails (Saw in RHS' Vid), and what's the code for level select, other than that, great hack.

Chainspike @ 2021-10-11 21:06:06

Up + A, and thank you.

Herobrine100x @ 2021-10-16 15:40:09

Thx, still want to know what the level select code is.

Chainspike, could you please remove the "Rodotnik" name from the credits? I really don't want the name to exist

Unforunately, I cannot edit the entry page, but I'll keep that in mind for the credits screen in future releases.

On carnival zone act 2 just after knuckles shut down the lights there's a dead end just jumping down over the two red barrels, it's like a camera bug, and another bug it's sonic no fitting inside of the fire shield.. thanks for the hack ^^

Chainspike @ 2021-10-11 21:05:38

You can use the Game Genie code RCNT-GJRA to fix this bug. This was unforunately a bug that was missed for the demo. Sorry about that. I'm happy to hear that you like the hack though.

i get in this after catching a bonus(i get pissed)

KnightTrrr @ 2021-10-12 09:15:41

Where's the breakable block, at the beginning of ice cap 1, from?

RetroForever15 @ 2021-10-12 14:58:42

A top tier hack. It's quite fun, and it feels very authentic. Can't wait to see what comes next!

donus87 @ 2021-10-13 10:50:43

hi guys, i just signed up. i saw the sonic 3C delta demo on YT and tested. and in itself it is a cannon shot of beauty, but unfortunately something happens to me, and that I have to play with it on my psp or kega fusion. but in mega drive + mega ever drive pro it does not work well, indeed it distorts me when I do some kind of action even just sonic brake. so i ask ChainSpike if it is normal for it to do this since it is a demo or is it my MD having problems? Thank you.

Chainspike @ 2021-10-13 21:46:21

This is not normal, and it appears to be a problem specific to the Mega Everdrive Pro. We're currently looking into this.

sixteenbitify @ 2021-10-15 01:12:43

I am using a Mega Everdrive Pro with a Mega Drive II and I have not experienced any issues that donus87 is facing. Infact, it runs almost perfectly on real hardware in my case. The only real issue I encountered was the CNZ Act 2 bug, which was fixed by that Game Genie code.

a friend of mine who knows more than me said in contextual words: Many sonic hacks are designed on emulator and therefore go bad or don't start right on real hardwere; and I thought it was a problem with the MD and its capacitors or whatever. and instead crashes. in flying battery after the end of act 1 the BG changes positionso. if you can correct it please. thank so much.

Sonic 3C Delta runs without issues on real hardware, which is my unmodded JP Mega Drive 1 and EU Mega Drive II with the Triple Bypass and Region mod. Sorry to hear that you're having issues with your hardware.

donus87 @ 2021-10-15 04:48:07

in fact my MD 1ASIA has the change of the region and it was quite stopped but then after 4 years I put it back to work.then it's my MD who might have the problem. "a little" the rom works, but how do I do the spin dash or instant screen, it distorts everything and I don't see anything. dammit!

donus87 @ 2021-10-15 13:15:32

Yes. my problem is in the hardwere of my MD, I talked about it with 2 of my friends. he doesn't read it right, I'll have to try it with another MD. it is not a mistake of the rom I'm sorry Chainspike. however it is done really well.

Nightborger @ 2021-10-15 07:43:35

This hack took the Number one place on my top 3 from Sonic 3 AIR. I will get some real hardware and an everydrive soon. But I have a question about that, Wich Everdrives support this game?

Thanks in advance!

donus87 @ 2021-10-18 08:48:23

dear chainspike, i noticed some bugs with psp, in this sonic 3 made by you:

1) FBZ act 1 After the miniboss, the BG moves to the right abnormally

2) FBZ act 2 in a master ring room the collision makes me fall into a dead center

3) the damage to the mini bosses is 8 and not 4 as in CNZ or 6 in the other zones

4) damage to Eggman, example: in AIZ when he destroys the bridge you give him a few shots. but he doesn't record them,only after, so even in MGZ

5) sonic and miles when they come down from the vines make them do the rotation.

6) when you enter the "S" box in HCZ (thanks to debug mode) the bgm starts with the Hyper form, and ok, but, after you meet Knux and destroy the bridge, it starts with the Super / invinc. bgm

7) in FBZ 2 the second spiral net, where there is the transporter spider, misses the collision. I go through it with any charas.

they seem like subtleties, but they are. I understand that he must mirror the proto, but let's not exaggerate. I'm sorry if I write a lot, but in this way you will always do it better and to perfection. :-) I will not see the hour of the second part or complete version of the rom :-D

this hack is cool, for next demo you can fix that trap(when i played for first time after a bonus, i get pissed in trap). you can also tweak super sonic sprites(look up,hang,spring,etc.)
