Sonic 3 Complete

A plethora of tweaks, improvements, bugfixes and options for S3&K, with (optional) music based on the original PC version, and an integrated way to play the subcomponents of S3&K (Sonic 3, Sonic & Knuckles, Blue Sphere) through Classics.

See the Sonic 3 Complete[] website for more info!

How do I play this?
  1. Buy Sonic 3 & Knuckles on Steam.
  2. Download it. You should then have "SEGA Genesis & Mega Drive Classics" in your games list.
  3. Click Subscribe on this mod. Sonic 3 Complete should download as workshop content for the Classics app.
  4. Now play "SEGA Genesis & Mega Drive Classics".
  5. In game, select Sonic 3 & Knuckles on your shelf, press the displayed button for Mods, and then press the Play button on Sonic 3 Complete.

Known issues (Steam/SEGA Classics version)

Game doesn't save in the current version of Classics Hub.
In-game save files don't seem to work at all on the hub. You can work around this by creating a savestate at the title screen after having made progress and set your preferred menu options.

No customiser options
The features available by customising the base ROM through the website customiser or IPS patches aren't available through Steam at present, as there is no way to customise the Workshop entry. We're hoping to make this content available here eventually, one way or another.

I can't save on s3&K on its own?

Technically yes, you need to own the game (which I do)

is this legal to download off of the sonic 3 complete website without steam?

PS: also even if there are nitpicky configurations it's still good to have the possibility to change some quality of life stuff and look of your Sonic (like playing Sonic 2's sprite instead of Sonic 3's)

@StixsmasterHD because this mod is more than just having Sonic 3 standalone and Sonic & Knuckles bundled together.
First of all: it fixes a lot of minor issues (like glitches, visual differences, etc...) because they all adds up.

There's a lot of stuff from Sonic 3 that is "lost" once you play it with & Knuckles.

Also it's not unstable, I encountered no glitches. Anyway you're free not to download it but it's the definitive experience with Sonic 3 Angel Island Revisited.

I dont see why peeps would want this mod when you get Sonic 3 & Knuckles when you buy Sonic 3.

there is absolutely no reason for this mod unless you want a more unstable version of the game and the ability to make nitpick configurations.
