Sonic Origins Ultrafix is a large-scale unofficial patch for Sonic Origins aiming to greatly improve the quality of the collection, featuring quality-of-life enhancements, remastered audio, tweaks for accuracy and consistency, touched up graphics, bonus features, and of course, loads and loads of bug fixes! Relive all four of these classic games with a degree of polish never seen before!

Bug Fixes Galore

Over 300 bug fixes have been made to ensure the smoothest experience possible, fixing bugs introduced in Sonic Origins, bugs left over from the original remasters, and even bugs persisting from all the way back on the Genesis. No stone is left unturned!

A Truer Classic Mode

Classic Mode has been overhauled into a far more faithful Genesis experience. Super knowledgable fans will notice many small quirks from the Genesis versions restored for that authenticly crusty 16-bit experience. Spike bug, speed caps, roll jump lock... If the original had it, it's here, and a whole lot more!

Brand New Remixes for S3K

Sonic Origins Ultrafix delivers what was promised for the official collection. Sonic 3's replacement tracks have been given a true FM makeover, reimagining the prototype compositions with inspiration from the cut songs they replace! That's eight newly-remixed tracks, including a new rendition of the unused song as the new Super theme, as well as a completely new song for New Blue Sphere! Of course, the new songs can be toggled off if you prefer, and you can use other music mods, too, so you can choose the music experience that's best for you!

Fully Remastered Audio

Every sound effect has been newly re-ripped from the Genesis with the highest degree of accuracy possible. Every game's soundtrack is now HD, and can be toggled between original rips and remastered versions (Except Sonic 3, for the moment. We will include the remastered Sonic 3 music at a later date). Even Sonic and Amy's missing voices in Sonic CD have been restored and reimplemented! Sonic Origins has never sounded so crisp...

New and Enhanced Player Sprites

Full sprite sets for Super Sonic! Expanded sprite sets for chibi characters! And even on the original sprites, many inconsistencies and mistakes have been cleaned up and fixed, with special care taken not to compromise their original look and style. Any pet peeves you had with the original games' sprites have probably been fixed here!

Mission Overhaul

Say goodbye to those ugly gray mission blocks! Every stage now has its own unique block design that matches the stage's theme. Additionally, Mission Mode in general has been massively polished, with every mission being touched up beyond just the new sprites. Some have even been completely reworked! Give them a try for a new twist on your favorite stages!

Improved Game Consistency

You may know that Sonic Origins is composed of four remasters built in the same engine but developed years apart, resulting in many small inconsistencies between them. But now, all four have been brought up to a consistent modern standard, making the collection feel much more cohesive! Sometimes, it's the little things.

New Secrets

The sound tests are the gateway to many strange ways to be. Try entering some notable dates, you never know what might happen...

And Much, Much More!
