Hack of Sonic the Hedgehog 2


This is a hack of Sonic the Hedgehog 2 which allows Sonic, Tails, and Knuckles to play simultaneously in any level from Sonic 1 and 2. All characters retain their moves and abilities from Sonic 3 & Knuckles. Save game and shield abilities from Sonic 3 & Knuckles are also present. The original shield gives Sonic the ability to perform a air/dash by pressing jump while in the air. Sega Multitap compatibility is implemented allowing up to 3 people to play at once. An extensive list of features of the hack can be found in the readme.

The game was formerly known as Sonic 2 Heroes before ColinC10 became involved and helped port over Sonic 1 levels. Some features of this hack were first seen in ColinC10’s Sonic 1 and 2.

The patch is in xdelta format due to shifted data resulting in IPS patches containing original code.


Version 0.10.008a adds the ability to play as Espio, Charmy, and Vector from Knuckles Chaotix.

My Wildest Dreams Come True

Reviewed By: Eldrethor on 24 Oct 2018

Anyone who grew up with Sonic has likely wondered what it would be like to have Tails or Knuckles in Sonic 1, or have the entire crew zipping through Sonic 2. Heck, this hack proves that someone out there was really yearning for Team Chaotix to make an appearance as well. This hack delivers all of that in a single package, and while the results are admittedly game-breaking, it’s great being able to sprint through Memory Lane with such a robust cast of characters.

As the description states, this hack grants you a total of six playable characters across Sonic 1 and Sonic 2, and the amount of options that you have at your fingertips is stellar. You can either go with a full team of three or limit yourself to one or two, untethered or tethered a la Knuckles Chaotix, along with a level select. For those who have always wanted to play with Knuckles or Tails in Sonic 1, that dream can finally come true. Sonic also gets his midair spin attack, along with his later sprites, which look much more robust than the ones from his Sonic 1 incarnation.

Another nice touch is the modified ending to Sonic 1, which now features a seamless transition into the beginning of Sonic 2, along with cameo appearances by Amy. It’s done with such a clean, professional touch that one would swear that the minds behind this hack must be working for Sega.

The one thing to keep in mind when stepping foot into this hack is that unless you’re playing with just Sonic or Espio, it is obscenely unbalanced. The levels in Sonic 1 and Sonic 2 were never designed for the kind of mobility that characters like Tails and Charmy offers, and you can easily skip entire sections of the game simply by flying over them. The game also spreads power-ups across your entire team, which creates a situation where a single shield power-up can grant you a whopping three to burn through. Yet despite all of that, solo runs are generally okay, and these levels are not new for many Sonic players; the fun is in running through their old, familiar stomping grounds in ways that were not possible back in the day.

If there are any gripes to had, one is that I would argue that Espio is a bit out of his element in this hack, and this is because Sonic 1 and 2 were never designed for his ability to run along walls and ceilings, which leaves his character feeling tragically bland in comparison to everyone else. This is more so the result of poor circumstance though, and not the ones behind the hack.

The other issue is that the Choatix-style tether, which was a core feature in the Knuckles Chaotix levels, is a bit of an odd duck in Sonic 1 and 2. Here, it seems to exist as a way to keep three human players working cooperatively, but is otherwise insignificant for a one-player experience.

Overall, this is a very clean and fantastic hack with a lot of love and care put into it. Sure, having three shields or Charmy just zip through entire stages is incredibly game-breaking, but what you get are new and exciting ways to explore old and familiar grounds, and it’s an absolute blast.
