Sonic the Hedgehog Classic Heroes

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.

One of the greatest hacks ever made

Reviewed By: Mitsukara on 17 Jun 2016

This hack blows my mind. It blew my mind even before the Chaotix update.

Knuckles in Sonic the Hedgehog was an old dream from the days when Sonic and Knuckles was first released, that was realized about a decade ago. But this is much more than that.

You can adjust the number of characters you have (3, 2, or 1), and which order the characters are in (so you can, say, play just Knuckles and Tails, or just Sonic and Knuckles, or just Tails, etc).

You can switch which character you’re controlling easily on the fly- that ALONE sells me on it.

The game is effectively “Tails in Sonic 1″, “Knuckles in Sonic 1″, “Espio in Sonic 1″, “Vector in Sonic 1″, and “Charmy in Sonic 1″ COMBINED.

And there’s elemental shields too! And that “jump attack” shield from Sonic 3D Blast, which sort of resembles the alter games’ Homing Attack.

Tails works like Sonic 3, so he can fly. Even just Tails flying in Sonic 2 has been worthy of it’s own standalone hack in the past!

And that’s to say nothing of getting the Chaotix involved, which adds even more wacky possibilities. In fact, this is the only way to play Espio in Sonic 1 and 2 that I know of.

Even playing as Sonic is enhanced, with the lightspeed dash from Sonic CD added (and spindashing in Sonic 1 of course… something that could’ve been the entire function of a romhack on it’s own, and was supposed to be a selling point for the dubious GBA port, but here it’s just another in an overwhelming list of features). (However, my one regret here is I do wish this hack had a variant that let you use Sonic 2 sprites for Sonic, a la Sonic 3 Complete.)

You can play just Sonic 1, or just Sonic 2, or just Bonus Stages, or start wherever you want. And there’s a save feature, too- why not! Amy Rose even appears as an NPC to fly the Tornado (Tails’ airplane).

I can’t quiiiiite call this “the only Sonic 1 and 2 hack you’ll ever need” when there’s other wonderful hacks like Amy in Sonic 1 and Sally Acorn in Sonic 2, but this is still an amazing, feature-rich hack that is absolutely worth getting, and is one of the best hacks of any game I’ve ever seen.

If you’re only going to try a few romhacks (or this is your first one ever), this should be on your short list!
