Sonic 3 & Knuckles is an action platformer game for the Sega Genesis.

This version is largely the same as the original Sonic the Hedgehog 3, but adds Knuckles the Echidna as a playable character, and features the levels from Sonic & Knuckles alongside the ones from the original game.

This is a hack for Sonic 3 & Knuckles for the Sega Genesis. Sonic 3 & Knuckles is Sonic the Hedgehog 3 locked onto Sonic & Knuckles. This hack adds challenges featuring various characters with various objectives. Some levels have been altered in ways such as removing all special stage ring entrances or moving bosses to other levels. Challenges include Time attack, ring grab, vandal, sidekick, gravitation, tag team, body guard, ring drain, double team, high voltage, time attack, and final battle. For detailed descriptions of what each challenge is about see the readme.

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