Play Sally Acorn in Sonic the Hedgehog 2 Online

Sally Acorn in Sonic the Hedgehog 2 is a fan-made hack for the Sega Genesis, originally developed by Sega and released in 1992. It takes the familiar structure of Sonic 2 and replaces the blue hedgehog with Sally Acorn, a character from the Sonic comic series. This kind of modification was a niche but creative part of the 16-bit era, showing how players reshaped existing games to fit new ideas.

You control Sally Acorn through the same zones as Sonic 2, but her movement and abilities feel distinct. Her jump is slightly different, and her sprites are all new, which changes the timing on platforming sections and boss fights. The main goal remains the same: race through levels, defeat Robotnik, and collect Chaos Emeralds. The pacing is fast, and the difficulty mirrors the original, though some players might notice subtle differences in how Sally handles compared to Sonic. It feels like revisiting a classic with a slightly altered rhythm.
