Sonic 3 And Sally Acorn

Sonic 3 and Sally Acorn is a 2015 Sega Genesis ROM hack of Sonic 3 & Knuckles created by E-122-Psi, with programming contributions from Selbi, MarkeyJester, and Snkenjoi. It replaces Sonic with Princess Sally Acorn, a character from the Sonic the Hedgehog animated series and Archie comics.

Rather than simply replacing Sonic's sprite, the hack gives Sally her own movement and combat abilities. She uses her handheld computer NICOLE to attack enemies, scan certain objects, and interact with the environment.

Gameplay and Sally's Abilities

Sally travels through stages based on Sonic 3 & Knuckles, collecting Rings, avoiding hazards, and defeating Dr. Robotnik's robots. She moves more slowly than Sonic and cannot rely on traditional spinning attacks.

Her custom abilities provide a different approach to the familiar levels:

• NICOLE Laser: Press A to fire a projectile at nearby enemies and certain obstacles.
• NICOLE Scan: Press B to send a scanning wave that can reprogram compatible monitors and interact with some traps.
• Downward Laser or Scan: While airborne, hold Down and press A or B to target objects below Sally and gain a small upward boost.
• Slide: Press Down while running to slide along the ground and pass beneath certain obstacles.
• Somersault Dash: Press C while sliding to launch forward with additional speed.
• Upward Dash: Hold Down and C while stationary to charge a forward dash, then release Down to accelerate.

The laser and scan functions have different purposes. Some obstacles respond to NICOLE's laser, while certain monitors and devices can be affected by scanning. Sliding and dashing help Sally navigate sections where Sonic would normally use rolling attacks.

Stages and Competition Mode

The hack uses the Sonic 3 & Knuckles engine and retains recognizable stage layouts, enemies, and environmental hazards. Sally's lower speed and different attacks change how players approach familiar obstacles and boss encounters.

Unlike Sonic, Sally cannot simply roll through every enemy or obstacle. Players must use NICOLE's abilities, carefully timed jumps, and ground-based movement techniques to progress.

Sally also replaces Sonic in Competition Mode, retaining her custom abilities. The original competition stages include Chrome Gadget, Desert Palace, and Endless Mine.

Development History and Known Issues

Sonic 3 and Sally Acorn was developed by E-122-Psi and appeared in Sonic Hacking Contest 2015. Additional programming contributions were credited to Selbi, MarkeyJester, and Snkenjoi.

The developer described the Sonic 3 version as an early build with limitations affecting NICOLE's laser interactions. Certain objects may not respond correctly, and players may need to rely on jumping or sliding to overcome some obstacles.

Because this is an unfinished fan project, gameplay issues may occur. The hack is best experienced as an experimental Sonic 3 character modification featuring Sally's unique movement and NICOLE abilities rather than a fully polished replacement for the original game.
