Unused Artwork

Character Sprites

Artwork Name Description
S2tailseggfan.png "Crying Tails" Animations Some unused sprites of Tails crying. Probably meant to be used in the ending cutscene when he is rescued.
S2sonic.png Bored Sonic Animation These three animations are actually from Sonic 1 for the Master System, but were found in Sonic 2 for the Game Gear. Sonic 2 GG used Sonic 1 MS's spriteset, but the waiting animation was changed. This is all of what is leftover.
