Art

Art	Offset	Description
	000D36C0	An earlier version of Sonic's falling pose for the Sonic & Knuckles title screen. The shading for Sonic's eyes and chest is unpolished.
	0	Work-in-progress title screen frames for Sonic & Knuckles. Like the above graphic, Sonic's eyes and chest are lacking polish in the shading, while Knuckles is mostly finalised save for a few pixels on the shoes. The placeholder numbers for the animated tiles can also be seen in these frames. The fourth frame in its unfinished state can also be seen on the MTV television show, Rock the Rock.
	000D4D90	An earlier version of the Sonic & Knuckles logo for the title screen.
	00165240	An earlier version of the Sonic & Knuckles logo for the endings. Pro Action Replay code FFFFAE:0001 will force the game to display this logo in Knuckles' ending instead of the Sonic the Hedgehog 3 logo.
	0	A unique ending pose for Sonic that goes completely unused. No mappings appear to exist for this graphic, so its assembly here is based on guesswork.
