Prerelease Info

Unused Graphics#

Early Graphics#

To do: Early versions of sprites for Knuckles are used instead of the final ones.

A larger HUD that was seen in pre-release material.

Graphics for the Sonic & Knuckles banner and Mushroom Hill intro graphic, looking very much like their Genesis counterparts. The final game doesn't bother with Zone names and instead just uses Act numbers.

"No Lock On"#

Presumably, Sonic & Knuckles would have had support for "locking-on" the Sonic 2 and Sonic 3 cartridges for new content, similar to the Saturn version. This would be the icon shown when playing Sonic & Knuckles by itself.

In Sonic & Knuckles Act 4, a set of rings are misplaced. They were intended to be in the loop, but are shifted slightly to the right and up of their intended positions.
