Unused code for a “transition cutscene” from Sonic 1 to Sonic CD when playing as Knuckles in the Genesis Sonic compilation for the PC that ultimately was abandoned for “unknown reasons.”

It seems to be broken, Knuckles is rendered as clearing an act of SBZ, but the “act over” code gets overwritten by code for the transition and sometimes causes in crashes. Maybe its trying to load sprites that dont exist.
