Sonic 3 has an unknown Zone, possibly an ending, following The Doomsday Zone ($0C). Although it cannot be accessed without crashing soon after, if you escape before it crashes, severe RAM corruption ensues.

Codes to access:
$0D Act 1 ~ ABZA-A4ER
$0D Act 2 ~ AFZA-A4ET

Fix intial crashing (both acts) ~
NKCA-LABR

Select Angel Island Act 1 or 2, depending on the act you wish to play.
