Sonic 2 Early Prototype Green Hill Zone Fix

Hack of Sonic the Hedgehog 2

Description:

This fixes Green Hill Zone’s collision errors in the recently discovered early prototype of Sonic the Hedgehog 2. You must select Green Hill Zone from the level select menu (code below). This hack also enables Tails in Emerald Hill Zone.

Level Select Code: Up, Down, Down, Down, Down, Up, A+Start

Minor problems with this patch:

  • Act 2 doesn’t load the proper end-of-level art
  • The graphics for Robotnik in Act 3 aren’t loaded
  • All level changes caused by porting to Sonic 2’s engine still exist

Patch this to a copy of Sonic The Hedgehog 2 (Early prototype) (dumped by hidden-palace.org).bin.
