Proto:Sonic the Hedgehog 2 (Genesis)/0524 Build
 | This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes. Notes: A lot of things need to be added, some final screenshots to compare with the prototype, rewording, etc. |
This is a sub-page of Proto:Sonic the Hedgehog 2 (Genesis).
The 0524 Prototype build of Knuckles in Sonic 2 is the earliest known prototype that was dumped.

Differences
| 0524 | Final |
|---|---|
|
|
The KNUCKLES THE ECHIDNA IN banner above the title screen emblem isn't implemented yet, but the emblem still descends to make room for it. Graphics for the banner do exist in the ROM however, even though they go unused. The PRESS START text is positioned slightly lower then in the final.
| 0524 | Final |
|---|---|
|
|
Chaos Emerald result screens in the prototype don't mention Knuckles anywhere.
Sonic 2 Leftovers
Level Select: A + Start at Title Screen.
Debug Mode: A + Start while selecting a level from Level Select.
| 0524 | Final |
|---|---|
|
|
When Knuckles goes Super in this build, it still uses Super Sonic's palette. The final uses the palette from Sonic & Knuckles.
| 0524 | Final |
|---|---|
|
|
When the Super form wears off, Knuckles mistakenly uses Sonic's regular pallette. This is fixed in the final.
Oddities
- Knuckles acts rather erratically in the demos.
- In Casino Night Zone Act 1, using the left flipper to go to the top left corner of the map will make the game freeze.
Though, you can avoid this by holding Left while rising from the flipper.
