* Level select can be activated at the title screen by pressing {{Icon|arrow-circle-up}} {{Icon|arrow-circle-down}} {{Icon|arrow-circle-down}} {{Icon|arrow-circle-left}} {{Icon|arrow-circle-right}} '''B'''
* Minor code changes in all files.
* Wacky Workbench Act 2 (Past and Good Future) and Stardust Speedway Act 2 (Present and Good Future) contain the most differences in this build (R62B, R62C, R72A, R72C).

=== Palmtree Panic Zone Act 2 (R12A/B/C/D__.MMD) ===

A critter that jumps around in good future is removed in the final:

054E 028E A401 E000

A spring and a rock that stop you were added in the final. The goal post is also moved to the right in the final.

26C8 02D2 9600 E000 (goal post)

is replaced by

2628 42D8 0A0A 2000 (spring - past)
2630 42D0 0A0A C000 (spring - present, future)
2730 02C4 9600 C000 (goal post - present, future)
2738 02CB 9600 2000 (goal post - past)

=== Metallic Madness Zone Act 2 (R82B__.MMD, R82C__.MMD) ===

The prototype has two places where Mini Sonic can fall through the wall in Metallic Madness Act 2. The final adds the following two objects which act as barriers to fix this bug:

0910 0710 0900 2000
1A20 0110 0900 E000

<gallery mode=nolines heights=168 widths=240>

Sonic CD 810 - MMZ2 Good Future Mini Sonic Collision.gif | Good Future (1A20 0110)
</gallery>

The block causing the first bug was also reinforced with collision on the top and bottom so that even if you fall into it, you won't fall through the bottom any more. The column causing the second bug was also reinforced making it entirely solid. In the prototype, it has collision holes in the top corners and it's hollow inside.

=== Quartz Quadrant Zone Act 3 (R53C__.MMD, R53D__.MMD) ===

The boss in both good and bad future has a different color

=== Visual mode (VM____.MMD) ===

In builds 712 and 801, there are 5 patterns that are loaded into the same place in Video RAM in succession (overwriting each other). The last pattern (#5) is changed between 712 and 801, fixing the OPENNING typo. Patterns #1-#4, which presumably show the development progression of the Visual Mode are removed in the final, leaving only pattern #5.

A late prototype of Sonic the Hedgehog 2 for the Sega Mega Drive.
==Notes==
{{Tcrf link| Proto:Sonic_the_Hedgehog_2_(Genesis)/CENSOR_Prototype}}
* This prototype was originally released by [[CENSOR]] on November 9th, 1992 just a few weeks before the final game was released.
* The original ROM was modified to include a scene intro and to bypass the copy protection. The header was also modified in an effort make the title easier to see when selecting the game from a copier. "Sonic the Hedgehog 2 (CENSOR prototype).md" is a modification that removes the intro and restores the ROM back to the way it was meant to be.
* The original scene ROM uses the serial number from Wani Wani World.
* The ROM predates [[Sonic the Hedgehog 2 (Sep 18, 1992 prototype - Beta 4)|”Beta 4”]] and could potentially be "Beta 3", which wasn't included in the Sega QA Archive.
* Level select is A+START.
===Differences between the CENSOR beta and Beta 4===
* The special stages take a long time to load. This is because some of the art assets that are compressed in Nemesis format are compressed individually in this build, whereas in Beta 4 and on most of the art was compressed in one Nemesis archive instead.
* Chemical Plant Zone's loops are slanted like in the [[Sonic the Hedgehog 2 (Simon Wai prototype)|”Simon Wai”]] and [[Sonic the Hedgehog 2 (Nick Arcade prototype)|”Nick Arcade”]] prototypes. Because of this, the 128x128 Kosinski archive that contains the mapping for Chemical Plant is different.
<center>[[File:Sonic the Hedgehog 2 (CENSOR prototype).2019-02-13 08.36.18.png]]</center>
* Sky Chase has a few more rings present that were deleted in Beta 4.
* The Kosinski archive for the 128x128 Wing Fortress mappings has been modified.
* A launch pad was removed from the CENSOR prototype.
{{Compare

|}}
* A Clucker was added in Beta 4. It was probably added as a shortcut to the top level.
{{Compare

* A sign post was added on the top of the ship in Beta 4.

* The second half of the loop was removed in Beta 4.

* A sign post was added in Beta 4.
{{Compare

|File:s2censorcompare5-2.png|Beta 4
|}}
* Spawning this monitor crashes the game every time. Beta 4 fixes this by changing the object's entry in the object list from 26 40 to 26 04.
<center>[[File:S2censorcompare6.png]]</center>
* In the CENSOR prototype, it's impossible to move on to the last section of the level due to the lack of additional platforms thus making the level unbeatable. Some additional rotating platforms were added in Beta 4 before being changed to something else in later builds.

* The button that opens up the floor so you can drop down from the ceiling to fight Eggman was moved slightly in Beta 4. A propeller was removed in Beta 4 as well.
{{Compare
