This article is outdated.
Due to changing events, this article is either no longer correct or needs information added to it to make it complete. Please update it so that it meets current knowledge.

It has been proposed that Sonic Mega Collection/Hidden content be renamed and moved to a new page.
Reason for proposal: Page is now set up to be moved to "Sonic Mega Collection/Hidden content".

Select Sonic 1 revision

By default, Sonic Mega Collection will load REV01 of Sonic the Hedgehog, but two other revisions can be accessed by entering button codes when displaying the Sonic 1 info screen:

To play REV00 (described as "US"), press .
To play REV01 with the "spike bug" fix (described as "JP2"), press .

In PAL versions of Sonic Mega Collection, 60Hz mode must be enabled in order to input the above codes (hold on startup).

Unused content

Sonic CD remnants

When hacking into Sonic Mega Collection, one can find the entire European Sonic the Hedgehog CD manual. Not only that, but a preview version has Sonic CD on the list of games to pick. On the same preview version, in the movies section, you can find "Sonic the Hedgehog Movie Part 1" and "Sonic the Hedgehog Movie Part 2", likely meaning that the Sonic OVA was once in Sonic Mega Collection.

A Sonic Mega Collection prototype released by drx actually has all of this stuff included, however the movies and the Sonic CD game are nonfunctional.

Sample videos

Three videos exist within the game's data and are all copyrighted to CRI Middleware Co. Ltd., which helped Sega with AV-related things for their GameCube titles. While it is likely Sega was testing the Sofdec player and simply didn't take these files out, the movies and songs take up roughly 20% of the data...and even then, there is still empty space on the disc. This space could have easily been used for more games...or even Sonic CD, which allegedly couldn't be included partly because of "space limitations".

sample.sfd

sample.sfd is a test video for CRI's Sofdec video compression technique for developers. If opened by FFPlay or a similar player that can play Sofdec/ADX files, the unused song is played as well (see Music below).

loopbgv.sfd

loopbgv.sfd is nothing more than a CG water rippling effect somewhat like the Sonic Team logo animation from Sonic Adventure. It lacks any sort of sound and only lasts 12 seconds. The purpose of this clip, aside from showing off Sofdec's capabilities, is currently unknown;

smpinter.sfd

smpinter.sfd is a 30-second clip of San Francisco. This might be from CRI, since they do have offices in San Francisco, It is suspected to be a test clip from the Dreamcast development kit.

Music

music24a, a three-and-a-half minute track used for a video intended to demonstrate the capabilities of the Sofdec codec (see above).
The music for the 2P Battle menu from Sonic Adventure 2: Battle also exists in the data, likely meant to test the ADX music format.
