Self-Playing 'Sonic 2 Auto Demo' Game Gear Cartridge Surfaces

Sonic-2-GG-AutoDemo-ROMIn the video game world, we take a lot for granted. Think about all those stunning store displays, promotional posters and everything else which is used in the run up to a game’s release. While gamers today are more sentimental about these (with many appearing in collections), a lot of the older items have long since been discarded. Having said that, a rather curious auto-playing store demonstration cartridge of Sonic 2 for the Game Gear has since surfaced online.

This unique presentation would have originally been used in video game shops that were equipped with a Game Gear on display. Instead of allowing customers to sample the game themselves, Sega’s self-playing version of Sonic 2 instead showcases several of the new features and levels that were yet to be seen at the time. After this short teaser of what was to come, the cartridge displays a coming soon message with Sonic stood beside the Sega logo.

While there is no gameplay to be had in this curiosity, it’s fantastic to see how game consoles and handhelds we know and love were being used back in the day as promotional display. Having said that, several ROM hackers elsewhere on the Internet have been dissecting this release and restoring the playable aspect to it.

For those interested, a ROM of this autodemo can now be downloaded and run through an emulator or Game Gear flash cartridge such as the Everdrive GG. For everyone else, here’s the demo in its entirety on YouTube.

Strange they didn't have a more compelling demo... for producing an entire cartridge there isn't much jumping, ring collecting.. you know.. GAMEPLAY. Cool find, would like to see the cart.
