Nick Arcade was a US game show that aired on the Nickelodeon television network in the United States from 1992 to 1993 airing originally during weekend afternoons.
Sonic the Hedgehog 2
Sonic the Hedgehog 2's appearance on Nick Arcade was unusual in that it was actually a prototype version with different background music and level structure. A copy of the prototype was found and dumped by drx in 2006.
A notable contestant who played Sonic the Hedgehog 2 on Nick Arcade was Melissa Joan Hart, who appeared on a special Clarissa Explains It All celebrity episode. She later went on to star in a number of other TV shows, including ABC's "Sabrina the Teenage Witch".
Sonic The Hedgehog
A pilot episode of Nick Arcade was recorded in early 1991. This was before the official release of Sonic the Hedgehog for the Sega Mega Drive, but the producers managed to obtain a prototype version of the game for use in the pilot. One notable difference in the featured prototype is a rolling version of Eggman's ball (from the Green Hill Zone boss). The ball seems to not kill Sonic but instead push him. Sonic can also stand on top of the ball and jump on it. The ball seems to be using 2/3 frames unlike the final version of the game.
