The Sonic 2 "Simon Wai" Prototype

The Sonic the Hedgehog 2 "Simon Wai" prototype is a widely distributed prototype of Sonic the Hedgehog 2 for the Sega Mega Drive/Genesis, which features an array of incomplete zones. It was found by Simon Wai on a Chinese website.

In the prototype copy, only four levels can be played in "normal" gameplay (though technically this is a prerelease to test some features and so there is no real level order). The rest have to be accessed through the level select code. Many are not playable, so the debug code is used to explore the acts. Genocide City Zone and Death Egg Zone are blank, causing Sonic and Tails to fall to their deaths as soon as the Act begins.

The Simon Wai prototype was widely distributed and may have been altered slightly by pirates to hide the SEGA logo from showing when the ROM boots up. The game was put on pirate cartridges with the help of a Super Magic Drive in Asia and Brazil and was then passed on as the final version. The prototype is frequently examined by hackers to determine how Sonic the Hedgehog 2 for the Mega Drive was developed.
