The player starts most Acts positioned slightly more to the left than they do in the final game.One can be placed via Debug Mode, where it can be seen that they have a totally different design to the one used in the final game. Special Stage cannot be selected on the level select, as they don't exist yet.The level select has the same general appearance as the level select from Sonic 1.Rolling demo gameplay is the same as the Nick Arcade build, and has not yet been rerecorded to fit subsequent layout changes.

This is because the two prototypes have the same serial code as Sonic the Hedgehog (REV01), which determines the result of the lock-on.

Magazines from the time attributed the leak to a specific magazine, while Yuji Naka stated in 2005 that it came from a demonstration cart that was stolen from a New York toy fair in 1992. The origin of the actual ROM image is unknown. However, it is believed to have first been leaked in September 1992 and distributed through BBS (bulletin board system) numbers. The prototype is named after Simon Wai, who found it on a Chinese GeoCities page in 1998. In addition, there are a few levels not seen in the final, but most of them contain nothing.Īccording to drx, this prototype was built in early August 1992. There are also many, many unused graphics that can be found via hacking. The Simon Wai prototype of Sonic the Hedgehog 2 is definitely further along than the Nick Arcade build, but there are still quite a few unfinished elements such as level layouts and things that have not been fully implemented.
