Sonic the Hedgehog 2 (Simon Wai Prototype)

The Simon Wai Prototype of Sonic the Hedgehog 2 is probably the most interesting build of Sonic 2 so far. The build is much more complete than the Nick Arcade Prototype, but is still far from completion, with many things still unimplemented.

It was originally found by Simon Wai on a Chinese Geocities site in 1998, it was likely stolen from a New York toy fair in 1992, then dumped. Until earlier/later builds were dumped, it was simply called "Sonic 2 Beta".

The build has many things removed from the final game are present here, along with some other interesting things.
