So I'm interested in running this game, but I only own the version that was released on the PC Sega Smash Pack in 1999. Now, this version is actually believed to be an unfinished prototype of the game at some point late in development, which was erroneously added to the PC compilation instead of the final product. It has a large number of differences from the Genesis version, some of them quite major. A comprehensive list of differences can be found here: http://rq87.flyingomelette.com/RQ/SS/S1/proto.html

Some of these differences, such as the 3rd, 7th, and 8th bosses automatically ending in seconds, and no enemies present in 8-2, would probably warrant a new category in my opinion. In addition, the prototype also has an option for invulnerability, and a level select readily available in the option menus.

Once again, really interested in running this, so it'd be cool if we could discuss adding a new category for this version, and how the rules should be set for it. Let me know what you guys think! :P
