Friend on a site sent me to this thread.
I'm the guy who wrote the original software and I gotta be honest, this is awesome that someone took it and went off with it.
I believe this version did not let you add moves, although the version I have done since (not released) does let you add moves, and strings for the moves. Originally I made it as a home project, and using poser I created renders for each of the moves, so you would essentially watch the match as it happened through poser renders. Some of those things would be impossible as a sim released that let you make your own wrestlers, so I'd have to change some things.
But found this thread and I think it's awesome.
