In the mean time, I recommend you check the following places: VPW2 Freem, AKI Outsiders or MPire Mall Discord servers. If you really don't like Discord, there is the r/N64WrestlingGames subreddit, but there's no active development of mods/hacks there. Sean O'Connor's Youtube Channel is also recommended.
This is amazing. I'm anxious to see how people mod arenas. I still can't figure out how to do that. I used to mod them exclusively with code, line by line, but that takes ages and sucks to the extreme.

I don't think it is (though, I know very little about hacking) but it was cool, and I'm surprised that there were never any WCW games that featured either the WW3 match or the War Games match. Or the "Tower of Doom" match that I remember watching as a kid
