Does anyone know of this mugen fighting jam?

There was this mugen fighting jam game that my uncle found online with the stages and characters already on it. I decided to start playibg mugen again not too long ago so I put together my own mugen but I really miss the old one I used to play.

I found a video of the one I used to play once on youtube but I disregarded it since I already had mine in the works... But now I really want it so I can put it on discs for my friends.

In the comments of the video, this one guy mentioned that the roster and stages the video had was of a mugen that was really popular and that nearly everyone had it. Does anyone have any idea of what that specific mugen fighting jam roster is called and where I can find it? The guy mentioned it was someone populars roster that many have.

I believe it has 600 characters im not too sure tho. I know its not 1000 or anything like that
