Marc420,
I saw that you were asking about a place where you could download re-rated versions of fighters. Be VERY careful when doing this! The ratings that are already on the game have been done by Jim and Tom Trunzo... who are experts at this. Before you do anything, I would go to the articles section of the Title Bout website and read Jim Trunzo's "Explaining the Ratings" (or something like that). Every different rating effects all the other ratings... it is a very complex system. Before you go changing a bunch of stuff, I would learn everything you can about how fighters are rated.
If and when you do download re-rated fighters, I would save them in a seperate database... that way you will always have an original DB (good idea).
www.cornerwork.com is by far the best place to go for fighter downloads that have been created by users. You will also find tons of other stuff as well.
I suggest the first place you visit though is Cube's website. Here, you can get photo packs that have pics of just about every fighter in the game. If I am not mistaken, Cube also has the ENTIRE Cornerwork.com fighter database (DB) available to download... that would save you alot of time and effort. Good luck! PM me if you have a question for me.
