Im having a lot of trouble downloading games. Not many are coming up in my search, and many times after downloading a game, it turn out to be something else!

Im looking for:
-max payne 2
-jedi knight 3: jedi academy
-mafia

anyone seen any of these floating around?

also.....

Does anyone have a working version of any of the tony hawk games...except tony hawk 1 (already have it)?
any one of these would be great
-pro skater 2
-pro skater 3
-pro skater 4
-underground
-underground 2

Pc version would be prefered, but im also looking for a nintendo 64 rom of pro skater 2 or 3.

Any help would be much appreciated.
thanks
