1. Yes as I didn't realize 2005 would be way better than 2004 and when I did it is so expensive. 200 bucks for an EA game. 2. I know they will work but the some that I saw would replace the team's stadium and not the classic stadium. Would a simple renaming of the file fix that,. 3. I just have the MVP 15 installed. 4. I know there is a support forum but I was thinking the jerseys and stadiums were missing.
