I had to fix the stadiums cvs as some of the stadiums were only for a modded PC version of Madden I went through added all the new Sal CVS files and Stadium CVS, I also took out the stats cvs files for the seasons and stuff which so that players don't have weird stats that don't belong to them.
I can go into more detail but I think thats a convo for direct messages or Discord.
The file is for you and your Gamecube. You can also copy most of this over for Madden 06 you just have to remove a few ratings from the players CVS file to match that of Madden 06 players cvs file.
