I released a 2015-16 season update for Madden 08 on Playstation 2 now. It also includes an updated Roster and an updated Franchise save. The franchise save includes everything the PSP versions have such as updated rosters, adjusted salaries, updated coaching staffs, playbooks, draft trades, real 2015 schedules, relocation of St Louis to Los Angeles, and more!
Action Replay MAX files are available in the download section. If you need to use it in a different format, I recommend using PS2 Save Builder to convert the roster or extract the save file out!
