The PS2 conference realignment mod is now completed and seems to work pretty smoothly, even on my SCHP-75001 slim console and PSP Go as well as emulators I've tried! Hooray! The file is available in the Downloads section under PSP or PS2. Please read the README file for information on installing it.
There is also two already created save files that start you as the University of Washington Huskies. You can read the instructions on how to modify the team you want to start with.
This mod should be able to be used on already existing dynasties as long as you do it in the offseason AND BACKUP YOUR SAVES!
