I hope OP doesn't mind, but using the Madden Roster Editor I have made a roster (using the Week 6 update in Madden 25) for Madden 10.
I have had to make a few alterations (there are no portraits--I have zeroed them all out to silhouettes due to freezing issues--too many players had portraits not included in Madden 10 or had incorrect portraits), and Madden 10 has a 54 player limit per team (and a limit to total roster size of somewhere around 2172), so I have cut the rosters down to 54 (tried to take into account players who were signed due to injury and put them back in FA so as to not cut players who are currently on IR) and had to delete some free agents (mostly long snappers and the guys EA puts in from contests or whatever, as well as the more lowly rated/old retired players).
So it's not a perfect roster, but if you play around with it some, you can adjust it to your liking.
Here is the file.
NOTE: This is from the PAL version of Madden 25 and Madden 10, but I have unlocked the file so it should work on all systems...If it doesn't, use BruteForce Savedata to decrypt and then update with your console ID/game region ID and encrypt again...should do the trick.
