I'm attempting to mod an mma fighters file, and career file. I've had success in finding the stats for the fighters file for a created fighter, and editing them. But when I go back to load it onto my HDD in game, the file doesnt load correctly. My created fighter is gone. Also, I used horizon to rehash/resign after edits were completed. I think I'm in need of an EA checksum fixer for it. I'm not entirely sure. Please Help. Will return favor in any way possible.
