you can do that with any hex editor really...
Also, i was able to replace the club names at runtime with debugger, so i can write a little kitserver module to do that. (Hopefully, we'll be able to do the logos also, not just the names).
So my first game with "Chelsea" as opposed to "London FC", turned out to be quite a drammatic one. Was losing 0:2 until 78th minute, couldn't buy a goal in that game, until Essien's mishit ended up in the net. Went on to win 3:2, with Schevchenko scoring the winner in stoppage time. Life felt good
