yesterday I made another one, replaced kits (premier league only), and some balls (bluemonkey's balls.bin). This is what I did:
1. replaced every empty kit slot with a dummy kit (as told by others and thanks for this solution)
2. Replaced arsenal bins (bluemankey's files)
3.all the other kits replaced png's I found from a pc patch
4.replaced the balls bins (starting from ball_3, 4 and then 3 and 2)
5. Replaced param.dat file (bluemonkey's one)
6. remove hard disk, so no option file to load
The game loads, kits and balls replaced.
Only one thing was wrong, on the next 2 teams after arsenal I don't have a goalkeeper on the edit menu.When I try to play with one of those two teams the game freezes. I checked my files and I found that in the 2 lasts teams i mixed up the kits. I don't know if that mix up causing the goalkeeper missing on the other teams. I checked the param_dat file and it is relinked ok.
Sorry for my big post
I want to thanks, Bluemonkey, Keess, seanw and everybody in this and other forums for their hard work. Cheers mates!!!!!!
