Rinaldo:
Just thought I'd let you know that I've added players manually using the original ID files from WC06 (so that the commentators will call their names) and I've been able to create Jamaica and Costa Rica, and play a career as well. There must have been some error in the data I added previously, so cheers for a great program.
One suggestion, though - you could add the ability to use the team ID of your choice, provided that there isn't a team with that ID already. This would allow users to create Holland and other teams with the original ID number and get the good stuff like anthems and the kits and flags etc. that was included in the game. There are a lot of unused files in the big files, such as a face for David Seaman(ID #1) and Paolo Wanchope of Costa Rica which came in very handy for my newly-created Costa Rican team. This would also make the ability to use the original ID #'s when creating players as well, useful. Did you know that most of the players in the Japanese National team have their original faces in the big files? I found that out when I added the players using the original ID's from WC06 and creating Japan.
Wow - longer post than I had intended...
