There´s a trick to transfer good 1.2 OFs to 1.3!
My OF has 43 additional teams and I managed just to loose 5 players of all my complete rosters updating to 1.3
To transfer a 1.2 option file to 1.3 and keep 99,9% of all your edited content. Follow this steps:
Copy all data and your prefered edit-data to yor PS3!
Erase the Konami 1.2 Game data from your PS3
Start the Game and Download Konami Update 1.3
Ignore the wrong version message
Rosterupdate via Ingamedownload
Do not overwrite old OF, press No and confirm!
Do the Installation in system settings ingame (next to download)
Go to the editor load the OF(edit-data) and save it again!
That´s the trick! Big THX to Sark!
there are some minor flaws with the national teams of USA / Canada and Iran and you´ll loose 8 unlockable players (5 BuLi Players and 3 Classic Team Members), but you keep all your edited stuff all your rosters, all formations, all numbers, as I said 99,9%. But you won´t get any new players, I´ve done 85% of them already, so what the fxxk!
So everyone with an good 1.2 OF with a lot of self-done teams and players better use this way to make the file compatible with 1.3. The normal way of updating to 1.3 will be a mess for all new teams!
