Ok thanks.As i understand, the league they still have to announce is Liga Aguila and that is already ingame.
So there's no problem to begin with.zlac has explained it already.
The database isn't the problem here, you can add as much .bin files as you want.
The problem is the EDIT.bin file which only can handle about 150 (unlicensed) teams. So as long as Konami is adding licensed leagues, it shouldn't be a problem.
