Scratch what I said before:
The teams are like this:
team00A.wcf
team00A.wcl
team00A.wcs
team00A.wct
team00B.wcf
etc. etc.
Any clues? I also haven't found the AI yet...hold on.
Also, what are .CAA files? They have loads of files stored with names like:
C_BatShortrun_01.CAA
C_BatShortrun_02.CAA
C_BatShortrun_03.CAA
C_BatShortrun_05.CAA
C_BatShortrun_06.CAA
C_BatShortrun_09.CAA
C_Bowlpoorlength_09.CAA
C_Newbatsman_03.CAA
C_Newbatsman_05.CAA
etc, etc, in a file called play-by-play. This could be the commentatory, except that there is another file called commentatory, although the files are also in .CAA format...
