there are 5 files needed for commentary which need to go into the correct sub folders in the game folder & the locale.ini needs to be edited to use the added commentary.
C
Program Files\EA Sports\FIFA 11\Game\
audiodata\speechdata\spa_mx
above is the path & the sub folders you need to create are in blue one inside the other in order from left to right.
these files need to be in the spa_mx folder.
commentary_graffitiruntime
commentary_repetitionpools
commentary_sentences
spa_mx.sbr
spa_mx.sbs
here is a sample of my locale.ini that your needs to look like w/ exception of the first 5 lang & comm codes that came included in my vanilla fifa version.
in blue is what i added both commentary & db files.
