Batman in english with subtitles

[FerM93]

emm hi
I had a "problem"

I'm from Argentina, so i speak Spanish (daa xD) but i like the original voices of the game.
I try to put the game in english with spanish subtitles but i still can't do it
Can you help me to do that?? The only thing that i can do it's put the videos in english with the correct subtitles in spanish but the in game subtitles are still in english, or put the ingame subtitles in spanish (with voices in inglish) but the videos continues in Spanish (remember, i just whant subtitles in spanish, not the voices)

I was watching the game files and i understood a little bit but i still can't put the game like i want it

Any idea???

PS: Sorry for my bad english U_U
