Ow, thanks dude. I managed to edit perfectly!
Taking advantage, I have a problem when compiling .bfs again. The original size of data.bfs is +/-2600MB, but when I extract and compile again it is about the size of +/-2300MB.
When starting the game, a message that I do not remember, but it is something invalid '0 '. I'll take a printscreen.
Thanks for your help!
EDIT:
This is a error mensage and size of ori_data.bfs (original) and data.bfs (new).
