You have to open the gamedata.bag first, inside the Brian Lara folder. Once open, you can use the import feature to import the correct file. You may also have to set it to all files, as the file has bracket as the end with (bats) in it, this means it is not actually any file type.
However I have a question of my own. I wasn't paying attention when I imported the gametext.bag and rather foolishly have imported over the wrong file. I believe it possibly be one of the fonts files, or maybe menu text?
Anyway, my game now has no writing in any of the menu bars. So for example, just a box with no loading in it, a menu with no Exhibition or Options etc.
I was wondering if anyone possibly had the file that I am missing so I reimport back into the game.
If you need a screenshot, or my gamedata.bag to find out exactly what file I will be only to happy to send it to you.
Thank you to anyone who can help.
