rebuilding .OBB files?
I'm trying to change the Language on Half Life 2 for the Nvidia Shield.
So I put the VO folder from the PC version with all the .wav files into the .OBB file of the Android Version with Winrar.
It doesn't seem to work though, when I try to run it, the game attempts to redownload the .obb file ..
Is there anything I have to regard, like a signature of the .obb file or something?
Or do I need any special tools to build those files?
