So if you have been keeping up, I have been releasing some of the sounds from the demos and also ported the tutorials/special features from consoles for PC. If you're interested, you should check them out. This is the magical tool that does the legwork, receiving its first public release:
https://github.com/phantom567459/SoundFMVextractor/releases
I won't go into the details (there's a readme and source code for that), but essentially, you can take any file from the BF1 sound folder (common.bnk or .lvl files), follow the instructions on running it, and receive mostly playable sounds from it. I say mostly because you need a program to listen to the compressed sounds from the .lvl files, but they can be converted and munged back in without much loss at all (there's not really a recompression phenomenon).
Right now, it only does BF1 sounds, but next on the "Features" list is BF2 support. Common.bnk for BF2 already works (same exact format) but you should make sure you use the BF2 switch for compatibility reasons anyway.
If you want the program, up above links to the release quality exe. If you're so inclined, hopefully I commented the source code well enough for those who want to look at it to understand it.
I would also like to ask anyone that has the language localizations to please contact me - For a bigger project I am hunting down the alternate languages.
I have issued an update to this program: https://github.com/phantom567459/SoundFMVextractor/releases/tag/1.1
New Features:
BF2 support
PS2 TCW support
I'll give it a whirl when I get the chance! This will come in handy for a mod I haven't actually announced on here.
Heh, didn't realize this was what you were talking about when I replied on Discord. I'll definitely make use of this. I want to add the preview flyby videos to SWBF2 Xbox at some point.
