Alrighty last question (with any luck). I found the announcer files (And also the entire storyline). Once I alter the sounds I want, how would I get that back into a .pck? wwise like for the .bnk?
I used a program called extr25. Its chinese or something, probably a virus. They just popped out as WAVs, but I know that the software didn't convert whatever came out to WAV, since the same WAVs also popped out when I used the Life is Strange program and the .bms script. Here is the .pck. It's quite large. https://mega.nz/#!1R5zDThR!tJbCJX0BmlzCYfDReoQ43Bv2eBq4ukmBqKkxejmqwpo
Ok, the format is usual. The only problem that in addition to sounds this PCK also contains BNK. But it seems its normal for latest wwise.
So at least I can say, it will be possible to put it all back. But you need a program to do it, and I don't know if it exists. If not, you need to find someone who will write it.
