@EKey
I'm trying to help someone extract some of the audio files from the WEM, I used your original tool and while some of the bytes look right seems like some may not be? for example i see the start of the data section but not the trailing data tag, the vorbis packets also have conversion errors so only getting first 5s of audio. Does the updated tool fix that before I download the entire game? It wouldn't let me select the folder of just audio files I have.

Ok, fixed problem with WEM files. For convert to playable Ogg format you need two additional tools > ww2ogg and revorb:

How to

Decrypt

Code: Select all

LAUTool -d 395891.wem 395891.wem.dec


Convert decrypted Wem file to raw Ogg

Code: Select all

ww2ogg --pcb packed_codebooks_aoTuV_603.bin 395891.wem.dec


Fix raw Ogg to playable format

Code: Select all

revorb 395891.wem.ogg 395891.ogg

Hello everyone, if anyone still have the client and willing to upload private on google drive or something to download, i would really appreciate. I am a newbie 3d artist, and i really want to learn more about the models ,environment etc, have no intention to spread the models or anything that would hurt IP of this game. Please pm me the link to client if you have, thank you!
