About this video

In this video, I show in detail how to replace audio file inside a .pck archive for Mafia DE. I replace part of original main menu theme to Little Italy as a test.
Links to the necessary programs from the video are attached in the comments below the video on Youtube.

Unfortunately, I can't make a properly WEM file for radio and music from storyline of the game (i think some kind of incompatibility due to incorrect WEM file in Wwise). But I hope my tutorial video will help other people and they will be able to return classic music to Mafia DE.

I recommend doing your first replacement on the same files shown in the video to make sure you're doing everything right.

But what is next... a little hint for you:
Music from Running Man (analogue La Verdine) it's a File0163.wem inside  \edit\audio\packages\audio_global_events.pck
It will be easiest to test the replacement on it, because if you can create the correct WEM for this file, you will most likely be able to create the correct WEM for radio tracks.

Do not forget that the weight of new files must be equal or less than the original ones. The duration of the sound is also taken from the original audio file. That is, if it was 50 seconds, your new sound will also play only 50 seconds.
