It's a roughly 20 step, complex process explained clearly in text and screenshots; i don't think a video's going to make it much easier. You're welcome to try, i guess. Just don't go into it expecting to wind up with a video that makes it all look quick and easy.
Yeah this is to much for me right now just to add music. Plus I have hundreds of songs I like to go through. Having to convert them all to WAVs is to much in itself. Then I figure I can only listen in the car. So I just play them in VLC Player and adjust the player levels and game audio levels to where I can listen all throughout the game and still hear the effects and voices in the game. Works good so far. Tried VLC "hotkeyes" but they only work when the player is "selected" on the computer screen not when the game is playing.
Thanks
