How do I add my own songs to worms. Instead of the one it already has.

make an image of the CD, use magicISO or something to edit the image, replace the music files with your own (must be wav files at the same settings as the original files with the same file name too) and save the image and burn it, im not sure if wkfileoverride can help with this...

best to turn off ambience and use winamp or wmp or something in the background...

Ok the image thing worked.:) But do you know how to turn my music files into .WAV

dbpoweramp music converter

google it and see if it works...

I second Bonz' suggestion if you want a software solution, Audacity also allows you to edit the songs as well.

However, if you're looking for a way to simply do JUST a conversion, you can do it online at http://media-convert.com
