All easy to do - once you do it once. There is a good youtube video on how it's done by a user. Just join the forums for help/advice and downloads of others efforts. In a nutshell, you just download the original sound mix from the forum onto a usb. It is originally a zip file, which can be used directly in the pinsound board. If you want to sub anything, you unzip it, and have a series of 4 folders (music, sfx, voice and extras). The files are all .ogg files, which you can convert to .wav files via freac (free downoadable audio programme on freac.org). it's then a simple matter of looking through the songs, and cut and paste new .wav files that want into the individual folders in music. Don't have to convert lengths/bitrates etc like in pinball browser (which is a great programme for Sterns too!). You end up with hifi stereo sound straight away and as said - night and day difference.
