3. Launch "Winamp" (it can be downloaded from HERE) after installing the plug-in below in the resources section. This plug-in will allow you to read various video game formats in "Winamp." Import the audio file you extracted with "Trucha" into "Winamp" and export it into a playable format.
I'm not sure what the format will be but im pretty sure you can convert it to a flac file if it's not already in that format. Try here
Just so you don't make yourself get a headache trying to do it. I just wanted to tell you that there are only 3 tracks per song. Just like this picture.
As you could see(in the pic). On the harder levels there are only 3 buttons to work which coincide with the 3 audio tracks, so if you miss a "scratch" that audio track is silenced out for a brief moment(like any GH game). With all this said, you will get no acapellas or instrumentals out of it.
