can someone explain how to change audio tracks from a cd into adx format. adx is the format for dc music and i wanna replace it with my own. im gettin vexed. ive spent the last couple of hours asking at diffrent sites and still havent got an answer. also whats the best application. the one im using wont even let me change adx files from diffrent games and its pissing me off.
