ISO problem

When I tryed to play my Lunar Silver Star ISO the thing wouldn't work. I have every thing set right and I'm wondering if the ISO is corrupted...If anyone can help me with my problem, or knows where I can download a new copy of it I will try and repay you...Thanks for your time...
provide more information such as what emulator are you using how do you have the mp3s named.

and don't ask where to get isos
kega doesn't support the mp3 format, convert them to .wavs

or make sure you're using a burning prog that does it automatically when you do a multisession
