ok this is weird seems like older games that have music tracks if you play with iso then you don't get the music. I tried SF Alpha and Darkstalker and they exhibit the same problem. O well i guess I'll just ply from the cd then. Loading time ain't that bad =P
jitter correction is used for smoothing out audio from a cd since it may get a bad read on that bit/byte and it uses jitter to "average" what it should be, give you audio without noticeable skips and such. That's the basic idea at least, I could be spelling it out bad though. Jitter wouldn't be killing your music in this case though. Sorry no suggestions, except maybe try a different cd reader, and/or a different program for creating the iso though I use cdrwin too and it works just peachy.
