Thanks for the reply...

Yargh....  I was just about to post my findings, but you got to it first.
And the SCEA news server ran out of space.  :P
 
What I just found out over the weekend (with the AIFF2VAG included with
your Yaroze) was that it is possible to get looping to work provided that:
 
        - the sample is either AIFF or raw
        - you have the "-E" endian flag set for raw samples (I guess the
          PSX uses unsigned samples...)
 
I actually have been testing a S3M (ScreamTracker MOD) program I'm in the
middle of writing which will convert a S3M into a VAB and some sequence
data (my own file).  I found that if the number of samplings in a sound
sample aren't divisible by 28, then:
 
        - AIFF2VAG will pad the sound sample
        - you will get clicking, but the sound will play
 
Yes, I also use Cool Edit quite often for checking the length.  But the
utility I'm writing will print out the nearest 28-sample boundary.  :)
(That has saved a bit of time.)
