I played with this all weekend..  The Yaroze never stops spinning the CD
from what I've been able to see.  So that in itself is a problem.  You have
to "Hot swap" the disks.

I wrote a routine that loaded the "system.cnf" file from the CD in the
unit, and "printf'ed" it to the PC.  After a disk swap, it would read the
file, and dump it just fine.  Soooo, in theory, you could read your data
files from the CD-R.

This isn't true.  I exited and re-downloaded with a different CD in the
drive!

Can't be done..  There is also the protection on the "Yaroze Boot Disc"
that is required for the PS to load anything.  This, I'M SURE Sony won't
give up!


Now what *I* want from Sony is a call to stop the CD from spinning so you
can swap them safely!
