TO SPOOKY - I think boot cd does work without modchip.

Now that's not true since a psx will not load a backup game since it recognisez that it doesn't have protection and stuff but here we're talking about a boot cd which is no game and the cdr is just a normal cd like each other. If you burn a music cd in a cdr I doubt the psx is not gonna be able to play it.
