PS2 Slimline Disk Swapping
Note! To do this, you must have first Enabled Disk Swapping on your PS2!

Ok, first load up the settings part of your ps (dont put a cd in and turn it on). Turn OFF Fast disk spin or whatever.
Done that? Cool.
Turn Off the ps and put a real PSX disk in.
Turn on the playstation, you will see the cd spin fast and slow.
Follow this guide:
The cd will spin:
Slow-Fast-Slow-Fast (PS Logo Here)-Slow-Fast-Slow-(Black Screen)-Fast-(Copyright Screen)
On the second slow, quickly pull out the real cd and put in the copied one.
On the third slow, quickly pull out the copied cd and put in the real one.
