Can't play backup with Jap PS2

[Uranus1]

I downloaded Batman Vengeance and burned it on an 80 min. CDR successfully. Then I applied the Universal PS2 patch so I can do the swap trick on my Jap PS2 (model 10000). But it doesn't seem to work, how come?

I've noticed that if the game has been ripped from a DVD to a CD, it doesn't seem to run even with the Universal patch.

Help anybody?
