Um Jammer Lammy! How to Anti-MOD?

[Bahamut2002]

PLease! Help! I cant play Um Jammer Lammy!

It is the PAL european version and i cloned it. I cant play even with the original game! I have a psone PAL modchipped.

All my games work except for that one, um jammer lammy shows that red sign screen in japanesse letters. i think thats MOD-protection.

How can i bypass it? There are no gameshark codes for PAL version.

And the patch i find from "Chen", i tried it it patches ok, but when i burn it the game doesnt work on m psone...

So what can i do? Any way to **** up the mod-check?
If no gameshark codes, and the patch isnt working what can we do?

thanks! =)
