PS2/PATCH TROUBLE !!

[EiznuV]

WHOAAA!!! Is there anyone out there who can HELP !! me.
Thinking this is THE place to be to get my problems solved
But had no reaction yet ( maybe i want to fast )
Here's a replay of the message i posted before about Crash 5

*** Didn't seem that difficult =-)
But when i arrived to meet the boss of level 20+ in Crash Bandicoot - the Wrath of Cortex - (5)
It didn't go as i acspected to, the Game froze up on me !
And no matter what i have tried , it FROZE on the same spot. ( so simple me is thinking , ah ! a copy protection !? , or just burned to fast !)
So did burn it again on 2 and 1 SPEED =-)
But stil no result !! Have read all on here and did find nothing !!
SO WHO CAN HELP ME !!! ( maybe with a working iso ? )
or just The sullution to patch or something !!

have a ps2(30004) chipped with a Neo 2.2/Ar2
The Game is cracked by Kalisto ***

Anyone who could give a hint ??
Thanx in advance.
