UURGH!! swap-trick problems

[coyotefunky]

I've got a french ps2 console.
I didn't put any modchip inside, that's the reason why i use swap-trick method...
I burnt lots of games and many don't work...
However, i 'm sure that my backups are OK (using CDRWIN)...
For example, none game from Activision works.
Most of them launch at start then freeze into black screen.
If someone know what's wrong with my method, tell me quickly please, i'm very disapointed.

Go on your keyboards ! .-=|[ CoyoteFunky ]|=-.
