Backup Procedure NTSC-PAL

[phil7071]

Hi,
If have a modified PAL PS2 gameconsole with DVD Region X but i can't play orginal import NTSC games?
I've been told to make backups of these games and the will play!
I tried many ways to burn but after booting (startup) the screen only turns black. What can go wrong, or who can tell me the proper procedure to create a backup from orginal NTSC which play on a PAL system.
