Difference between Import, backup, and copies

[youssefmerjaneh]

Hi all,
My brother was in Syria, and bought me some PS2 games (not original).
I am thinking about a ModChip, but my question is:
what is really the difference between an Import, a Backup, and a Copy ... ??? any clue
well I have another question: I have seen Swap Magic Cds for V7 PS2 consols (I have 390004) But they claim that I have to plug in a non-solder Mod Chip, .. well I can't find a Non-Solder Mod Chip for V7, .. do you know where I can find that ???
and will I be able to boot all the unofficial DVDs ???

Thanks and regards
