could someone clarify for me please

[roman]

I've read through the forums about patches, pal/ntsc, images, etc..., but none I don't understand what is needed for a copy. I have chrono cross but I want to make a copy of it. I did a cd to cd copy with nero but it didn't work. I've got ppf o matic, but I can't find ppf patches.

Do I need to use a pal/ntsc program like pal4u even though the game is from the same country? Do I have to find a ppf patch? Do I need a mod chip to play copied games. If someone could help me it would be great. thanks
