Moved to correct forum.
You don't need a patcher but if the disc is libcrypt protected you won't be able to copy it successfully with nero. You'll need to use either CloneCD or alcohol.
However, most playstation cds downunder have no protection other than the boot protection which is defeated by the mod chip.
To be able to help you further, please let us know what game you're trying to copy and what type of reader/writer you've got.
