I was thinking more with "cheating" in mind instead of "piracy".

Oh and FYI there's no such thing as "pirated FFXI on PS2" because the HDD DNAS protection is vicious and the simple glimpse of modchip patching code on the PS2 memory makes PlayOnline freeze on a black screen at boot. Also you can't get the discs to install with a modchip on the PS2. If you can't install original discs with a modchip installed, trying to install copies with a modchip is moot point as you can't boot the copies without a mod chip... (lol it's the egg before chicken dilemma, no ?)
So no, there's no such thing as people playing FFXI on the PS2 with pirated copies.
