How to boot NTSC dvd backups
 

i am trying to boot up a backup of FFX which is Ntsc on my pal ps2
how do i do it with an AR2 and a usb modchip

No - USB modchip is useless.

Put in an Origachip (www.origachip.com) or a Messiah (which you can get from me - e-mail me through my profile).

Cheapest solution of the above two is origachip - a very fine chip, uses a single swap with AR2.

The Messiah is better because it is fully no swap.
