AR2
 

What is it???
I wanna use backups on my ps2 but dont want to pull it to bits.

Ive read a bit about swapping the disks when the ps2 is switched on, but apparently I need a AR2 disk. I dont have one nor can I find a place to d/l it.

Please help!

Sorry there mate, but like most things in life nothing comes for free.
If you want to play backup games on your PS2 you'll HAVE TO get a modchip installed and BUY an AR2 disk from a shop (a downloaded & burned copy is no good - IT has to be the original).
There are other ways to play backup games but this involves mutilating your PS2 to standards far worse than having a simple mod-chip installation.

The above information is fact as many people will tell you (only ignorants would suggest the alternatives)

Ahhhh. Thats all I needed to know. That you can buy it in a shop.
Cheers dude.
