AR2

[wildthing]

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)
