If you received one of the demo disc that erased your memory card for PS2 this is good news for you!!!

American gamers affected by the problem - or simply in possession of the PlayStation Underground disc in question - are being encouraged to contact SCEA (1-800-345-7669 via phone), who will then supply an address to send the disc to. The company is safeguarding the scheme against opportunists who might exploit it by limiting it to one game per PS2 serial number.

You can trade it for one of the following:

Athens 2004
ATV Offroad Fury 3
Gran Turismo 3 A-Spec
Hot Shots Golf Fore!
MLB 2004
Parappa the Rapper 2
Sly 2: Band of Thieves and Wild Arms 3

Thanks. I passed this on to DH, who plays Playstation with several of his friends. I don't think he had that disc, but, one of his friends might have.

Thanks!! Ron is calling on it now. We rec'd that disc, it erased our memory card, THEN we got the little postcard that told us not to play it or at least take the memory card out before playing it. Great timing! Arghhhh.

Thank you though... we'll definitely be going for this. :D
