Right as the otherone is a hoax, Another one has just been released and from the 2 people i know that have tested they got this working.
From the NFO:
Alright, this is in fact a working boot method for backups!
This is the demo disk, with a little edited code, here is how it works... Select one of the following demos, when into the boot disk play for approx: 1 minute, then stop and eject the disk,(using the center X in your controller), swap with your backup title, DVD using one of the dump tools from PI,hit the x to return to the dashboard, and viola your in! P.S. Fuck MS, You earn enough from systems. Shortages... come on now ? Here's to keeping knowledge free, in this world... Tested with PGR3 Backup, thanks to PI for the support, Happy New Year, To the Teams, Keep the net Free ! See you in 2006 !
