I am asking the same question everyone else is, and it seems that we arn't getting are questions answered, how do you patch or rebuild a game, and what are the difference? im sorry for being rude, its just that im frustrated with this process. the things i would like to know is: 1 what software do i need to use, that is free. 2 the guide to PROPERLY backing up a hard to copy ps2 game. 3 patch or rebuild,what is the difference? i go to ps2nfo.com and the chaos theory patch is not downloading for me a get a page cant be displayed window, is it me or the site? is it a cookie issue? Trust me i looked all day for a guide, and no luck for any of these pondering things.
