Get the PS2 professionally chipped. NEO2.2 or Origachip are recommended.

Use DVD Region X or Action Replay 2 as your boot disk. Then you swap in the backup game. Boot methods are described in tutorials on ####://www.ps2ownz.com or ####://www.psxcopyworld.co.uk or ####://www.sgt-dan.com . I use DVD Region X as it's very simple.

You might (not) need to upgrade your burner to be CloneCD compatible. Then all CD games can be copied with no patching needed. Tuitotials are at the above mentioned sites. CloneCD is downloaded from ####://www.elby.de and they supply a list of cmpatible burners on their website. Check your burner with the list on the site first; PS2 game copying is the same as PS1 - but try and avoid patching.

With that, and the notes a provided to others under the search heading "NEWBIE" you are equipped and will flourish.

Good luck.
