We treat Pakistanis better in the UK, I'm sure!
Best way to create a backup of CD games is to have a burner that is 'DAO-RAW+96' compatible with
CloneCD. This program makes 1:1 backups (including copy protection) so no patching is required. It is available from
www.elby.de and they have a table of compatible disk drives.
As to modchip, the soldered mods make best use of the 1:1 copy. I recommend either Origachip or Messiah. These do no harm to the PS2 and they both do everything. Messiah does everything no swap, Origachip does everything and some of it single swap.
That's it.
