You need a ripkit. These can be obtained from
www.alucard.cc and you will need a MINIMUM of a DVD-ROM drive to be able to read the DVD Games. DVD ReWriters are down to about £105 now or you can look on ebay for one - they have some great deals there. Ripkits usually need more than one CD-R and may span 3 or perhaps even 4. You will need to swap them. (To me that's a pain in the arse). Also, ripkits cut bits out of the game occasionally such as FMV's or videos to you and me.
Also, you may want to look
here for some helpful PS2 advice and information.
Hope this helps...
