You still need a large toc game for dvd, then you need to perform the swap with the dvdr.
By the time you have paid for everything (Gameshark, fliptoplid, hammer for case

) it would cost MORE than getting a mod installed which does it already.
The swaps have been known for years now. Nothing new exept instead of sticking a knife in the drive you are putting a chainsaw to the case.
And as for ps1 originals then you don't use the swap magic disc to boot them :S
