gta 3, wrc, wipeout no mod patches

[double2002]

i have backups of gta 3,wipeout(2 discs), and wrc i think they have been patched for the neo chip is there any way i can re-patch these for use with the card swap trick? or at least extract the files i need then patch?
sorry if this is a stupid question but im a complete newbie so if anyone knows of some easy to follow no mod patching instructions that would help as well
cheers
