What kind of patch should I use to backup my ps2 cd games?

My problem is that my cd writer is not compatible with cdclone's subchannel writing so I can't use it to backup ps2 games. Then I think that I should patch the games by using cdwin, but I do not know which kind of patches I have to use and where to find them. Moreover, I would like to know if I can do copies from other backups and which program shoul I use. (for example: I have a gta3 backup, how can I copy it without using cd clone?)
