I've been reading the playstation 2 backup guides and I know how to run dvd decryptor and dvd shrink. My only question is then does your playstation 2 have to have a mod chip in order to read/play the backup disc? If it does where do I get them? / what kind? / how much are they? and how do I install it? If I don't have to mod my ps2 what do I have to do to get the disc to play? my ps2 plays backup dvd's that've I've made with decryptor and shrink. I would like to leave my ps2 unmodded if it is possible.
