can someone tell me how you know if a copied ps2 game needs a patch

Depends on what game, what region, and what modchip you have.

im from uk & have been told that copied games work with action replay 2 disc, so u dont need ps2 chipped, any ideas

cheers

You can play discs without a chip but it is has a high risk of damaging your PS2. It involves prying the drive open with a screwdriver. Most non-solderchips will play all the games you need to. Depending on which one you get out of region games and\or EA games may need to be patched. Non-solder chips will also require a Action Replay disc to boot up with. Best way to go is a solder chip. Plays anything, any region with the swap disc and no patches. Best one out there is Messiah 2.
