My son has been given this game by a friend of his, it looks like a copy to me as the disc is the wrong colour, it doesn't work, any ideas anyone.

PS One is not my scene, but in principle to play a backup, the PS needs to be chipped for that purpose. See www.megagames.com for more infoo, tutorials, chips, etc. Or Playstationmods.com

I think he had it chipped if that is what you call it,he has played copies before

Then it has to be a bad copy.
