Seriously? I thought that using ROMs/ISOs is legal pretty much everywhere as long as you own the original, and use it for personal uses. Must have gotten my facts a bit mixed up. Still, it should be OK. The fact that it's pirated isn't your fault, after all, and you did pay for the game.
In any case, just trying to help, not publicise pirating
Here's a suggestion though: you could pop it in your PC and see how that handles it. If it manages to read it (which means it isn't too badly damaged), you might be able to rip your own ISO from it, and then burn it on another CD. Still, as Previous said, you'd probably need to install a modchip or something, which is still pretty troublesome.
If your PC's powerful enough you might be able to run your ripped ISO with an emulator though. The only problem is that you'll have to use your keyboard, unless you have a PC controller.
