If this goes againts forum rules im sorry i didnt know, and yes i did read them and i dont think this applies.

Is it possible to burn DVD ps2 games, and play the backups on a moded ps2?

Currently I have a ps2 unmoded and my FFX got so scratched i had to buy a second copy because it wouldnt work anymore. Id rather just buy the games i like and play the backups so that i dont jepordize my games.

If anyone could tell me what i would need in order to make working backups of ps2 games id be really appreciative.

1.What kind of mod chip would i need, and where could i get it.
2.Would i need a dvd burner?
3.Would i need a gameshark or similar product.

Thanks!!
