Some help pls
 

I'm new, and before someone started I have read most of the threads about GT4. I don't have HD in my PS2, I read that some chips play the backup direct from the disk like the infinite, but I can't even make a copy of GT4 to a DL disk, any ideas? (I have DVDDecrypter)

Play your original?? :D

I'm still smoking rolling tobacco, but if not somebody find out a way to back it up, I will seal it in it's case and hide it somewhere deep so my grandchildrens can enjoy this masterpiece

Seeing that you don't have a HD and no way to burn DL discs you don't have very many options left. If I am not mistaken there are no rip kits to downsize this game to a DVD-5.

I have NEC 3500 DL, I don't understand why not be able to make a copy, I think
I heard there are many that did it even if the game is not playable?????

I've heard that they are working on a patch that will let GT4 work on a DL disc... I haven't heard of the progress though.
