PS2 SCPH-30001 Question!!

[Savz]

Hello, I am really new to this stuff, but I am very familar with PS1 modding. I want a MOD Chip that will allow me to play CDR backups and DVDR backups of PS2 games. But I have heard that in order to burn a PS2 game that is a DVD game you need to have a DVD burner. So GTA3 is a DVD game? I am sort of confused. So in order for me to make a copy of GTA 3, I need a DVD ROM Drive and make a copy like that, or can I copy GTA 3 on my CDRW drive?

Thanks
Joe
