how do i copy ps2 games on nero 6.6.just got it to day so don't know much.what do i do after i open nero start smart
I'm not too sure about Nero, but your best bet for copying the game to your hdd will be DVD Decrypter. You can then use Nero Burning Rom to burn the game to a DVD.
For burning PS2 games, I highly recommend DVD Decrypter to Mode, ISO, Read R and once it's done do Mode, ISO, Write W. Make sure you burn it at no higher than 4X with high quality media such as Taiyo Yuden, Verbatim and Maxell (made in japan). However, you can still burn PS2 games using Nero as well, but the real deal is to use high qualit media and don't go any faster than 4X.
