clonedvd is probably not the one to copy ps2 games.:disagree: its for copying/compressing movies. clonecd is the one to use for a 1:1 copy,:agree: though i dont know if it will make immediately playable copies of ps2 games. (due to hardware copyprotection)
I believe alcohol 120% can copy ps2 games. (again i dont know if they are immediately playable)
i do not know if a modchip or other protection-bypass is needed on your ps2 to play copies (like on xbox or gamecube). ps2 games are a lot easier to copy (xbox and gamecube disks arent readable in a pc cd/dvd drive, ps2 disks are) but i dont know if you need anything other than a copied disk (modchip etc).
