Ps2

which version of alchohol is suitable for making ps2 back ups ??

The latest version is (almost always) the most suitable. :wink:

No version of alcohol is NEEDED to copy PS2 games.

Any burning program will copy them. Nero, Roxio, even the ISO wizard from Microsoft.

There is no soft-protection on PS2 games, and there’s nothing strange about the discs beyond the physical protection for which you need a mod chip.
