Ps2 backup?

can i backup my original ps2 games with alcohol 120% and then play the games without chip in ps2 ?

You can backup ps2 games with alcohol no problem but you will need a modchip or other boot method to play the backups…

Or a Magic swap card thingy.

why i cannot do an exact replica of ps2 game ?and then play without chip ?

Because the anti-piracy protection is too good. For this generation of DVD burner at any rate.

and why this “too good protection” is not at pc games ?

because you need special hardware to play it and it’s not with the dvd standard(I think)

Experts have been trying to defeat the psx/ps2 boot protection for years (and without any luck). See here for more information and technical details.
