new ps2, whitch can read dvd+rw

[canyon]

hello i hope someone can answer my question.
if i buy a new ps2, whitch can read dvd+rw and -rw, does it work if i simply burn game backups on a dvd+rw, or is there any more copy protection on the original ps2 games.
i want to know, if i need a modchip, too or does it work, to burn simply on a dvd+rw to play whith the copies without a modchip.
thanks
