How do i burn my game image

Im trying to back-up my metal slug anthology, ps2 game. I got to the point where i got an iso on my computer but when i try to burn it onto a DVD+R it will burn but my ps2 says it cannot read it. I've tried burning the image to DVD+R with both nero and alcohol120, neither are doin it.
am i missing some converting or some other step

btw i have that small ps2, does that matter?

does yyour ps2 have a modchip installed? if not then its pointless

sure doesnt. can i even get one in a small ps2?

u got 2 modify ur PS2 first an den play burn games...check out d modchips online an check out where does modify PS2's close 2 u...after dat, den u can burn games an play

You have to mod it first.

It's way too much trouble and risk than it's worth. Just play the game like its meant to be, and legally.
