first off put it on a dvd-r or dvd+r, rw kills the laser

you need a mod chip because a un-modded ps2 can tell if its an original ps2 disc or not and the mod chips tells the ps2 to ignore the disc check and load the game.

the only alternative involves shoving a knife or card into your ps2 and that screws up the gears and stuff inside the ps2 making the cd tray no longer eject

get a mod if you feel you cant put one in yourself then send it to someone like sped and have it done, he did mine and it works great
