ps2 help

i know ima huge noob for asking this and because im still using a ps2. but i recently got an .iso file and was able to mount it and burn it onto a dvd-r disc with toast (i have a mac) but when i put it in my ps2 it says to insert a ps2 formated disc. what am i doing wrong/how can i get these discs to work on my ps2? any help is greatly appreciated and feel free to make fun of me, i prolly deserve it.

you'd have to mod ur ps2 in order for that iso to work. u might wanna check out "pcsx2 mac" for this. not sure how well that emu is working though. gl.
