can't play DVD9 backup on my...

[dacornholio]

i guess i have a pressed?
not too sure... i had a original copy b4 as a gift..and i did finish MGS2 already (not substance) i sold it on ebay because my friend said he can get me a backup (or if u guys call it pressed) of the game. anywayz so there is no way i can play that?


what if i switch my modchip to some that doesn't need boot disc, would the game work then?


thx
