who said u can't play GT4 with a mod chip inside..all u need to update the chip, go re-modd it that what i did..the GT4 game piratred version uses the new DVD called D-9 which most old PS2 mod chips won't work on..chips that are 3-4 years old won't work with GT4....but getting a new chip such as Magic 5 the new chip around can support the newest DVD D-9..so get ur PS2 Re-chipped if u have a chip 3 years or older...other wise..u don't be able to play Dual layer...i got the new chip for free..casue i know the guy at my Gamestore..
