Fear Effect 1 & 2 modchip detection?

[peaceb2usall]

Can anyone tell me if fear effect 1 and 2 have modchip detection. I play the orginal disc one to the end goto change to disc 2 and I get a "uknown disc format" error. How do I bypass this modchip detection?. Anyone know how the manufactures do this?. I have a 9## psx with a four wire internal modchip. Any help is appreciated no one seems to know about these games. btw it's NTSC.
