patched games need modchip too?

[deraleakmyballz]

I was playing around with patching a psx game (croc2) and the PS still says to "insert a playstation game" (PS5501). I still have not defeated my first psx game so please help! I am working on Croc 2 using cdrwin, and the pal4u, and pal2k. Do I need to have the mod chip and have the game patched?


Thanks
