psx rom burning

hi i tried to burn an image of resident evil 3 with alchohol and the image burned perfectly and smoothly but when i put it in my playstation1 it reads "please insert a playstation rom". What am i doing wrong? do i need to burn something with it like bios or something?

Do you have a mod chip installed on your PSX console?

If not then you need one in order to run a copied game.

no I dont, are they expensive? thnx

Find a gaming store, they usually sell mod-chips.

This may help you too.
