I need hep with nulldc

[tremonti132]

well i am new to the emulator thing. i installed the dreamcast emulator because i want to play sonic adventure 2. when i boot up the program it says
couldn't find bios--exiting. then the program exits. I heard about the dc bios but where can i get them. and how do i add them. and how do i get sonic adventure 2?

I am afraid you will have to find that out on your own, asking for the illegal bios and roms is against the rules.
