Emulators and ROMs...

I just got my NES and SNES emulators, but I'm having a huge problem finding ROMs...(yes I know I'm a little late...)
I found FFIV alright, but I downloaded FFVI and FFI only to find that I could not select my party in the beginning of FFI (won't select) and FFVI played the beginning sequence over endlessly (also no select/start option). Help! Can someone please tell me where I can find a ROM that works or does someone have the ones for FFI-VI that you can perhaps send to me?
Thanks :)

P.S. I'm new. Hi everyone!
