In Emulators / NES ROMs

Ok, i downloaded a sNES ROM video and.. it doesnt load. Has any one had any problems with these?
Hi by the way.

Hello!
Welcome to the forums.

It would be good to know what emulator you use. If you told that we could find the problem more easily perhaps and maybe help you.

Oh. right. I forgot. I use Zsnes and i downloaded them from zopha.net
Hope ya can help me.
