N64/Snes Emulators for Wii

WHat emulators should I download so that they will work on my Wii?

I'm pretty new at this so some help would be appreciated

Do I download the emu, install it then copy it onto my SD card? I have the homebrew channel installed on my wii - will this read the programme?
Also will I just copy a bunch of roms onto the SD card for the emu to read? Somebody mentioned WADs but I dunno what these are or what they are for. Thanks

Go here:

http://wiibrew.org/wiki/Index.php

and search for the emulator you want.
It has plenty of info on how to run the emulators.

Thanks for the link.
