Dreamcast emulators and games on this site

Help

On this site:

I have downloaded both dreamcast emulators and three different games and I can not get the games to load.  I downloaded redream and the games I downloaded don't show up on the screen when I try to access them in the emulators library.  

Are the roms on here not the right kind? Am I extracting them wrong?  I can't find any literature either.

thanks for the help
