Emulation is the process of imitating something.
In this case, it is imitating a console game. I offer the emulator download, as well as detailed instructions on getting it to work. Our goal here at Dr. Emu is to make things easy for you. We'll provide you with the latest emulators as well as the best Rom sites on the entire internet. Roms are the actual programs that people have taken from the console games.
