The reason why it is faster is that you have a lower operation overhead for the 'emulator' since it is calling the hardware directly rather then having to go through middleware and wasting instructions/operations to translate the hardware calls.
The downside is that you have to know the hardware in and out to pull it off effectively and only work with a limited number of games.
