Loading State (freeze) from ZR or ZL on Classic Controller

Describe the enhancement desired or suggested change:

It would be nice to have an option to switch on quick Loading or Saving of 
Save States via the ZR or ZL buttons on the classic controller. Could also 
be done with the Right Analog stick by pressing Left. On the Cube 
controller could be loaded with the Z button.

On the PC emulators, there is quick loading and saving without having to 
go to the menu, just by hitting a key on the board.

Perhaps the loading could be preset to the number 1 freeze via ZR. And the 
saving could be preset to overwriting the number 1 freeze as well via ZL. 

So this quick load/save can be optional (turned on from the menu) or not 
optional.

Still, would be great to have so that the menu doesn't have to come up all 
the time. Consider that when the menu comes up, you have that annoying 
sound change at random. Well, with quick loading and saving, you wont have 
to worry about that changing of the sound any more! You also wont have to 
worry about crashing into a code dump! So this method of quick load/save 
would be AWESOME! (and quick and easy too I might add)
