|The NES Advantage.|
The special features on the NES Advantage are the Turbo and Slow switches, which to my knowledge were pioneered by this mother. Turbo works when you hold a button, and the controller rapidly sends the input signal as if you were tapping the button faster than is humanly comfortable. Unlike the one-switch-fits-all turbo capabilities on most other third-party controllers, the A and B buttons each get their own turbo switch, so you can leave one on and the other off at the same time. In another rarely-seen function, there are also two dials which control the rate of either turbo input. Some of you may wonder why anyone would want to set their auto-fire speeds at anything less than maximum, but for old shooter games where you can only have so many bullets on the screen at once, it pays to experiment. And yes, it is fast enough for Track & Field II. The slow switch, on the other hand, rapidly and automatically presses the Start button to simulate slow motion. It only works on games that use Start to pause, and works best if doing so manually freezes the game instead of taking you to a menu. The problems with using this is if you press something while the game is paused, it will not register, and in an admittedly minor complaint, you may sometimes turn off the slow function and the game will remain paused, since it was in its paused state when you turned it off.
|The Super Advantage.|
The turbo and slow capabilities are carried on to this controller - and then some. Each of the six buttons (A, B, X, Y, L, and R) have a corresponding 3-way turbo switch and fire rate slider (as opposed to a dial). Not only can each of the buttons be set to Turbo, firing repeatedly when you hold the button, but Auto, which sends the input command automatically. Meanwhile, the slow function has its own slider, so you can control how fast the Start button input is fired. Pretty much the only major drawback for some is the button layout. The L and R buttons are placed on either side of the main cluster (A, B, X, and Y). For games like the Street Fighter II series, which use two rows of three buttons each, this may be a hinderance, especially considering the fact that the new Sega Genesis controllers of the time used that 2x3 layout. This is far from a deal-breaker for me, though; I'm more concerned with the stiff construction of the buttons themselves, which, again, don't go in if you press them on the edge.
The used price for either of these controllers should be around US$20. They're real lifesavers... okay, thumb-savers for games which normally require quick button tapping, like shoot-em-ups that pre-date auto-fire. It could even help you with the obstacle course in Double Dare, where you have to press Left/Right or Up/Down rapidly. Both of these controllers have their construction flaws, but I highly recommend you get them if you can find a good enough deal.
