Ever wanted to make your own SNES controller? This little guy
can help.

It's a nifty little signal combiner for the SNES you can use to
hook up your own custom controller to the old gray beast.

Where you can find them is beyond me, but I've seen them in several
third-party SNES controllers. They're quite ingenious and very easy
to solder compared to the surface-mount chips used in official
Nintendo controllers. They're also compact enough to get around
the space problems of using to CMOS chips like the GamesX method.

## Notes ##

This is probably the most straightforward chip diagram on the planet.
If you're new to electronics, the corner of the chip with the small
indentation in it marks Pin #1.

All pins marked as X, B, L, UP, and so on refer to the SNES button
presses which are sent to the pin. SNES-1 through SNES-7 refer to the
pins on the SNES controller connector (starting from the flat side as
Pin #1).

As long as you remember that both your SNES controller cable and your
button presses need to share the GND pin and you’re all set.

I used this chip in my Super Dance Dance Gaiden controller project.
