There are a few errors I came across in the joystick pinout pages-
1st, in the atari 2600, for the paddles, #5 is listed as Not Connected. This should be paddle 1
second, in the old page for nintendo controllers, the colors are messed up for NES. data is yellow, clock is red.
Just a heads up... Took me a while to figure out that NES one :o
Also on the new Nintendo Controller page, pin 7 for the NES is listed as both VCC and Data, and on the SNES pin 5 is listed as P/S and Clock.
I believe that the SNES's pin 5 is P/S (or Data Load, Latch) and pin 6 is Clock.
