Nes/SNEs Pinout error

Looking at the great info on the above link I am at a loss.

Your site was the exact thing I was looking for to convert a Nes controller to work with a snes or even a snes USB adapter.

However reading the info at the above link I am either not getting it, or there is an error.

Pin Name NES Pin # SNES Pin # Famicom Pin #
GND            2                   1                 8
P/S             3                   5                12
Clock          5                   6                10
Data           7                   4                 11
Vcc +5v      7                   7                 9


The problem I am seeing is this. According to the chart the nes pin #7 is connected to both the Snes Pin# 4 & 7.

I am thinking that�s a typo. However the only pin I see missing on the nes side is pin #1 (which makes a typo perfectly plausible) but I still can�t get it to work.

Can anyone chime in with laymen�s terms if possible and explain it to me?

My good man, I don't see what you have explained, I only see it listed as pin 4 for snes. Perhaps you are just reading the chart wrong, eh?

he's right, that chart is actually somewhat wrong.
This link http://home.freeuk.net/markk/Consoles/SNES_Controllers_on_NES.txt shows how to wire a snes controller in order to use it with a nes console.
I tried to create the same thing using the reference from Gamesx (http://www.gamesx.com/controldata/nessnes.htm) and it didn't work.
I guess there's something wrong with the chart...or well, maybe I'm just reading erroneously the images on the left

lawrence, is this being fixed?
i've done that conversion aswel, and it workes, so id say mark knibbs has it pretty sussed. his pin numbering is completely diifferent though, so doing a comparison in my head is a pain.. but it looks like his entire pinout pretty much conflicts with what gamesx has.. and im sorry to say it but im leaning toward marks being correct.. but only cos the conversion works, i guess the pin functions could be wrong.

I'll try and transfer the stuff to the wiki today (I thought it had been done already?) where it can be updated with proper numbers.  FWIW the info that is there came from the Japanese GameLab magazine.
