koitsu , I agree on the same basics - that you are also agreeing - but you lose the point when trying to justify things too much:

OFCOURSE the mold in both cases is not made to hold up at a pulling contest.
OFCOURSE if you pull like a gorilla you will rip off the the 360 controller cable and the dvd one. That's common sense.

The point of this specific part of this mechanical contraption is absorb pulling shock as best as possible while holding th cable in place, and YES it is implied on the 360 controller that it made to protect the connector inside like in all devices, this is self explained.
In both cases 90% of the time under normal circumstances when you stumble on the cable the device will sustain and tension will most likely express by the 360 controller unplugging from the console and the dvd from the mains. Then there is the chance the device will develop a fault caused by hitting hard on surfaces like the floor.
But this is enough protection as those devices are home ones, not military grade ones. If you want to "solve the problem sufficiently" you do not use thin plastic/metal parts or simple cables.

But saying that the mold is not made to deal with pulling stress because if you use excess force you can brake it, is not a valid argument. It's like saying that your pants are not made to protect you from cold because if you go to Siberia you will freeze. Everything has it's limits.

Thank you very much for the controller pinout! But does this support the four score adapter and zapper? Seems like you need to add atleast the (player 2) Joypad 2 D4 (pin 4) and D3 (pin 5) from expansion port. To make zapper work? Do i make the same connection for Joypad 1 (player 1) also? Or are the Joypad 1 D4 and D3 hidden somewhere on the board?

In the specific case of starting with an original plain Famicom motherboard: No, Joypad1 doesn't/can't have a D3 and D4. The part they used in the NES is used for something else in the Famicom.

To add D3 and D4 to joypad2, you'll need to jumper from the expansion port, as per http://famicomworld.com/workshop/tech/n ... v-famicom/

Thanks! That same diagram was the only thing i could find about the subject too.. But cause im making this with VGS Subor D21 (Famicom Clone), i was little confused about the Top loader motherboard..
I still need to figure out the Four score and Multitap difference problem. Seems like there is no easy, or best way to do it.
I think i try with both joypad wires and expancion port wires. And add switch for Four score or Multitap.
The Famicom Forum had some topic about the issue: http://www.famicomworld.com/forum/index ... pic=5912.0
So there is people who have done it. But i cant find clear instructions for this anywhere. I think i have to try make picture of the pinout for my self. To understand it better :)

The NES Four Score uses some kind of ASIC or PAL to emulate some combination of a 74'165, a 74'138, and a 74'153. The Famicom four-players adapter is an entirely passive device.

It uses an ASIC. I have one of these.
