I've got here a few grey controllers (from different sources/sellers) with some kind of rubber thing in the plug end.

Does anyone knows what it is and it is for?

The one on the right i have and seen before. Common in early controllers released in PAL regions. I think it is an anti-static device. Some USB cords (like those for camcorders) have them here in the States.

Never seen the one on the left.

Hum... so in NTSC regions the controllers have none of these things??

Ah! I had no idea! Because I've owned tens of controllers and all of them had this.

So I guess Nintendo at some point just made some of them like that. It's a shame because it looks really cheap compared to the solid plastic ones.

"A ferrite bead is a passive electric component used to suppress high frequency noise in electronic circuits. It is a specific type of electronic choke. Ferrite beads employ the dissipation of high frequency currents in a ferrite ceramic to build high frequency noise suppression devices. Ferrite beads may also be called blocks, cores, rings, EMI filters, or chokes"
Source: http://en.wikipedia.org/wiki/Ferrite_bead

There are at least 3 different types of those on N64 controllers.
- shrink tubed
- TDK branded
- Nintendo branded

Every controller in Germany and probably the rest of Europe has them.

Its a untangler... if that makes sense.


Its meant to stop the cord from tangling... ive only ever got them from euro controllers. AU, US and JAP don't have them as far as I know.

We've referred to them around here in a very technical manner as dongles. :D I thought that they had to do with shielding (or containing) EMF signals emanating from the cord, but I'm no electrical engineer. Only on early controllers sold in the PAL region, correct?

PAL region only, added because of strict EU regulations regarding interference. And the correct technical term is 'kludge' :)

I've been wondering this my whole life.
I remembered when I was a kid looking at pictures of boxes/promos & the controllers didn't have that... but my official nintendo PAL controllers had it, I still have two of them.
So many year laters now I found out what it is, thanks!
I know this is an old post, but has anyone tried to remove this kludge? Is it even possible?

yes you can remove it with some force but it wil destroy the plastic casing so you can't put it back on.
My advice: just leave it there. A PAL controller _should_ have one and it doesn't eat bread as they say here in Holland.

Ferrite. A non-conductive compound

The one in the picture is anyway. Took one apart before. Its wrapped around the cable to dissipate any interference with the controller.

I'm pretty sure it comes with our electrical device regulations in UK it prevents static build up (and interference causing delays in inputs etc) and eventually discharging when you touch the cartridge or metal etc.

Even Xbox and Sony had to apply the ferrite beads to their controllers on release here:

It a nutshell it provides reduction on interference and ESD (Electro-static-discharge)

Have you ever waved a strong magnet across an analog (CRT) TV and seen the screen go all wavy?
Ferrite prevents this.
