The seal sticker was already half peeled off, so I helped myself. The controller was never opened, as the screws were still locked.

Mine has the GC plug. It is compatible with the console but it's limited, and you'll see why...

Seems like Nintendo tried to limit the controller's usage by soldering the contact pads. That means the X, Y, B, D-pad and triggers are always pressed down, which limits its usage to the sticks, A button and Start/Z.

See the triggers' digital contact pads.

And now it's back in a display on my shelf. If you have any questions feel free to ask!

Really interesting that certain contact pads were soldered down to force held inputs. I wonder if that's common place on these? I'd like to know if this is also present on the proto controllers that have the plug input for the Dolphin dev units instead of the actual GC plug.

But yea, this is basically a grail status item for me. Thanks for sharing the tear down of it!

Awesome tear down and I can see the controller is hand soldered.

The two protos I've seen with an adapter works properly, so I think mine could be a special order from a dev team to navigate a menu or something. I've also seen one like mine but missing the X, Y, B and D-pad but they still work. Funky stuff

And yea, that's one of my holy grail too. I wish I could collect all the prototype variants but I think I'll settle for ver. A and ver. B, if I can find one!

Are you sure that's solder ? Looks more like paint marker.

I wonder if it's for repair. Maybe it's conductive to try to fix response issues. Just a wild guess.

I'll have to see tomorrow. The substance is metallic, shiny and conductive so I'm leaning toward solder.

From the look of it, it's silver-loaded paint. It's also interesting that all 4 points on the D-pad are linked, which corresponds to an "all directions at once" condition that is normally impossible for the controller to generate. There have been a number of times when Nintendo have used this as a signal for entering some sort of check mode, though. And that controller is marked "NR DISC CHECKER".

It's possible the buttons have been forced to a configuration that boots some specific unit into a testing mode.

Very interesting, thanks for sharing! These are my favorite controllers. I can't wait to get my hands on one.
