The Japanese 3DS was given a teardown in the US on Thursday by iFixit that revealed a very intricate build. Despite having an easily swappable battery and standard Philips screws, Nintendo's system was found very difficult to fix since there were many small parts that could easily break. Ribbon cables were wrapped around the 3DS' inside by robots in a way that a human couldn't easily detach, and many of the connectors use zero insertion force (ZIF) sockets that make it hard to tell if it's plugged in until it's completely reassembled.
Nintendo's 3DS may have been spotted in crude form through an FCC filing. A test board for the "DS CTR" doesn't show the design by itself but does show at least one widescreen display. Most of the components are hidden in the filing, submitted by wireless supplier Mitsumi, and prevent easily identifying whether it's using a new Tegra processor or other new hardware.
