The 3DS added glasses-free stereoscopic 3-D to a dual-screen handheld, using a parallax-barrier top screen you could dial from flat to deep. Behind it sat dual ARM11 cores and a PICA200 GPU; the headline trick was the autostereoscopic display, later joined by a depth slider and an analog nub.
The Four Natures
each piece emerges by one of four natures
The Idea
the three-beat story
The top screen uses a parallax barrier — a layer that sends slightly different images to each eye — for stereoscopic depth with no glasses. A physical 3-D Depth Slider lets you increase, reduce, or switch off the effect.
Two ARM11 cores (plus an ARM9 for compatibility) and a DMP PICA200 GPU drove real 3-D games on both screens, with the lower screen remaining a resistive touch panel as on the DS.
Outer stereo cameras could capture 3-D photos, and a 'Circle Pad' analog nub finally gave the handheld proper analog control — with the later New 3DS adding a second nub and more power.

The Reckoning
the teardown, and the honesty about it
The Domain: Open It and Spec It
the teardown
- EXEREÚNESIS takes a real, made machine apart down to the chip and writes the honest spec — not a story-world but a technical anatomy.

Two-Layer Honest
datasheet vs lore
- Settled: the dual ARM11 + ARM9 CPUs, the PICA200 GPU, the parallax-barrier autostereoscopic top screen, the Depth Slider, and DS backward compatibility are documented.
- Flagged: the glasses-free 3-D had a limited 'sweet spot' viewing angle and caused some eye strain — stated as the well-known limitation, not hidden.
