Also that Nintendo had hidden all this secret tech inside that wasn't used for some inexplicable reason until a dongle unlocked it.

there's some precedent for that though, they do that shit constantly, extra connectors and input methods that never or barely get used

there was one on the base of the NES, base of the Cube, the weird IR port on the 3DS that got used for the circle pad pro, the barely used camera in the joycons

according to this there literally was active tech in the Cube to enable optical 3D but they just never released the peripheral
