Nintendo's Switch Has Been Hiding a Buried 'VR Mode' For Over a Year (arstechnica.com) 38

An anonymous reader quotes a report from Ars Technica: Hackers have uncovered and tested a screen-splitting "VR Mode" that has been buried in the Switch's system-level firmware for over a year. The discovery suggests that Nintendo at least toyed with the idea that the tablet system could serve as a stereoscopic display for a virtual reality headset. Switch hackers first discovered and documented references to a "VrMode" in the Switch OS' Applet Manager services back in December when analyzing the June 2017 release of version 3.0.0 of the system's firmware. But the community doesn't seem to have done much testing of the internal functions "IsVrModeEnabled" and "SetVrModeEnabled" at the time. That changed shortly after Switch modder OatmealDome publicly noted one of the VR functions earlier this month, rhetorically asking, "has anyone actually tried calling it?" Fellow hacker random0666 responded with a short Twitter video (and an even shorter followup) showing the results of an extremely simple homebrew testing app that activates the system's VrMode functions.

As you can see in those video links, using those functions to enable the Switch's VR mode splits the screen vertically into two identical half-sized images, in much the way other VR displays split an LCD screen to create a stereoscopic 3D effect. System-level UI elements appear on both sides of the screen when the mode is enabled, and the French text shown in the test can be roughly translated to "Please move the console away from your face and click the close button." The location of the functions in the Switch firmware suggest they're part of Nintendo's own Switch code and not generic functions included in other Nvidia Tegra-based hardware.

    Nintendo did this before everyone else, with the Virtual Boy.

    no, they haven't been "hiding" it. It was found almost at launch over a year ago. Nintendo even talked about VR as a possability during the NX-face in investor meetings.
    It's just code they didn't bother to clean up and remove when they decided to not do VR with the Switch.
    Most likely because of the higher resolution and frame rate that would be needed which would have pushed up the price significantly above where they wanted the device to land.

  • If it's just 60Hz it will not work too well

  • I sure wish they would discover a hidden save-file-backup mode, or a way to lock access to an account. It takes exactly 5 clicks for my toddler to delete my Zelda save game (home-zelda-dad profile-new game-yes) and as far as I can tell there is zero recourse other than not letting the child ever touch the system.

  • If you ever played Nintendo Land on the Wii U, you know it had a different sort of VR implementation - rather than strapping the display to your head, you treated it as a window to the virtual environment. This is such a better solution that the goggles thing: there's no barrier to getting into your game, you're not cut off from the world around you, so it's very easy to pick up and play and put down again when you need to. No motion sickness, no awkward controls (although those aren't strictly required for
