But Citra VR came out for Quest 3… Playing 3DS in 3D, at 1080p for 500$ all-in. And the screens can be whatever size you want and wherever you want. You could put it 20 feet away and through a wall if need be. The eyes love when stuff is 20 feet away, very comfortable.
And before it was available as stand alone on the Quest 3, it was available on PCVR, with any computer strong enough to run the emulator. Which could be similarly pretty cheap. Like a raspberry pi or some such device.
It is also technically available on Quest 2, but you’d have to go lower than 1080p on most games. But still higher than native. Native was 400x240 for the 3D screen. But Quest 2 lowers the all-in price to like 300 dollars. Assuming you are buying new. Used would be cheaper.
