Citra: A 3DS Emulator

Citra VR is a Nintendo 3DS emulator for the Meta Quest, bringing the handheld’s dual-screen, stereoscopic 3D experience into virtual reality.

You can grab 3D-compatible ROMs from Citra’s official website.

Since most 3DS games were designed with dual-eye 3D in mind, they feel perfectly at home in VR — almost like they were made for it.
