3DNes uses an algorithm to convert 2D sprites of the NES into 3D objects, bringing new life to many NES classics. This isn't a simple case of loading roms and playing the game however. The emulator requires the addition of a 3dn file that you can create yourself or download community made files at 3DN Repository.
The emulator itself works well with basic feature like support for controllers and save / load states.
Just for fun I tried the stereoscopic mode on my 3D TV. The textures are more defined but nothing on the screen actually pops out.
There is a Pro version ($5) that supports FPS (First Person Shooter) view and TrinusVR integration.
