I downloaded and converted a video of the Wario Land game in 3D and played it on my 3DS. People's worry about eyestrain are unwarranted. Think about it though, why did the Virtual Boy hurt people's eyes? It used shutter glasses, like the ones in most 3D TVs but much slower, so there was a constant flickering. That, combined with the colour pallet, was what hurt your eyes.

If they did it on the 3DS the problem wouldn't be there

Yeah, think of all those quality games no one got to play like Wario Land and...um....yeah Wario Land.

All you gotta do is repackage the games into color (or at the very least, black and white) and rename the games. That is all. Even so, though, I'd only pick up Wario Land.
