@noiob well it's certainly not easy to realize it's even an option to go looking for it!
It works on GBA and SNES, at least, VC titles as well. I would be surprised if it didn't also work for the other VC systems

@Felthry the 3DS still came with a manual ;)
it works for GB(C) as well, plus you get a border with a nice 3D effect. Makes the effective screen size tiny thouh
@Felthry that's alright, it's also not fully serious
@noiob i don't fully agree with that
