How do you find Pokemon Emerald for Virtual Boy?
No pokemon games were made for the virtual boy.
There is a Gameboy Advance Emulator called the Virtual Boy Advance (VBA), on which you can play GBA games if you have their ROM. Just type in "vba download" into Google and click the first result that shows up. As for the the actual Pokémon Emerald ROM, I don't know a decent website to download them from, so you'll have to do a little bit more searching to find one.
