Most emulators have a cheat code entry option for you to enter cheats. Not all cheats work and not all cheat devices (ie gameshark, action replay) on the emulator will work either. I have heard that visual boy advance is the best emulator for inputing cheats.
NOT. but you can use cheats in visual boy in the menu.
www.gamefaqs.com
there are hundreds of cheats go to supercheats.com and search over there
Gameshark codes or console cheats
I do believe you are talking about the visual boy advance, if you are up at the top there should be an option for cheats you click on that and choose cheat list you then choose, add gameshark and you enter your game shark code
There are no cheats for gameboy, althoughthere are for visualboy.
Yes.
Pokemon Emerald is unsupported for Visual Boy Advance Link. Have you managed to trade? I am guessing not as you are asking for cheats. Try www.neoseeker.com and check out my Pokemon Emulation Guide. http://pokeemu.blogspot.com/

No. This specific emulator doesn't have any cheats for their games.
