Cheats. If you're using emulator, go search for GameShark Codes Emerald and click supercheats.com or something like that.

Not possible, while you can get a Emulator like Dolphin. if you don't know, an emulator tricks your computer into thinking its a wii. of course, this wont harm your computer in any way, close the program and the computer will be like it was. but, an emulator needs ROM's which can be hard to get.
