How do you ennter a cheat code for Pokemon Emerald vba on mac?

I deleted the old answer because it said to just buy a new computer.

To play Pokemon Emerald using the Visual boy advance on a Mac here are the steps. When you open VBA and it asks you which game to open, click Cancel. This does not close VBA. Go to options of VBA and click Add codebreaker/GameShark codes(they are unable to be used while a game is on this is why you click Cancel). After you enter the codes click Ok. Then go to Open Roms and choose Emerald. To activate the codes I have found you must press a combination of keys similar to no$gba. These keys are Left and Right Option buttons on the keyboard along with the Left control button. I'm not entirely sure how it works, but it's the only solution I've found.

Warning: The codes for Emerald are really buggy and crash the game frequently, by exiting VBA it will remove the codes and your game will be normal.

The only codes I've found to work are the Pokemon modifiers on Supercheats.com

Hope that helps.
