There are a few ways to use gameshark codes on an Android emulator. The first way is to use the built-in emulator features. To do this, open the emulator and type in the following code: GBAEmu.setGameSharkCodes( “GBA_SHARK” ); This will set up your emulator with gameshark codes so that you can play GBA games. The second way is to use a third-party emulator. This can be found on the Google Play store or at some online stores. Once you have installed the emulator, type in the following code: GBAEmu.setGameSharkCodes( “GBA_SHARK” ); GBAEmu.addGame( “Super Mario World”, 10); GBAEmu.addGame( “The Legend of Zelda”, 11); GBAEmu.addGame( “Final Fantasy VII”, 12); These codes will add new GBA games to your emulator and allow you to play them without having to set up any game codes yourself.
