Click "Browse" to select a folder for the program to be saved in, then click "Next." Click or unclick the checkbox that asks you to create a desktop icon and click "Next" once more.
Click "Install" on the next pop-up window. It should take anywhere from a few seconds to a few minutes to install to your computer. Click "Finish" when installation is complete.
Connect the larger USB cord included with GameShark onto your computer, then insert the DS game card, to be used for saved games as well as back-ups, into the slot at the end of the USB connector. When you plug the DS game card into the USB slot, the GameShark start-up menu will appear. Copy from PC to DS (and vice versa) using the GameShark interface that appears after connecting via USB.
