I don't believe there is a way to download the legit games on that site, but you can play the arcade games they have available if you have a flash player, if you want to download the actual games say like 3rd gen games that are available, you would need to download a VBA or a VBA-M(for mac users) and pic out which game you want to play by downloading the zip file for that said game. this program also works for rom hacks but they will only play if the file says .gba otherwise VBA will close on you. sorry for the extra info, just thought it would be of use.
