A non-limiting example game system comprises a server and a plurality of game apparatuses, each game apparatus emulating a game program. If applying a predetermined instruction during a game, a game screen is captured and an image file is produced. Furthermore, at this time, emulator status information is uploaded to the server from a game apparatus. Then, the server transmits a URL indicative of a storing location of the emulator status information to the game apparatus. The game apparatus writes the URL as metadata of the image file, and uploads the image file to the server. Furthermore, the game apparatus downloads a desired image file from the server, and downloads the emulator status information according to the URL that is acquired from the downloaded image file. An emulator status of another game apparatus can be reproduced by reading this emulator state information.
