Even on more modern Pokemon systems (nintendo DS) you could upload a pokemon to the cloud servers and watch the network traffic lights on your router. Shut off your DS as soon as your pokemon had been uploaded and when you start up your game again, the pokemon is still in your party. It's also in the cloud so you connect and pull your clone off the server.
