Has anybody had any success with the saving feature for the gateway cartridge? I've tried a few games, e.g. Luigi's Mansion and Shinobi. I've been using the procedure outlined, i.e. selecting home and then close. Luigi's mansion creates a file and this can be seen when loading it back up, but it starts at the beginning of the game. Shinobi doesn't even recognise it's saved a game when you restart it.
