Firstly i am newbie in the forum and couldn't find a suitable topic for my problem.
I've just bought a copy of pokemon sapphire. Yet I could not enjoy it because my save file is deleted everytime I eject the game cartridge from my ds lite system. Also the same thing happens when I change my gba game or play the ds game. Unlike others' problems, this doesn't happen when i continuously save and play my sapphire game.
How can I overcome this problem? Is this problem due to my console or the game itself?
