Hello. I got a Pokemon Ruby Gamepack(Original). I have that pack at least 1 year and it worked perfect until my game has been deleted. 2 weeks ago, I put the pack into the GBA. Switched to ON. but the the save dissapear. this is what the game writed:"The internal battery has run dry. The game can be played. However, clock-based events will no longer occur." so I understand the problem is with the clock. is there any way to fix that problem?
