Internal battery failure
A problem found with this cartridge is that the internal battery can fail after a few years. The internal battery allows the game to save the user's progress. It is possible to replace the battery, but the cartridge must be opened and a new battery must be soldered in. The battery model is similar to a model CR1616, and can generally be purchased at electronics stores. However, the internal battery has small conductive tabs spot-welded to its exterior, making the battery difficult to remove.
