There's nothing worse than turning on your Gameboy to find that your beloved and hard-fought Pokémon collection has been erased. In the second generation Pokémon Gameboy games, an internal clock has been added to the infrastructure of the game. This feature introduced the availability of Pokémon at various times of the day, such as Hoothoot at night and Pidgey in the afternoon. Due to the game mechanics suddenly keeping real time, as well as days of the week, the internal battery inside the cartridge has an average of a seven year lifespan. The first generation Pokémon Gameboy games have a fourteen year battery life, compared to the decreased lifespan of the second generation games. After the battery has given up, the save file will be permanently deleted, and it will be impossible to save a new game. This is a major bummer, to say the least.
Fortunately, there is a solution, albeit a technically difficult one. The internal battery can be replaced, and we'll show you how we did it.
