I've been hearing a lot about people losing their Generation I save files due to the game's internal battery dieing... I was wondering, is that common? None of my Generation I games have deleted themselves yet (yeah, my Generation II games have, but I figure that's because of the clock constantly sucking away the battery).
How much longer will they typically last?
Also, do N64 cartridges die as fast? I'm wondering, what would be the safest place to store my Pokémon (as I have 2 official Mews from the Pokémon 2000 Stadium Tour that I don't want erased)... should I transfer them to Stadium or Stadium II or just leave them on the Generation I cartridge?
Additionally, is it possible to replace the internal battery with some sort of glue or something rather than soldering it? I don't have a soldering gun or any experience soldering so currently I have no way to replace the batteries in my cartridges.
