Hello. I really admire your battery solution and it's something that I myself have given lots of thought. I was just wondering if you could hazard a guess at something a question I have.
Do you think the same method of battery replacement could be used for Ruby and Sapphire cartridges? I believe that GBA games run on a 3 volt CR1616T battery. I am going to assume that, similar to Gold and Silver batteries, Ruby and Sapphire's will die after a long amount of time. I heard that the average battery Gold and Silver battery life is something like 6 years before a replacement is needed, and I wonder if it's the same amount of time for Ruby or Sapphire. Any thought on the matter would be appreciated, because I would like to try and remedy the situation before my characters are lost. Thanks for your time, and the handy replacement article!

Always,
Mark L.
