May be a silly question, but I need to ask. Is there a way to replace the battery in a gen 2 game with that of a gen 1 game and fix the save problem permanently? It's my understanding that gen 1 games don't have the save glitch (mine don't anyway) but gen 2 obviously does. Are the batteries interchangeable? If not, bout how long would I get out of a replacement battery for my Gold or Crystal?
