Tell us about yourself!
I know it's been months since you replied to that other user (just noticed a dead battery on my dusty old Sapphire cartridge) but when you say you can "let the game run until the timestamp catches up" do you mean to start a new game and let it run, then shut it off without saving? Otherwise I can't see how to figure out how it would catch up to the save timestamp. Not wanting to buy the extra hardware to manually fix this timestamp problem, but also not wanting to lose the save data I have. Let me know if you can, thanks!
