In this post I explain how to restart the Real Time Clock (RTC) in Pokémon Ruby, Sapphire and Emerald after you changed the battery in the cartridge.
I found the solution here and I will create a tutorial for everybody to follow and as a way to archive the method.
What you need
Hardware:
So once you have swapped out the battery in you Pokémon R/S/E your work is far from done. Since the real time clock was stuck now it would have to catch up to today from the day the original battery ran dry. This would take 10 years or so. There might be other methods to extract saves but this is the one I know.
Step 1: Save Extraction
Step 3: Injecting the save
I found the solution here and I will create a tutorial for everybody to follow and as a way to archive the method.

- Nintendo DS/DS Lite (for the GBA Slot)
- NDS Flash Card + SD card (R4, Supercard DSTwo, TTDS...etc.)
- USB or built in SD Card Reader (to transfer extracted saves to PC)
