Updating instructions:

1. On your old version, SAVE INSIDE OF the Olivine PokeCenter, then close the game.
2. Press F1 to continue
3. Replace your old .gbc file with the new .gbc file
* Don't forget to make sure your .gbc and .sav file are named the same thing!
4. After entering the overworld, walk down and exit the Olivine PokeCenter.
5. Once you're outside, press A on the "POKE" sign on the building.
* If the game needed to fix anything in your save, you'll be warped inside the building. Your save is now updated, so go ahead and save the game.
* Otherwise if you hear a "ding" sound, everything's fine and you can continue your adventure.
6. You're done!
