* Sector Layout:
*
* Sectors 0 - 13: Save Slot 1
* Sectors 14 - 27: Save Slot 2
* Sectors 28 - 29: Hall of Fame
* Sectors 30 - 31: e-Reader battle tower data, maybe? (note: depreciated in Emerald US)
*
* There are two save slots for saving the player's game data. We alternate between
* them each time the game is saved, so that if the current save slot is corrupt,
* we can load the previous one. We also rotate the sectors in each save slot
* so that the same data is not always being written to the same sector. This
* might be done to reduce wear on the flash memory, but I'm not sure, since all
* 14 sectors get written anyway.
