X/Y Save files are comprised of 4 sections, the latter two storing the contents of the two savegames.
The game alternates between the two game saves similar to Generations 3 & 4.
Save files are 0x100000 (1MB). The area between sections is either FF or 00, for Cartridges and Digital saves respectively.

Pokémon Bank (application?) data
This region is written every time Pokemon Bank saves. It is a copy of first 0x20 bytes of Pokemon Bank savefile (turtle). Maybe this is used to store information of the last application used with the game, but currently no other application that interacts with XY savegame is known.
| Offset | Description |
|---|---|
| 0x00-0x04 | Pokemon Bank unique ID? (seems linked to nnid) |
| 0x05-0x08 | Unknown (0x00) |
| 0x09-0x0F | Unknown, only present in turtle file (0x00 on game's savegame) |
| 0x10-0x14 | Bank usage counter backup (previous counter) |
| 0x15-0x18 | Bank usage counter |
| 0x19-0x1F | Pokemon Bank signature? (always 48CA0A0002000000) |
