ff6a:doc:savefile [ff6hacking.com wiki]

This is an old revision of the document!

All the test have been made on a (U) save file (.sav). The first $1E00 bytes of the file are 3 blocks of $A00 bytes for the 3 save slots. They are mostly similar to SNES $1600-$1FFF: Save RAM.

A block of data was added to the GBA port. Item inventory and Esper data were moved here when compared to the SNES version. The size of the block is 1024 bytes including a two byte checksum and it repeats three times for the three save slots.

Offsets	Description

`$23FC-$23FD`	Static mark 0x47, 0x4D (Slot will appear as empty if not present.)
`$23FE-$23FF`	Data extension checksum (Sum 16 + 1 from $2000-$23FD)

Bestiary was included in the GBA version and this block has its data. The size of the block is 1024 bytes including a two byte checksum and it repeats three times for the three save slots. Two bytes are used per monster and the byte order is the same as the monster index order. For a monster to appear in the bestiary, it needs to be slain at least once in a victorious battle. The victory increments a slain counter which gets values from 0x0-7FFF. 0x8000 clears the new entry flag. Total space is 1022/2 = 511 slots of which 384 are for pages visible in the game browser, 39 for unlisted monsters and the rest 88 are assumed to be empty. The last two bytes hold the bestiary checksum.

Bestiary
`$2C00-$2F4C`	Monster list
`$2F4E-$2FFD`	Empty space
Checksum
`$2FFE-$2FFF`	Checksum (Sum16 + 1 from $2C00-$2FFD)

Example values:

`$2C00`	28	Monster Guard has been slain 40 times.
`$2C01`	80	New entry has been cleared.

A quicksave option was included in the GBA port and it enables the player to temporary save the game almost anywhere. Quicksave cannot directly be transferred to the other slots in-game, but contains the same data as the other slots plus some additions.

`$3800-41FF`	Quicksave Slot data
`$4200-45FF`	Quicksave Data extension
`$4600-49FF`	Quicksave Bestiary
`$4A00-5BFF`	Quicksave Slot specific data; Last two bytes being a checksum?
