The Savemap

The following is the general save format for the game. This data excludes the header data that differs between the PSX and PC version.

Note: For the preview descriptions below, changing these values does not change any in-game values. These are only used so a player can preview the data within the save file when viewing the Save menu.

Save Item List

Each item in the item list is stored as a word value with the quantity, expressed as a 7-bit value, concatenated with the item's index, expressed as a 9-bit value between the range of 0-320. 

In Binary:
QQQQQQQXXXXXXXXX
Where X is the index and Q is the quantity.

There are a total of 320 item slots in the save map and a total of 320 objects that are stored there, some of which are dummy items. The objects are indexed like this:
Indexes 0 - 127: Items
Indexes 128 - 255: Weapons
Indexes 256 - 287: Armors
Indexes 288 - 319: Accessories
Quantity is limited (by the menu mechanics) to 99 since there are only two characters available in the item menu to show quantity. A Graphical "glitch" occurs in the ten's digit when quantity exceeds that number. The menu only checks the current quantity to determine if the value can increase. The quantity will not decrease unless an item is used or sold so forcing the quantity to exceed this number will have no negative effects.

Save Materia List

Materia is stored as a single-byte index followed by the amount of AP on that instance of Materia stored as an unsigned 24-bit integer.

KERNEL.BIN Section 4 Entry

During game initialization, section 4 from KERNEL.BIN is decompressed and copied into RAM. This is all the initial values and structure for most of the Save, excluding the header data and the tail of the last bank (0x0054 to 0x0FE7).
