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
Items are loaded sequentially into data determined by the order they are placed in the KERNEL.BIN file. They are stored using 9 bits for an index and 7 bits for quantity:
In Binary: XXXXXXXX QQQQQQQX
Where X is the index and Q is the quantity. There are 128 Items (including the blank ones) and 128 Weapons. These are indexes 0-255. The Armors and Accessories are then loaded sequentially (32 Armors then 32 Accessories) and indexed 256-319. If the index of the stored item is over 255 then the final bit there is 1. Quantity is limited to 99 (1100011 in binary).
Save Materia List
Materia is stored as an index followed by the amount of AP on that instance of Materia.
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).
