Sector0F
A sector on the player that stores various information.
Record structure
Field descriptions
Unknowns
Unknown, apparently constant, values: 0x073B 0x07BE 0x07C3 0x0D8E 0x0E49 0x0F8E
Filler1
Unknown, apparently constant. Filled with 0x0FF.
Unknown1
Unknown, apparently constant. Value 0x0AA00.
FirstFree
The FAT element number of the first free block.
LastBlock
The FAT element number of the last block. Total memory on the player =
(LastBlock + 1)*0x0210*64
A better way to calcuate the amount of memory is to iterate through the FAT
entries and see which have NextBlock != 0x0FFFF.
Unknown2
Unknown, apparently constant. Value 0x5555.
Unknown3
Unknown, apparently constant. Value 0.
FATSectorCount
The number of (512 byte) sectors holding the FAT table. This could also be the
starting sector number of the FAT table. Usually 0x10.
Filler2
Unknown, apparently constant. Filled with 0x55.
