The 7th Saga/SRAM map

The following article is an SRAM map for The 7th Saga.

SRAM

There are 3 save slots of $500 bytes each, which are mirrored in a second set of 3 slots.

Default for $0002 - $10ff is 0xff. Default for $1100 - $1fff is $00. Unused areas generally follow this pattern.

Primary Structure

Address	Size	Description
$0000 - $0001	word	Checksum using 16-bit XOR
$0002 - $01ff	$1fe bytes	Unused
$0200 - $06ff	$500 bytes	Save Slot 1A
$0700 - $0bff	$500 bytes	Save Slot 2A
$0c00 - $10ff	$500 bytes	Save Slot 3A
$1100 - $15ff	$500 bytes	Save Slot 1B
$1600 - $1aff	$500 bytes	Save Slot 2B
$1b00 - $1fff	$500 bytes	Save Slot 3B

Save Slot Structure

Save Slot Structure, $500 bytes.

To do: flesh out missing values, verify existing values, fix address ranges, etc.

Offset	Length	Description
$005	byte	Number of times saved?
$021	byte	Players's Character Selection, 00=human(warrior), 01=dwarf, 02=elf, 03=alien, 04=tetujin, 05=human(mage), 06=demon [TODO: move these to Values page]
$022 - $023	word	Players's level
$024 - $025	word	Player's current HP
$026 - $027	word	Player's max HP
$028 - $029	word	Player's current MP
$02a - $02b	word	Player's max MP
$02c - $02d	word	Player's Power
$02e - $02f	word	Player's Magic
$030	byte	Player's Speed
$031	byte	Player's ?????
$032	byte	Player's weapon slot
$033	byte	Player's armor/clock/robe slot
$034	byte	Player's accessory/helmet/shield slot
$035 - $037	long	Player's XP plus 30
$038 - $03a	long	Player's Gold plus 27
$03b - $04f	$100 bytes	Unused (00)?
$050 - $07f	$30 bytes	Companion's data (identical to Player's data)
$082 - $17d	$7e bytes	Inventory slots, byte 1 = item type, byte 2 = quantity
$17e - $17f	word	Inventory ending, unknown purpose, 00 00
$180 - $27f	$100 bytes	Unused (00)?
$280 - $2fd	$7e bytes	Quest flags?
$2fe - $3fd	$15 bytes	Unused (00)?
