MM JP VC save file manipulation - Documentation
--------------------------------------------------

The save data is stored in the  EEP_NZSJ  file.
The game ID is  000100014e41524a  - the folder in sd:\savegames\ must be
   named like that for SaveGame Manager GX to be able to install it.
All 3 save slots are twice in that file, probably as a backup copy.
Each save slot is 0x4000 bytes long (=16 kilobytes).
If you want to edit a save slot, you have to edit both the "real" one and the "copy".
--------------------------------------------------

Addresses of save slots (0x4000 bytes each):
Slot #1:	0x00000 to 0x03FFF
Slot #2:	0x04000 to 0x07FFF
Slot #3:	0x08000 to 0x0BFFF
Slot #1 copy:	0x10000 to 0x13FFF
Slot #2 copy:	0x14000 to 0x17FFF
Slot #3 copy:	0x18000 to 0x1BFFF

Address of filename (0x8 bytes):
Slot offset +	0x0002C to 0x00033

Addresses of Lottery, Spiderhouse, Bomber code, checksum (0x32 bytes total):
Slot offset +	0x01370 to 0x0138F

Address of settings (targetting, audio, ...):
		0x0C000 to 0x0C005
   (unsure on this one, didn't take a closer look)
--------------------------------------------------

Filename details:
The filename is 8 bytes. Each byte is 1 character of the file name.
The characters are stored in the same order as ingame, so 0x0002C is the first character.
HEX codes for characters are:
0 - 9:		00 to 09
A - Z:		AB to C4
a - z:		C5 to DE
Space:		DF
Dot:		EA
Hyphen:		E4
--------------------------------------------------

Lottery, Spiderhouse, Bomber code, checksum details:

The Lottery code is 9 bytes. Each byte is 1 digit of a Lottery number.
The Lottery digits are stored in the same order as ingame, so 0x01370 is the first digit on the first day.

The Spiderhouse code is 6 bytes. Each byte is 1 color of the code. The colors are 0123 = RBYG.
The Spiderhouse colors are stored in the same order as ingame, so 0x01379 is the first color to hit.

The Bomber code is 5 bytes. Each byte is 1 digit of the Bomber code.
The Bomber code digits are stored in the same order as ingame, so 0x0137F is the first digit of the code.

The checksum is 2 bytes. It is an unsigned short.
The checksum is the sum of all bytes prior to the checksum in the save slot.
--> This means it's the sum of all bytes from  0x00000 to 0x0138D.
--> For a completely new, untouched slot it is  77D0 + filename + codes (lottery, spider, bomber).

Example (save slot #1, fresh file):

‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾
The filename here is	"Link    ".	 (Hex: B6 CD D2 CF DF DF DF DF)
...
The Lottery codes are	"123, 123, 123". (Hex: 01 02 03 01 02 03 01 02 03)
The Spiderhouse code is "R B Y G Y G".	 (Hex: 00 01 02 03 02 03)
The Bomber code is	"5 4 3 2 1".	 (Hex: 05 04 03 02 01)
[The following part is static, don't change that: 00 35 FA 74 01 01 FA FB 8A AC]
The checksum is		"7E 9C"		 (77D0 + filename + the three codes).

That means you can switch around the Bomber code without modyfying the checksum!
The checksum can be easily calculated using the Windows calculator in scientific mode.

Don't forget that everything you change in save slot #1 also has to be changed in the COPY!
