DarkSouls Save File Parser

DSFP means Darksouls Save File Parser.
Dark Souls is game of Namco Bandai with pretty hard to get it finished without being killed. Lot's of death, fun and broken gamepads/keyboards.

DSFP serves for getting/fetching your saved characters statistics purposes.

local

Works with:

Dark Souls: Prepare to Die Edition

Note, Dark Souls: Remastered could be supported as well, however its data is encrypted or obfuscated by some algo, it makes reading with templates and dsfp itself mearly possible. (So basically only unencrypted data are read properly).

!!!Note!!! that this repository has pretty much data about internal save file infrastructure and its design. Thouhg everything stored inside 010 editor templates. If you need to process through dark souls save file and make it dynamicly you'd probably need to build your own library based on discovered knowledge. Don't rely that python library someday could even appear ;)

Original source

Original source and some key knowledge were taken from this gist.

Common features

Supports fetching data about character's death, his/her general stats, hp and stamina. Whole bunch of reversed stats you can see in datasheet document which is placed here

(Help for reverse engineering DarkSouls save file is appreciated).

Binary Templates

Since May 02 2015 I use binary templates for further save format investigations and to make reverse engineering work much easier. Common documentation that have been written in 2014 has some wrong information about different places. Use 010editor to process Dark Souls save file with given templates.

Works proper with 6.0.x versions, (5.0 on current master branch could have some flaws in file read process)

Installation

For general installation you would probably need virtual environment with pip installed:

Python 2.7

user@localhost$ virtualenv --no-site-packages venv
user@localhost$ source venv/bin/activate
user@localhost$ pip install -r requirements/base.txt

optional

user@localhost$ pip install -r requirements/docs.txt

Python 3.x

document build requirements stored in py3.txt

Dependencies

python 2.7
python 3.3
python 3.4

Tests

Simply run python setup.py test or You could run tests via python -m unittest module or via run_tests.sh script

user@localhost$ ./run_tests.sh tests.TestDSFPReader

Fast Usage

You can parse Dark Souls save files and get data in standard python dictionary format

>>> import dsfp
>>> ds = dsfp.DSSaveFileParser('saves/DRAKS0005.sl2')
>>> data = ds.get_stats()
>>> data
[{
    'attunement': 8, 'body': 0, 'class': 0, 'color': 0, 'deaths': 0,
    'dexterity': 13, 'earned': 60, 'endurance': 12, 'face': 0, 'faith': 9,
    'gift': 0, 'hairs': 0, 'hp': 594, 'hp2': 594, 'hp_current': 594,
    'humanity': 0, 'intelligence': 9, 'level': 4,
    'male': False,  # False means female
    'name': u'TEST_2', 'resistance': 11, 'souls': 60, 'stamina': 95,
    'stamina2': 95, 'stamina3': 95, 'strength': 13,
    'time': 62, # in seconds
    'vitality': 11
   }]

Datasheets

There's no many information about Dark Souls save file format (as well as the other games), so there's not much complete around its format. Some knowledge represented here.

Please notify me here or by email (tarvitz [at] blacklibrary.ru) if you have something interesting around whole file format.

Documentation

Whole bunch of the docs you can read by clicking this link dsfp.readthedocs.org

Development

Note

Huge buch of data now represented in datasheets are still not covered in dsfp "api" just cause whole file-format and its datasheet is the main priority. You can use it for build your own parser or just read some non-random data from *.sl2 files. Though dsfp is not complete as it should, please search/read information in the docs mentioned above.

Roadmap

!!!Note!!! there's no commitment that I'll do it someday. Just a simple plan if I get back to darksouls file format for any reason.

I have no certain roadmap for this project and I inspect the data whenever I want to do it. In general these moments could be very short/long from time to time. So don't expect me finishing this work to some certain moment or something clear enough.

Use ./scripts/watcher.py and the other scripts (or may be another methods) to inspect data you need, contact me if you want to share them and have fun ;).

Watching

Use scripts/spy.py for watching some blocks of data (could be slow for present moment)

(ve)tarvitz@mebook dsfp $ python ./scripts/spy.py -f remote/draks0005.sl2 -w json/watch.json
