3DS Activity Log

Warning

The README below is WIP, might contain random notes.

This clearly lists the Playtime data is in the nand:/data/<ID0>/sysdata/00010022/

I was being dumb and searched in 0x00020202 0x00020212 0x00020222 Activity Log application savegame only to find pld.dat containing the app's save

Now I have the Pedometer.dat and PlayHistory.dat files

Parsing Pedometer.dat has been unsuccessful so far, PlayHistory.dat is a success

Thanks to TollyH https://gbatemp.net/threads/playhistory-dat-timestamp.580853/post-10297936

and https://gbatemp.net/threads/playhistory-dat-timestamp.580853/post-10085500 for the gm9 script

Steps to get your .dat files

Clone this repo
cd src && mkdir in (we will store the file from 3DS in here)
Get your 00000000 file (PTM savegame data) a. Copy the gm9 script (I bear no responsibility, ask smudge) and run it b. Or go to nand:/data/<ID0>/sysdata/00010022/ and copy the 00000000 file to your computer at src/in (in your cloned (this) repo)
cd .. (go back to root of the cloned repo)
git clone https://github.com/wwylele/3ds-save-tool.git at the root of the (cloned) repo (to extract contents out of 00000000)
mkdir src/data (will store extracted output here)
cd 3ds-save-tool
python disa-extract.py ../src/in/00000000 ../src/data/
See you have both the files in src/data (PlayHistory.dat and Pedometer.dat)

Convert PlayHistory.dat to PlayHistory.csv

cd src
python playhistory.py
See you have your data/playhistory.csv file
Open the web ui and upload this csv file!

Notes (to self)

probably have to let user select their timezone or identify since 3ds doesn't has any tz at all
3ds doesn't obey any tz, user just sets time, and AL writes timestamps based on that time, hence user's respective timezone (in which they would expect the time to be)
