This is a small project to analyze the pld.dat file stored inside the 3DS Activity Log save file. It outputs the parsed data as a CSV. Right now, it should recognize 3DS, DSi, and eShop titles. DS, homebrew, demos, and custom added titles are not recognized right now. If there's a list of CTR TitleIDs somewhere for them, please let me know.
Note I haven't actually tested this on 3DS systems other than my own, so please let me know if this doesn't work.
The 3dsreleases.xml is from 3dsdb.com. DSi.csv was scraped from here, System.csv was scraped from here. I believe eShop.csv was scraped from here, but I'm not completely sure since I made this project around 6 months before publishing it on GitHub.
