August 21, 2025Aug 21 Localization Seems like Nihon Falcom made their own file format similar to .p3a archive format from YS X (international version). .pac file Sample.zip Edited August 21, 2025Aug 21 by Andree Changed text
August 21, 2025Aug 21 The file format itself isn't too terribly complex it seems? There's seemingly no compression for those files either (at least in the demo). I've written a basic file extractor, it's probably far from perfect though.pac_extract.py

I don't have demo, but data of the package in the OP is obviously compressed with LZ-like algo. Falcom usually used their own custom LZ fork afaik, though it's worth to try quickbms scanner on it Edit hmm no, it seems you are right. These jsons looks strange, they look compressed in the beginning but later there are clear repeating patterns which shouldn't be there if data was really compressed.
