Pkg/PFS support #101

Closed Fox2Code closed 2 years ago

Fox2Code commented 2 years ago

.pkg files are special, they contain an encrypted (but decryptable, see documentation) PFS file-system.

The PFS filesystem should contain eboot.bin at the root of it.

Unofficial documentation: https://psdevwiki.com/ps4/Package_Files https://psdevwiki.com/ps4/PFS

For full PSF implementation some additional steps are needed like getting the title id from an xml file. (Not inside PFS)

<titlepatch titleid="CUSAXXXXX"> <- this is header, but CUSA00001 seems to be a good fallback if unable to read xml.

/mnt/sandbox/pfsmnt/CUSAXXXXX-app0/ <- PFS should be "mounted" there.

For raw eboot.bin usage, just linking it to /mnt/sandbox/pfsmnt/CUSA00001-app0/eboot.bin should be good enough.

Note: The issue is only about running basic homebrews that don't encrypt their assets, not about running full games.

Thanks, PKG support is definitely needed, but not now. BTW, ff there's some usable code for this format, that will be more good. :)

To start, you could probably take a look at how to parse them by looking into open source library managers like https://github.com/pearlxcore/PS4-PKG-Tool
