The ContentRegion has been entirely dissolved. Its fields were not particularly useful, as the content records were just a duplicate from the TMD, the file data itself, and then two integers that were assigned during construction and then literally never referenced.
Instead, the only copy of the content records now lives in the TMD, and the content is stored within the title directly since that was the only meaningful field. All the content related methods were moved from the ContentRegion struct over to the Title struct, since the content just lives there now.
This should hopefully make things much easier to deal with as you no longer need to worry about keeping two separate copies of the content records in sync.
This also might all change again in the future idk
The rustii CLI now offers setting decrypt/encrypt commands, as well as a WIP emunand install-title command. This command currently only supports installing single WADs and not a folder of WADs like WiiPy.
To make EmuNANDs happen, library modules for parsing and editing setting.txt, uid.sys, and content.map have been added and have feature parity with libWiiPy. The basics of the library EmuNAND module also exist, offering the code for title installation and not much else yet.
