To eliminate System::GetInstance usage. Archive type like SelfNCCH and SaveData changes the actual reference path for different client, so archive backend interface should accept client information from the service interface. Currently we only pass the program ID as the client information.
Format information is currently only implemented for the ExtSaveData, SharedExtSaveData and SaveData archives, the information is stored in a file alongside the root folder of the archive.
The savedata for each game is stored in /savedata/<ProgramID> for NCCH files. ELF files and 3DSX files use the folder 0 because they have no ID information
Got rid of the code duplication in File and Directory
Files that deal with the host machine's file system now live in DiskFile, similarly for directories and DiskDirectory and archives with DiskArchive.
FS_U: Use the correct error code when a file wasn't found
- Refactor FS::Archive internals to make Archive creation and lifetime
management clearer.
- Remove the "Archive as a File" hack.
- Implement 64-bit Archive handles.
This is in line with what the hardware itself does.
It does this by splitting the initial directory opening into Directory.Open(), which will return false if a stat fails.
Then, Archive::OpenDirectory will return nullptr, and archive.cpp will return an error code .
Before, it used to use whether the directory actually existed. As a result, .citra-emu/sdmc was never auto-created (something quite confusing to me until I read through the logs).
