This allows Steel Diver to boot further, some files are needed.
This is still not ready and needs a big cleanup, this will possibly be delayed until the way we handle archives is fixed (with factory classes instead of ahead-of-time creation of archives)
They will be stored in /extsavedata/SDMC and /extsavedata/NAND respectively.
Also redirect some APT_A functions to their APT_U equivalents.
Implemented the gamecoin.dat file in SharedExtSaveData in the PTM module.
Implemented formatting the savegame.
Retake a previous savegame if it exists instead of reporting them as not formatted every time a game is loaded.
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.
