And I don't need anyone to tell me so, thank you very much. * PoC: remove gc_dumper and nsp_dumper PoC; create nxdt_rw_poc with all gc_dumper and nsp_dumper capabilities + standalone ticket dumping + raw NCA dumping; use ftruncate() to set output file sizes whenever possible. PoC code is a mess, as always. Expect the features from the rest of the PoCs to be implemented into nxdt_rw_poc soon. * workflow: temporarily disable borealis build generation; comment out manual installation of up-to-date packages from Leseratte's mirrors because the latest devkitA64 Docker image has them all. * borealis: update to fix building issues with latest devkitA64. * bfttf: error out on invalid NCA signatures. * config: save configuration to the current working directory; parse and validate new "gamecard/write_raw_hfs_partition" flag. * defines: remove CONFIG_PATH macro; rename CONFIG_FILE_NAME. * gamecard: rename fs_ctx -> hfs_ctx everywhere; use HFS function calls to retrieve partition names. * hfs: move GameCardHashFileSystemPartitionType enum from gamecard.h and rename it to HashFileSystemPartitionType; add hfsIsValidContext(); add hfsGetPartitionNameString(). * nca/npdm: update comments to reflect latest HOS version. * nxdt_bfsar: always generate absolute SD card paths with the device name; error out on an invalid NCA signature. * nxdt_includes: include dirent.h; refactor Version struct to make it a union of all known *Version structs. * nxdt_log: don't write session separator if the logfile is empty. * nxdt_utils: log appletIsGamePlayRecordingSupported() errors; add utilsDeleteDirectoryRecursively(). * rsa: provide clearer function descriptions in header file. * services: handle usb:ds initialization. * tik: update tikConvertPersonalizedTicketToCommonTicket() to allow NULL input pointers as raw certificate chain arguments (much needed for standalone ticket dumping). * title: add titleGetApplicationIdByMetaKey(). * usb: refactor interface (de)initialization code; slightly improve ABI usage (console-side only); redefine ABI version field in StartSession command blocks; upgrade ABI to v1.1. * FatFs: rename DIR -> FDIR to avoid conflicts with definitions from stdlib's dirent.h. * gamecard_tab: display package ID from the inserted gamecard; fix displayed version numbers from bundled system updates below 3.0.0. * todo: add notes about creating devoptab devices for HFS/PFS/RomFS file tree dumping.
