kronos tags the ST-V BIOS epr-19854.ic8 taiwan, mednafen_stv tags it
asia-ntsc, the SMPC area Mednafen names for Taiwan (ss.cpp:1119,
2363-2364). As siblings under asia they never matched, so a request in
one spelling dropped the file tagged in the other, and --region
taiwan,us dropped the Saturn sega_101.bin. AREA_TERRITORIES relates
each area to the territory it serves, china for asia-pal included, in
region.py and its installer copy.
Names are matched on letters and digits, so the site's display names
work, and a typo gets the closest names instead of a full list. Hints
and advice give back the command the user ran (curl or PowerShell form,
every flag kept), --dest alone follows detection and says whose list it
installs, Ctrl+C at a question exits 130, and --cores-dir names a core
folder. install.ps1 runs in its own scope so irm | iex leaves the
session alone, and an override that causes a fingerprint mismatch is
named. --check lists hash mismatches first, missing required files are
grouped by system, and --help ends with examples.
On Windows the partial copy of a file of 16 MB or more is locked with msvcrt.locking, a LockFile region: the locking process cannot access that region through a second handle (Microsoft LockFile remarks). Hashing reopened the path, the read failed with a sharing violation, and every large file was reported as 'folder not writable' (issue 82). Both digests are now read in one pass through the handle that holds the lock. A read-only file already at the destination had the same misleading report: on Windows its attribute is now cleared before the verified copy replaces it, and a refusal that remains is named for what it is.
install.py --emulator NAME keeps what the named emulators read on the detected platform: their own files and the platform's files of the systems they run, as a pack built for them carries, without the systems no core is mapped to. Each emulator page now gives that command for Linux, macOS and Windows, beside the per-file links.
A copy refused by a read-only emulator folder raised the error count with no failures entry: the summary named no file, gave the BIOS folder as the location and no advice. The failure now carries its path, and the summary names the emulator folder and what to do.
--check counted the required files the list leaves out and named none, then said all files were up to date. A Recalbox user asking why Caesar III would not start learned nothing, though the list names c3.555. The count line no longer calls a file not found unsafe.
The live line divided every byte by the run's time, a partial copy left by an earlier run included, and showed a 3 GB resume as 2.5 GB/s with nothing left.
scoop install retroarch puts retroarch.exe under ~\scoop\apps\retroarch\current, its system folder persisted through a junction. The Windows search covered the installers' folders, Program Files, Steam, ES-DE and the Store package only, so the run offered C:\RetroArch-Win64\system, a folder that RetroArch never opens. The user and global Scoop roots are searched now, %SCOOP% and %SCOOP_GLOBAL% included.
--list-systems, --list-cores and --list-targets read the manifest and write nothing, yet with --platform bizhawk they went through the portable-install refusal and stopped asking for --dest. Someone checking BizHawk's firmware before downloading BizHawk got an error. A listing now runs whether the platform is installed or not.
A platform named but not found fell back to a folder it never opens: ~/bios for RetroBat on Linux and for BizHawk picked from the menu, and on Windows the embedded systems' /userdata/bios, which resolves to the root of the current drive. Each run downloaded gigabytes and reported done. Where no folder on the OS is one the platform reads, a forced run now asks for --dest and the menu asks for a path with no default.
Lakka's image writes the board in /etc/os-release: LIBREELEC_DEVICE when built for a device, LIBREELEC_PROJECT otherwise, the very names of our Lakka targets. The installer read the board on Batocera, Recalbox and ROCKNIX only, so a Lakka RPi4 installed 5.7 GB of every board's files where its own needs 4.0.
Opening and locking a partial download are two steps. Between them another run could finish, rename the same file into place and release its lock. The second run then locked the installed BIOS, read its full size as a finished partial and truncated it to download again. After the lock the partial's name must still point at the locked file, or the run downloads into a private copy.
RomM lists a platform's firmware folder without descending (base_handler.py:1002, recursive=False) and EmulatorJS writes the chosen file, or each zip member, under its bare name. 543 files of the RomM pack sat below a folder where no core could read them. The registry now marks RomM's folder flat, and such files are omitted with the reason below_platform_folder in the manifest and the installer.
Profiles, the wiki, comments, docstrings, command output and schema descriptions carried em-dashes, clause-joining semicolons, unicode arrows, box-drawing banners and check-mark glyphs. Each sentence was rewritten rather than having its character swapped. Hashes, paths, source_ref values and every cited file:line are unchanged, which a comparison of each parsed profile against the previous revision confirms.
validate_pr comments now say PASS and FAIL in words, and source_ref values in a profile's structured blocks render as code. test_prose_style fails if any of these comes back, in tracked files or in the generated site.
--check names each missing or corrupt file, a read-only folder is reported once, Ctrl+C before the downloads stops cleanly, stdout keeps its order in a log, and the local check shows its progress.
Windows rules ran under WSL with C:\ paths read as relative and no Windows variables, so nothing was found and a forced RetroBat install went to ~/bios inside the distribution.
BizHawk reads the Firmware folder next to EmuHawk wherever the archive was extracted. The installer looked in ~/.config/BizHawk/Firmware, which no build reads, and wrote there when nothing was found.
Manifests list each data directory's source archive and the hash of
every file; the installer rebuilds the tree from the archive and keeps
only the files whose hash matches.
The RetroArch list is folded for Windows and macOS. Its manifest
now carries the names a case-keeping directory also needs, and the
installer adds them after probing the BIOS directory.
argparse completed a prefix into the only flag starting with it:
slots.py --emulator read profiles from a directory named after the
emulator and reported nothing, and pipeline.py --all built every pack
variant. Every parser now refuses an abbreviation.
The installer looked for retroarch.exe in C:\RetroArch-Win64 and
Program Files\RetroArch only, so a RetroArch under Program Files\
RetroArch-Win64, in a Steam library on another drive, or in an
installed ES-DE's Emulators folder went undetected. All three are
searched; Steam libraries come from Steam's own library list.
install.py held a local it never read and, since the registry path
rules, a loop variable shadowing the platform module, so the py38
ruff gate the installer is held to failed. Both are fixed, and the
suite reads the two rules from the syntax tree since CI has no ruff.
