Without Python, install.ps1 at a console now offers to run winget install Python.Python.3.12, rereads PATH from the registry and carries on. The Store's python.exe placeholder fails the version check like a missing Python.
Without Python the bootstrap told every system to run sudo apt install python3. It now reads Termux, macOS and /etc/os-release to name pkg, xcode-select, apt, dnf, pacman, zypper or apk, and in Termux offers to run pkg install python, which needs no root.
With no platform detected, a machine running standalone emulators (ES-DE with DuckStation and PCSX2) was offered RetroArch's folder. The installer now fills the emulator folders of the standalone copies list that exist here, from the EmuDeck then RetroArch file lists, asking first at a terminal.
Every install ended on 'Standalone copies skipped', on machines with no standalone emulator as on one whose DuckStation lacked its BIOS. The line now lists the emulator folders that exist here, and nothing is said when there are none.
A mistyped --dest was created with every missing parent and reported done. The run now names the missing folder and the nearest one that exists, asks at a terminal before creating more than one level, and prints the folder it created. The free-space check now runs before the folder is made and ends with 2, nothing installed.
--list-systems, --list-cores, --list-emulators and --list-targets with nothing detected were answered with an install command that dropped the listing and added --dest. The hint now names the platform and keeps the listing.
EROFS was advised like a permission refusal, and sudo fails the same way on a read-only mount. The advice now reads the mount flag and says to check and remount the card or drive.
BusyBox wget has no --https-only and refused the whole command, so a curl-less Alpine system (the RomM image) could never bootstrap. The flag is passed only when wget lists it.
EmuDeck's macOS build reads ~/.config/EmuDeck/settings.sh like the Linux one (functions/all.sh:3-4,24 and vars.sh:2 at dddb3022). The settings and ~/Emulation/bios rules now run on darwin too.
RomM 5.4 reads each platform's firmware where filesystem.structure.firmware
in config.yml says, bios/{platform} by default, and suggests {platform}/bios
for a {platform}/roms library (rommapp/romm 5.4.0,
backend/config/config_manager.py:58,101-109,205-225,564-568,1105-1124).
The installer only wrote bios/<platform>/. It now reads the template from
config.yml beside the library, takes --romm-firmware when that file is
elsewhere, refuses a platform-first library with no template, and detects
RomM by /romm/config/config.yml too.
No Batocera build writes /etc/batocera-version: batocera-system.mk:21-22
(batocera.linux 38845725, unchanged since batocera-30) writes
/usr/share/batocera/batocera.version. Knulli (knulli-linux 57afa662) adds
OS_NAME=knulli to os-release, writes /usr/share/knulli/knulli.version and
removes /usr/share/batocera, and no Knulli source writes /etc/knulli-release.
Neither was detected. A Knulli board is named and not narrowed by
Batocera's per-board lists, and an unlisted board is named.
muOS runs RetroArch on a config copied from its default, which reads
/run/muos/storage/bios, bound to MUOS/bios on the second card when that
card holds one, and loads cores from /opt/muos/share/core (MustardOS/internal
f41f4a89, script/control/retroarch.sh:8-20, script/device/bind.sh:116-150,
retroarch.default.cfg:2806,3151). The installer wrote to /mnt/mmc/MUOS/bios
and --installed-cores found no core. The config now decides both.
functions/all.ps1:4-14 (emudeck-we 037460ef) reads the APPDATA
settings.ps1, else the one under the profile, and takes C:\Emulation when
neither names a folder. Only the first was read and a forced platform fell
back to %USERPROFILE%\Emulation\bios. A network install names its share
through $VolName (JSONtoPS1.ps1:166-172), and a UTF-16 settings file is
decoded.
RetroBat.exe writes its folder to HKCU\SOFTWARE\RetroBat
LatestKnownInstallPath on every start (retrobat-executable 702da66a,
Program.cs:57 and 99, RegistryTools.cs:15-50). Only C:\RetroBat and the
profile folder were looked at, so an install on D: was missed and a forced
--platform retrobat wrote into C:\RetroBat\bios. The value is read
through winreg, or reg.exe under WSL, before the fixed folders.
A run whose downloads were all cut ended on "Location that was being
written to" and "once that is resolved", pointing at the disk. A
failure caused by the connection (lookup, reset, timeout, TLS, a cut
transfer, HTTP 5xx or 429) is now marked as such, and the summary says to
check the connection and HTTPS_PROXY.
An unknown --emulator name pointed at --list-cores and counted 441 names
while --list-cores prints 189: the buildbot names --emulator accepts
(mednafen_psx for beetle_psx) were listed nowhere. --list-emulators prints
each accepted name beside the emulator it stands for, and the hint names
it.
A [Parameter()] attribute made install.ps1 an advanced script: its common
parameters took -v (-Verbose), -vb, -d and -ea before install.py saw them,
and the scriptblock form printed PowerShell's own VERBOSE lines. The
wrapper now forwards $args as typed.
A link already at the destination was skipped without a word and counted
as "dir not found" while the folder existed, so the emulator kept the file
the link pointed at. The link now gives way to the file, written beside it
and renamed over the name, and a name leading out of the folder is a named
failure.
On Windows a verified partial copy is closed before its rename. A second
run that claimed it in that moment truncated it and the first rename failed
with a sharing violation, reported as an unwritable folder. A complete
partial is now left whole there, the rename waits for a sharing violation
to clear, and a sharing violation no longer reads as a refused folder.
The check walked the published keys only and skipped null lists: a
target the builder knows and the installer lacks, or a null left behind
once the builder filters it, passed. It now compares both key sets and
every value, null included.
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.
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.
BizHawk's NDS firmware slot accepts six dumps, two of which the collection holds, and the profile named one. Kega Fusion's US Mega CD BIOS covers the Americas. Sonic 3 A.I.R. data is installed by Batocera in unpacked form. izApple2 downloads its ProDOS images when a card is added, which is no install. The Lakka list now equals a case-keeping RetroArch install less what Lakka's packages install, and the profile hash contradiction count leaves out entries no pack ships. The pipeline table names step 8b.
A copy filed under two consoles of one maker was listed twice with the same id, and a data directory listed the same bytes twice, so the site deploy refused 20 pages. The first card keeps the id. The pipeline only generated the pages, so it now renders them with mkdocs build --strict and runs validate_site as the deploy does. The resumed-speed test read the clock and failed on a slow runner, it now fixes the elapsed time.
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.
--standalone-copies named Linux and Windows folders for Azahar's aes_keys.txt and boot9.bin and Flycast's dc_boot.bin and dc_nvmem.bin, and nothing for macOS, where both emulators read a fixed folder: ~/Library/Application Support/Azahar/sysdata (common_paths.h:36,61) and ~/Library/Application Support/Flycast/data (osx-main.mm:83-101). A test now requires a macOS folder on every copy.
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.
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.
