Every system that runs from its SD card comes from card_setups(),
derived from the device rules: the setup list, its filter, --platform
and the line menus give each its own row and ask for its card. The
RetroArch row no longer lists handheld systems.
card_root_folder and card_choice share one identity check: another
system's card is refused for every system, KNULLI and ROCKNIX included,
and the same --dest gives the same folder from every entry point. WSL
drive letters are read as typed, the line question lists only that
system's cards and asks again after no.
Offline at a terminal, files left out count as missing: the run ends
with code 1 or 2, as the full screen does. Continue on the systems list
opens Confirm. Wording and layout points of code_audit_13 and
tui_audit_6.
The line mode under --offline, with files that need the internet,
ended on Done with 0 files installed. It now counts them as not
downloaded and says --offline is why, not an answer.
Back from the systems list with nothing ticked keeps the ticks it
opened with, and None says First system once nothing is left to untick.
Confirm under --offline with nothing on hand has no Install, and the line
mode no longer asks to download what --offline never fetches. The line
mode counts the data files before its question.
Screen words: the checking clock starts at zero, a pack installs from
the pack, the copies found are said on a line of their own, the screen
of misplaced files says the copies stay, the save folder gets a line of
its own, the shared note is one line, a size keeps its unit, the same
save folder remedy on both screens, A Tick on the Miyoo bar, no Home
key in the help of a pad, and a system name said once with a pack.
A card system chosen on a computer, from --platform, the setup list, its
filter or the line-mode menu, always asks for its card. The card screen
lists only the cards whose files say they run that system, offers Look
again, and checks a browsed, typed or --dest folder as --dest is checked.
The line-mode Card root prompt lists the mounted drives, asks again on a
missing or foreign root, and asks before creating several folders. On the
device the detected folder is offered, and the bound card is forgotten
when another setup is chosen.
A long systems list opens on None. A there unticks every system and
moves to the first one, and A on a system with nothing ticked installs
that one alone, so Enter still continues. Inside muxterm, which keeps
PgUp and PgDn for its scrollback, Left and Right on the D-pad page.
One system of 66 at 40x15 took 17 presses with a pad, 57 in muxterm;
it now takes 12 on both. The pyyaml check of the device lists skips
where pyyaml is not installed.
A system that runs from its SD card (Onion, spruceOS, muOS, KNULLI,
MinUI...) named with --platform on a computer no longer takes that
computer's RetroArch folder: one mounted card of that system is used,
at a terminal the card root is asked, without questions the run stops
on the --dest example. The interface opens the card screen with the
mounted cards first.
The result pager scrolls and counts lines, so its last line is
reachable at every size. The setup filter knows the devices each
setup runs on, from the guides and the firmware pages. A new event
kind, data, gives the bytes of the data trees, and the plan shows
them.
--add-app, the result screen and a [y/N] question put the launcher of
muOS, KNULLI or ROCKNIX on the card the BIOS folder is on. The files come
from install/launchers/index.json at the same ref, each checked by size
and SHA-256 before the first is written, and the app event reports it.
The Flatpak RetroArch's folder at 000 hid the retroarch.cfg naming ~/Games/bios, and the run offered 6.6 GB to ~/.config/retroarch/system. A closed folder under HOME or above the default now leaves no default: --dest is asked for. Python 3.14's quiet Path.exists() refusals are told from absence by os.stat, and an assumed folder reads as the one a frontend usually reads.
One closed folder under HOME (~/.config/EmuDeck at 000) made the whole
detection return nothing: a RetroArch whose retroarch.cfg was readable
was lost and the run fell back to a folder it does not read. Every
detection probe now goes through _exists, _is_dir or _is_file, which
count a refused place as absent, name the closed folder once, and let
the other probes go on. The decorator stays as the last net.
The refusal is an unsearched event before detect. The interface keeps
the line above the list of setups. At HOME or a drive root A goes into
a visible subfolder, never a card or drive row nor .cache, and with
none it stays on Use this folder and says where it is. A default folder
taken because the platform was not found is no longer called detected.
With no usual folder the browser opened at HOME on Use this folder, and A pressed through the screens installed the BIOS files into ~. At HOME or a drive's root A now opens the first folder. Picking the old card to copy from is unchanged.
HOME kept across su without - made every detection probe raise PermissionError, and the run and the interface ended on a traceback. Detection now finds nothing there, says which folder this user cannot open and how to go on, on the first screen too.
The handheld launcher compared the idle close's line without install.py's RetroBIOS: prefix, and its test fake printed it the same way, so the device still waited 300 s: a test now ties both to TUI_IDLE_WORDS. The interface offered the built-in default folder when the folder found here could not be opened, a folder RetroArch does not read.
A system_directory read from retroarch.cfg under a folder this user cannot open ended the run, and the interface before its first screen, on a traceback. It now gets the refusal --dest gets. On a handheld, an idle close on an error screen shows that error for a few seconds instead of waiting for a button that cannot come.
gptokeyb2 owns the pad in muxterm on muOS with PortMaster, and muxterm keeps PgUp and PgDn for its scrollback. The launcher now says so with RETROBIOS_PAD=gptokeyb_muxterm, and the hints name the gptokeyb buttons with no paging key.
A server that took the connection and never answered held line mode
93 s, three waits of 30 s for a first byte. A file list now waits 15 s
per answer and asks a silent server twice. Downloads keep their own
timeout between chunks.
With --offline and no list, the full screen said No connection and
offered a Try again that could never work. It now names offline mode
and the two ways a run gets its list without the network. With a list,
the plan counted downloads the run forbids: it says what this machine
can supply and what needs the internet, and the printed command keeps
--offline.
The size column took half the line and cut every name to eleven
letters: Game Boy, Game Boy Advance and Game Boy Color read alike. A
system row now carries shorter size forms, and the longest one that
leaves the name whole is shown, none when that is what keeps it.
RETROBIOS_IDLE_EXIT=SECONDS: with no key on the first screen for that
long, before any choice, the interface exits 0 with one line. A mapper
that never opens the pad no longer freezes a handheld there.
A damaged member of a data tree's archive (zlib.error, EOFError) ended
the run on a traceback, and a failed write left its .part. --offline
refusing a data tree, or the download after a --from copy failed, lost
its kind, so the advice named the network instead of --offline.
A run given --dest detected nothing, so retroarch.cfg was never read:
the full screen, which names every folder, sent Azahar's keys.txt to a
guessed RetroArch/saves or dropped it without a word, where line mode
wrote it to savefile_directory. The configs are now read once when a
save directory is asked for, and the plan and the result say what was
left out.
--dest NOTMUOS/bios ended with MUOS/bios as text and passed as a muOS
card's folder. A card two systems claim now says so in one line, and
the system named among them decides the folder.
The line output printed the --from folder, the files found there and
the BIOS folder paths as they are: a name holding ESC drove the
terminal. screen_text moves out of the interface section and cleans
every line of the check, the copy plan and the unreadable list.
Each ZIP member read reopened its archive and parsed its directory
again: 4000 members of one size made 4000 parses. A folder index keeps
the archives it reads open, 16 at most, read under a lock from the copy
threads, and every index is closed at the end of the run. Archives the
list installs are still opened and closed at once.
A folder or a file the user cannot read at a destination ended --check
and the install on a traceback from the hashing pool. --check now gives
the reason per file, and the install fails that file alone, before any
download for a folder.
--declared-only settled each slot on its first declaration before the
cores narrowed the list, and the declared event judged the core copy
served in its place. Both now read the declaration whose systems
remain, as the platform checks it.
An owner file holding a number past a pid raised OverflowError before
the screen opened, and a full temp disk stopped the run on the owner
write. 0 and negative numbers are unknown owners, not process groups.
A closed window under a changing screen failed the draw (EIO, or a
termios.error from the SIGCONT that comes with SIGHUP) before the
signal was read, and the run ended on 1 with a crash log kept.
The hint bar, the help and the install's stop line read RETROBIOS_PAD:
gptokeyb, evmapy, muxterm and miyoo each name their own buttons and
none they lack. A desktop names keys only, SteamOS game mode and any
unknown run keep both names. On a Miyoo, A (Space) chooses, L1 and R1
page, and R2 goes back: B is Left Ctrl, which sends no byte alone.
SIGTERM and SIGHUP are handled from the start of the run, so a stop
during detection ends on the farewell. A closed window now ends with
129: once the last write fails, stdout and stderr point at /dev/null
and the flush at exit no longer turns the code into 120.
--offline (or RETROBIOS_INSTALL_OFFLINE=1, which the runs the
full-screen interface starts inherit) makes no network request. The
file list stops the run at once with an error event of reason
offline unless --manifest or --from-pack gives it, a file the run
would download fails at once with its own advice, and board detection
is skipped. --target and --list-targets refuse it. RETROBIOS_OFFLINE
is not reused: CI and the test suite set it for every process, and the
installer tests serve their files over loopback.
A connection now has 4 s to open, then the read keeps its 30 or 60 s
timeout: three tries that never connect end in about 15 s instead of
93, and a slow but open transfer is not cut.
A --dry-run prints its totals first. A plan taller than the screen
names the ten largest systems, and --verbose lists every system and
file. Events are unchanged.
--declared-only keeps the entries the platform's own list declares
(cores: null), each slot settled to the platform's copy with no core
alternative left behind. Install, --check, --dry-run, --events,
--list-systems, --system, --region, --emulator, --target,
--installed-cores, --manifest and --from-pack apply it. --core,
--list-cores, --list-emulators, --list-platforms, --list-targets,
--standalone-copies, --restore and --tui refuse it, and the interface
does not open by itself with it. On Batocera it gives 353 files of
14531, the list batocera-systems checks.
Event decision: no schema bump. A `declared` key on `file` would add a
key to an existing kind, which schema 1 forbids. A new kind, `declared`,
follows `check` with the same counts over the platform's own files and
their dests in file-event order. Readers already skip a kind they do
not know (rbevents.py and the interface reader were checked), so
EVENT_SCHEMA stays 1.
An unknown --system is answered with the systems the list files its
key file under: --platform retroarch --system snk-neogeo now suggests
arcade, which holds neogeo.zip, instead of snk-neogeo-cd. neogeo, mvs
and aes follow the same route. Never taken, only suggested. A system
title the manifest carries (SNK Neo Geo CD) is taken for its id when
no other system shares it and no platform name reads the same.
schemas/install-events.schema.json is written from EVENT_KEYS by
scripts/generate_event_schema.py. validate_schemas.py reports a stale
file, and tests compare it with EVENT_KEYS and validate a real run.
Bootstrap pins recomputed.
The speed is bytes_network over time, the interface's own guess at local
bytes is gone. The plan says when a --from folder was read only in part
or holds another drive, and how many files on the old card could not be
read, with a list of each reason. The --from folders are only checked
before the screen opens, never indexed there.
- A handheld card mounted on a computer is found by the files its
firmware writes there: muOS, Onion, spruceOS, CrossMix, Allium and
Koriki from their device rules read below the card root, KNULLI and
ROCKNIX from the share their first boot seeds. It is a setup of its
own ("muOS SD card (E:\)") with the folder that system reads, and
--dest <card root> writes there too. --platform muos with a folder
that is no muOS card is refused with the folder to name.
- Space (X on PortMaster, Y on muxterm) opens the confirm screen from
Install and never installs, closes or quits by itself.
- Short of space, Choose another folder comes first, and the result
says the card is full in words, with no log lines and no command
naming the interface's own copy of the list.
- The plan keeps the BIOS folder second, cut in its middle, a --from
folder by its name, and the config that named the folder.
- The result says how many files came from the old card, how many
were downloaded and how many are still missing, as the line mode.
- The "other" row is named and explained, files shared by several
systems are counted apart, and a file that cannot be supplied is
named with its system, only where it matters.
- A work folder left by SIGKILL is removed by the next run, a failed
run's log after a week. A full card keeps no log.
- Smaller: the sudo advice names the folder, removing a --from folder
says so, the preview counts its files only, a proxy is named, a list
that is no JSON and the clock error read as plain sentences.
The engine counts the bytes a copy, the pack or a resumed partial copy
supplied, and those the network brought. A transfer event carries both
after each progress event and once when the downloads end, so a screen
shows a download speed without guessing.
The walk no longer enters another drive mounted below the folder (it is
named instead), /proc, /sys, /dev or a Windows junction, and the root of
the system is refused. from_folder_problem() checks a folder without
reading it. A scanned event reports each folder read, cut short or not.
A file, ZIP member or folder below a --from folder that could not be
read was taken as no match. When its size is that of a file the run
still needs, or unknown, --check, --dry-run and an install now name it
with the reason, and an unreadable event carries it.
A copy that could not be read when it was copied was reported as a
folder not writable. The source is now opened first and its errors are
its own, and a download failing after it names both reasons. A run
reading a pack falls back to the pack, never to the network.
