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.
An idle close exited 0 on every screen, an error one too. It now exits with the error's or the result's code and prints that screen's words after the idle line.
Path.exists() raised PermissionError from _missing_dest in line mode and from _choose in the interface. The run now names the folder and exits 1 (error event stage dest), and the interface asks for another folder.
The plan and the result now say how many files go to the save folder and
where, from a new saves event. With --from-pack they say the files come
from the pack, not a download. A stop asked for (Start+Select, SIGHUP)
ends on the plain outcome, without the log's last lines.
install.py > log.txt at a terminal wrote the menu into the file and
waited for an answer nobody saw. A question now needs stdin and stdout on
a terminal, otherwise the run goes on as with --no-input and says so.
A run given --dest, as every interface run is, never read the config
naming libretro_directory, so only installed cores found none where line
mode found them. core_dirs now asks _retroarch_config_for, as the save
directory does, and the advice to drop --dest goes.
RETROBIOS_IDLE_EXIT only counted while the first screen was up. Given
--platform, the check runs and the plan follows without a key, so the
close never came. It now counts from the end of the last run, as long as
no key has been pressed.
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.
The interface finds a muOS, Onion, spruceOS, MinUI, KNULLI or ROCKNIX card by itself (card_platform and the card rules in install.py) and lists it as a setup. The FAQ says so where it fills an SD card, within its word ceiling.
muxterm was allowed vendor and product 0001:0001, the id gpio-keys
gives the H700 pad on muOS before 2026-08-28: muxterm and gptokeyb2
both read it and every button acted twice. The allow-list is now
0000:0001, which SDL never reads back for a device (a vendor of 0 makes
a name GUID, read back as 0:0), so a pad plugged in later stays hidden.
- muxterm keeps PgUp and PgDn for its scrollback: in muxterm L1 and R1
send nothing, and the README and wiki stop promising paging there.
- The offline detection runs with RETROBIOS_INSTALL_OFFLINE=1 instead
of a closed loopback URL.
- Every launcher sets RETROBIOS_IDLE_EXIT=300 for the interface.
- ROCKNIX: control.ini's -sudokill goes through a sudo stub that runs
nothing, so the mapper starts with -1.
- The sentinel ends with its launcher, a closed terminal app writes its
status, a mapper lost mid-run is said and named (gptokeyb2 included),
and the unwritable-card message stays in view.
- Tests: an SDL GUID model, a gptokeyb2 that outlives its kill, an
interface that ignores SIGTERM, a zombie, a SIGHUP to the inner run,
arrow bytes at the question, ROCKNIX's sudo.
The exit status names 129 for a closed window and the --offline
refusals of --target and --list-targets, and the events say a crash
leaves no end line. RETROBIOS_PAD and RETROBIOS_IDLE_EXIT join the
environment table, muxterm's missing paging and the save directory
found under --dest are said, and the options at a glance list
--declared-only and --offline. The first install page no longer
promises a controller on a computer, and gives the RetroPie command
for Windows too.
The FAQ said to unzip a pack before --from-pack, which reads the ZIP, its parts or their folder as they are. A lost or wiped card now has its answer, --from, linked to Copy from an old card. Can I play without the BIOS goes, Do I need BIOS files answers it.
The glance on the installer page is written from install.py's argument parser when the page is built, grouped by GLANCE_GROUPS. An option no group names lands under Other, so a new option cannot be left off the page.
terms weighs 20, so the version table outranks MAME parts. The FAQ carries ios, iphone, ipad, the file page check my dump, and a console's regional lead names it (the PlayStation BIOS). The FAQ quotes the bootstrap's fingerprint message again. The troubleshooting page, which answers the dc/ trap, joins the pages that answer dc bios missing. The gate starts node without its compile cache.
Root pages nothing produced are swept, so a table moved to a platform page no longer keeps the address its redirect needs. Data tree pages name their readers, board crumbs end on the Arcade page once, fba2012 is headed FB Alpha 2012, test profiles get no page, and the installer glance lists --declared-only and --offline. sitesources.py goes through run_cli.
check_freshness reports source-paths.json STALE when it records a tree no profile pins any more, and tools.md names sitesources.py --fetch where pins move.
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.
Every launcher exports RETROBIOS_PAD: gptokeyb, muxterm, evmapy or
miyoo, so the interface can name the buttons that reach it. The wiki
lists the values, and the tests check each launcher's.
Apps such as AetherSX2 named their user data folder only in prose, so
the site could neither print it nor show only the OS tabs that apply.
data_root keys android, ios, windows, macos and linux, each with the
path the user finds and the source_ref that builds it.
Release packs now exist for six platforms only, and install.py refuses a
pack named for another. build_port.py writes packs.txt from the
registry's release_pack groups. Offline, the launcher takes only a pack
spelling the detected system, names that pack, or says no release pack
serves it and gives Wi-Fi or the computer route.
