The SBC and RG34XXSP ports hand LÖVE a source *directory*
(`love <dir>`), so `love.filesystem.isFused()` is false there and
`Boot.run` bailed on its first line. The launcher still offered
"Update vX.Y.Z" and "Restart to update", so an update downloaded,
verified, and then was silently ignored forever.
- Boot.canUpdateInPlace() replaces the fused-only gate: a packaged
build updates whether it is fused (AppImage, Flatpak game.love) or
unpacked, and only a dev / source checkout (engine "0.0.0-dev") is
excluded. Fails closed when the host cannot be established.
Prelaunch.updateAllowed now delegates to it, so the boot gate and the
`--update` gate cannot disagree.
- Check.hostPort() reads the release-target marker, with
POKEPORT_HANDHELD as a legacy fallback (the SBC launcher has always
exported it, so packs predating this change still identify
themselves). The marker was read from the environment but never
exported, so a full-package fallback on a handheld resolved to a
desktop AppImage that cannot run there.
- A handheld now fetches its own package ("Download port update",
reusing the worker's cross-platform download_full) instead of
offering a URL it has no browser to open, and reports "Update package
ready" once it is in the save directory for a manual re-extract.
- Launchers export POKEPORT_PORTMASTER / POKEPORT_RG34XXSP.
An in-place update only ever mounts a payload over the running source,
so relaxing the gate is less invasive than the fused path it joins.
A runtime bump still needs a full package, which the minShell gate
already reports as needs_full.
Tests: tests/engine/update_boot_host_gate.lua (new, 10 checks) pins the
gate; update_check_tests.lua pins both port asset names and hostPort().
scripts/test.sh --quick: all tiers passed; scripts/lint.sh: 0 errors.

Linux AppImage packaging
Releases ship raw AppImages (no zip wrapper):
gen1recomp-<version>-linux-x86_64.AppImagegen1recomp-<version>-linux-arm64.AppImage
chmod +x gen1recomp-*-linux-x86_64.AppImage
./gen1recomp-*-linux-x86_64.AppImage
Flatpak users should prefer the .flatpak bundle (see
linux-flatpak.md); it avoids host glibc / FUSE / curl
mismatches on immutable desktops.
Common failure modes
| Symptom | Cause | Fix |
|---|---|---|
Won't start / libfuse.so.2 |
No FUSE | sudo apt install libfuse2 (or libfuse2t64) or ./app.AppImage --appimage-extract-and-run |
| Update check / mods / save sync fail | Host curl missing or broken by AppImage LD_LIBRARY_PATH |
Install curl; current builds scrub LD_LIBRARY_PATH for host curl and keep it for a bundled AppDir curl |
| Settings / sync reset after quit | Portable mode next to a read-only AppImage parent (/opt, system dir) |
Remove portable.txt or move the AppImage to a writable folder; the game falls back to the XDG save dir when the probe write fails |
| "Download AppImage update" | Shell/minShell gate needs a full native package |
Download the new .AppImage, chmod +x, replace the old file. Handheld ports show Download port update and fetch their own package instead — see linux-arm-sbc.md |
| Steam / Game Mode weirdness after update | Overlay LD_PRELOAD / PID change |
HostShell unsets LD_PRELOAD for children and execvs $APPIMAGE on restart |
Network transport (HostShell)
Desktop Linux fetches go through host or bundled curl:
- Flatpak
/app/bin/curl(bundled, keep sandbox libs) $APPDIR/usr/bin/curlor$APPDIR/bin/curl(keep$APPDIRonLD_LIBRARY_PATH)- Host
curl(env -u LD_LIBRARY_PATH, and always-u LD_PRELOAD)
Portable mode
Drop portable.txt beside the .AppImage to keep saves next to the binary.
The launcher probes writability with a unique .write_probe_<time>_<rand>.tmp
file. Read-only parents fail soft and use love.filesystem XDG saves instead.
Flatpak ignores portable.txt.
Auto-update
In-place updates download gen1recomp-X.Y.Z.love into the save directory.
Full shell bumps open the matching AppImage (or Flatpak) download URL — there
is no silent in-place AppImage replace yet.
PortMaster-style ports (linux-arm-sbc, rg34xxsp) are unpacked Linux builds
too, so they apply the same .love payloads in place, but they have no browser
in which to open a download URL. On a handheld the full-package prompt fetches
the port's own zip into the save directory for the player to re-extract; the
port is identified by POKEPORT_PORTMASTER / POKEPORT_RG34XXSP. See
updater.md for the whole contract.
