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.AppImage`
|
|
- `gen1recomp-<version>-linux-arm64.AppImage`
|
|
|
|
```sh
|
|
chmod +x gen1recomp-*-linux-x86_64.AppImage
|
|
./gen1recomp-*-linux-x86_64.AppImage
|
|
```
|
|
|
|
Flatpak users should prefer the `.flatpak` bundle (see
|
|
[linux-flatpak.md](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](linux-arm-sbc.md) |
|
|
| Steam / Game Mode weirdness after update | Overlay `LD_PRELOAD` / PID change | HostShell unsets `LD_PRELOAD` for children and `execv`s `$APPIMAGE` on restart |
|
|
|
|
## Network transport (HostShell)
|
|
|
|
Desktop Linux fetches go through host or bundled `curl`:
|
|
|
|
1. Flatpak `/app/bin/curl` (bundled, keep sandbox libs)
|
|
2. `$APPDIR/usr/bin/curl` or `$APPDIR/bin/curl` (keep `$APPDIR` on `LD_LIBRARY_PATH`)
|
|
3. 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](updater.md) for the whole contract.
|
|
|
|
## Building
|
|
|
|
```sh
|
|
# x86_64 (macOS or Linux host with squashfs-tools)
|
|
scripts/build.sh linux --version X.Y.Z
|
|
|
|
# arm64 (aarch64 host + docker/podman)
|
|
scripts/build_linux_arm64.sh --version X.Y.Z
|
|
```
|
|
|
|
See [linux-arm64-build.md](linux-arm64-build.md) for the arm64 builder.
