Cross-firmware reliability work. Testing pre-release — see what was and was
not verified at the bottom before installing.

NOT AN OFFICIAL MINECRAFT PRODUCT. NOT APPROVED BY OR ASSOCIATED WITH MOJANG
OR MICROSOFT. No game files are included — you supply your own legally owned
Bedrock APK.

New: Self test

The launcher menu has a Self test entry (or bash selftest.sh over SSH). It
checks firmware, panel, client, runtimes, audio, controls, storage and installed
versions without starting Minecraft or needing an APK, and prints a short
redacted report that is safe to paste into a bug report.

If the port does not work on your device, run this first — it will usually say
why, and it is the fastest way to get a fix.

If a launch freezes

Two things changed for the case where the game hangs and the handheld needs a
power cycle:

  • A startup watchdog supervises every launch. If the client stops making
    progress it writes logs/hang-report.txt, terminates it, and restores the
    frontend rather than leaving you stuck. It waits for a stall rather than
    enforcing a deadline, so a slow first launch on a cold SD card is not killed.
  • Every launch records the stage it reached in logs/stage.txt, overwritten in
    place so it survives pulling the power. After a freeze, the next launch reports
    where the previous one stopped.

Between them, a hang now leaves evidence instead of nothing.

If a launch fails to start

A failsafe ladder drops to a conservative launch profile (no CPU/GPU tuning,
no thread pinning, VSync on, 30 fps) and, if that also fails, to a minimal one
(X11 video, no Crusty context hand-off, sound off). Two clean launches climb back
to normal by themselves.

Anything above the normal profile is announced on screen with the reason and how
to overrule it. Pin it yourself with Safe mode in the menu. docs/FAILSAFES.md
lists every fallback and the evidence needed to remove it again.

Fixes

  • The game exits before the character menu when Wi-Fi is on. Old Bedrock
    builds crash if they think the network is up. The in-client guard only ever
    covered one arm64 binary, and the compatibility registry claimed it for three
    combinations where it cannot fire. The registry is corrected and the launcher
    now covers the gap. Network / LAN in the menu overrides it if you would
    rather keep LAN.
  • No sound on the 32-bit path. It selected no audio backend at all, so
    OpenAL tried PipeWire first and failed twice on images that ship the PipeWire
    libraries without a client config. Both launch paths now share one audio
    selection.
  • Wrong client chosen on mixed-architecture systems. ABI selection asked
    uname instead of whether the loader the client needs actually exists.
  • Menu input dead on some firmwares. The input helper was pointed at a
    process name that does not exist there.
  • Support bundles were deleting version numbers. Bedrock versions look like
    IP addresses, so the privacy filter had been rewriting 1.16.221.01 to
    REDACTED_IP — removing the most useful field from every bundle. Fixed, with
    addresses, emails and credentials still removed.

Also

The port now resolves which firmware it is on in one place instead of four
drifting copies; ROCKNIX and the ArkOS family have an identity for the first
time. The bug report template asks for the self test and how far the launch got.
docs/CFW-CONTRACTS.md records what each firmware requires and marks every
clause as measured or assumed.

What was verified, and what was not

Verified on reference hardware:

  • RG34XX-SP / Knulli and RG DS / ROCKNIX — launch and clean exit from the
    on-device menu with controller input, correct firmware/profile/panel/audio
    detection, watchdog disarming at the first frame, frontend restored with no
    leftover processes, and the failsafe ladder staying at the normal profile.

Not verified:

  • muOS and dArkOS/ArkOS have no reference device. Their support is derived
    from user reports and code, not measurement. The self test exists to change
    that — running it on those firmwares is the single most useful thing you can
    contribute.
  • Text entry, immediate relaunch, and a full controls re-check on both devices.
  • The RGDS LAN transition and companion-tab rows of the acceptance checklist
    were not re-run against this build.

TESTING.md carries the full per-firmware acceptance checklist and the current
state of every row.
