v0.2.31 - Android S24 fixes + Windows build

Android

• Touch controls appear by default on a fresh install. The always-visible HIDE/SHOW button lets you toggle them during gameplay; existing control preferences are respected.
• Fixed the crash after choosing a ROM and tapping Start game on the Galaxy S24 Ultra by handling framebuffer compute pipelines rejected by its Vulkan driver. The game reached the title screen on the reported S24 Ultra.
• Fixed in-game audio crackling on the S24 Ultra. Audio driver selection now happens before SDL initializes audio; the device opened OpenSL ES at 48 kHz, and the tester confirmed the music sounds good.
• The ROM picker uses Android's document picker and copies the selected ROM into app-private storage. No broad storage permission or Android/data folder is needed.

The Android APK includes arm64-v8a and x86_64. It updates the previous release in place and preserves app data. No ROM is included; select your own legally dumped Castlevania: Legacy of Darkness (USA) ROM. On devices that reject the framebuffer compute pipelines, some framebuffer-based effects may render differently.

Windows x64

The Windows package is rebuilt from this release. Extract the ZIP and keep its DLLs and assets beside LodRecomp.exe. No ROM is included.

SHA-256 files are attached beside each download.

v0.2.30 - Android ROM picker fix + Windows build

Android ROM picker fix

• Select ROM in the launcher now opens Android's document picker. The chosen ROM is copied into app-private storage and validated before Start game becomes available.
• Cancelling the picker and failures while copying the ROM now show distinct launcher messages.
• The Controls screen clarifies that on-screen controls appear during gameplay, after the menu closes. The overlay is off by default and can be enabled under Settings → Controls.

No ROM is included. Pick your own legally dumped Castlevania: Legacy of Darkness (USA) ROM from Downloads or another document provider. There is no Android/data folder to fill and no broad storage permission to grant.

The Android APK contains arm64-v8a and x86_64. It has version code 230 and the same signing certificate as the published v0.2.28 APK, so it can update that release in place. The release build succeeded and the touch hit-testing suite passed 47 checks. Android 16 / One UI 8.5 still needs an on-device check.

Windows x64

Extract the Windows ZIP, keep its DLLs and assets beside LodRecomp.exe, and launch the app. The package contains no ROM. The Windows build completed and the packaged executable passed a five-second launch smoke test on Windows.

v0.2.28 - Android & Windows Issue Fixes

Castlevania: Legacy of Darkness Recomp — Release v0.2.28

This release includes stability, gameplay, and graphics fixes addressing issues reported on upstream for both Windows and Android.

Fixes & Enhancements

• Controller & Keyboard Menu Toggle (fliperama86#28): Added customizable binding support for opening and closing the config menu (recomp::GameInput::TOGGLE_MENU). Scanning for a new toggle button no longer erroneously cancels the prompt.
• Carrie Stage 4 Vampire Boss Battle Crash (fliperama86#29): Resolved access violation 0xC0000005 at 0x80960008 by expanding KSEG0 RDRAM mirror from 8MB to 256MB and adding a physical RDRAM guard range.
• Henry Scenario Transitions, Missing Objects & Input (fliperama86#27, fliperama86#31, fliperama86#33, fliperama86#35, fliperama86#36):
  • Fixed transition lock 0x20000000 in 0x801CABC8 with overlay Pair 129 tracking and a gameplay watchdog restoring object dispatch (crystals, NPCs like Edward, rock crusher floor) and pause menu controls.
  • Eliminated stuck full-screen black overlay in RT64 during gameplay transitions.
• Build Improvements:
  • Full native MSVC compilation support for Windows x64.
  • Optimized release APK with touch controls and audio for Android (arm64-v8a & x86_64).

v0.2.27 - Android port

First release with an Android port. Desktop behaviour is unchanged.

Android port (new)

Validated on a Retroid Pocket 6 (Snapdragon 8 Gen 2, Adreno 740, Android 13).
LodRecomp-v0.2.27-android-arm64-x86_64.apk contains arm64-v8a and x86_64.
Vulkan 1.1 is required. No ROM is bundled — the launcher asks you to pick your
own legally dumped Castlevania: Legacy of Darkness (USA) ROM on first run.

Fixes that made it playable

• Launcher crash after picking a ROM. The shared assets/ tree was never packaged
  into the APK (desktop gets it from the LodRecompAssets CMake target, which cannot
  apply to an APK), so lod_launcher.rml failed to load and the resulting null
  ElementDocument was dereferenced. Assets are now staged into the APK and unpacked
  to filesDir on launch.
• Crash on "Start game" (Adreno). RT64 sized the Vulkan descriptor pool to the
  requested variable descriptor count, while Adreno accounts it against the count
  declared in the set layout, so vkAllocateDescriptorSets returned
  VK_ERROR_OUT_OF_POOL_MEMORY and the failed allocation left a null handle that was
  dereferenced later. Shipped as patches/plume.patch.
• Broken, crackling in-game audio. Three separate defects:
  1. An off-by-2 in the resampler discard pointer - the length dropped 4 frames while
     the pointer advanced only 2, so every buffer replayed 2 frames and lost 2.
  2. SDL_AudioCVT is stateless, restarting the resampler phase at every buffer.
     Replaced with SDL_AudioStream; measured boundary discontinuities dropping from
     130x the background rate to 4x.
  3. The real cause: osAiGetLength() reported the whole SDL queue depth, while real
     AI hardware holds about two buffers. The game concluded its audio was covered,
     stopped generating, and re-submitted its current buffer - 54% of all submissions
     were byte-identical repeats. Capped to what hardware could hold: 0% duplicates,
     100.2% of realtime throughput.
• Null ElementDocument in create_context() now reports the offending path instead of
  crashing somewhere unrelated later.

Features

• On-screen touch controls (Settings -> Controls, off by default). Full N64 layout
  plus a MENU button, which is the only way to reach the emulator menu on a device
  with no keyboard or controller. Input is additive, so it works alongside a physical
  pad. Hit areas are aspect-corrected so they are circular rather than squashed.
• Cheats tab with six toggles: invincibility, money, red jewels, all consumables,
  max power-ups and Henry's ammunition. Applied every VI, persisted in cheats.json,
  with a launcher warning while any are active.
• Splash screens (landscape and portrait), launcher icon, and looping menu music that
  follows the in-app master volume and mute.

Build notes

• Requires JDK 17: AGP 8.5.1 will not run on Java 8, and this Gradle does not
  support newer JDKs.
• python tools/apply_submodule_patches.py applies the vendored patches/ to the
  submodules; the Gradle build runs it automatically. patches/plume.patch is
  required or the game crashes on "Start game" on Adreno. patches/rt64.patch also
  supplies file_to_c.py, which rt64's CMakeLists invokes but which is untracked
  upstream.
• Do not build with -Pandroid.injected.build.abi=...: it marks the APK
  android:testOnly=true, which cannot be sideloaded normally.
• A debug build is not playable - the recompiled functions compile at -O0, roughly a
  third of full speed. Always use assembleRelease.

Known limitations

• Signed with the Android debug key. Moving to a real key later forces users to
  uninstall, which deletes the ROM, saves and settings from app private storage.
• Only Invincibility is confirmed working in play; the other five cheats use
  verified-looking addresses but are unconfirmed. Writes are bounds-checked, so a wrong
  address is a no-op rather than a crash.
• Tested on one device and one GPU vendor (Adreno). Mali and PowerVR are untested; a
  failed Vulkan descriptor allocation now aborts with the driver limits printed rather
  than crashing obscurely.
• A release build cannot emit diagnostics: adb run-as is refused when the package is
  not debuggable and fprintf(stderr, ...) does not reach logcat.
• The portrait splash rarely appears, as MainActivity is locked to landscape.
