Unleashed Recompiled for Android

Play the Xbox 360 version of Sonic Unleashed natively on a supported Android device.

This is an unofficial Android port of Unleashed Recompiled. It runs the game through static recompilation rather than emulating an Xbox 360, and includes an Android app, touch controls, gamepad support, a mod manager, and a custom Vulkan driver for many Qualcomm Adreno GPUs.

[!IMPORTANT] This project does not include the game. You must supply files from your own legally acquired copy of Sonic Unleashed for Xbox 360.

[!WARNING] This is still an experimental community port. Performance and stability vary by phone, Android version, and GPU driver. Keep a copy of your saves and game files.

What works

• The full game, including title screens and regular gameplay
• ARM64 Android devices
• Installing the game and mods from a .zip or folder directly in the app — no PC needed
• Staging Xbox 360 base-game, title-update and DLC package files for verified installation on first launch
• On-screen touch controls with multi-touch, touch camera control, and a drag-to-arrange layout editor; the layout adapts to the game (D-pad in menus, a SKIP button in cutscenes)
• Bluetooth and USB controllers
• Sound through speakers, wired headphones, and Bluetooth devices
• HMM and UMM-style mods through the included manager, including per-mod ConfigSchemaFile settings
• Signed in-app updates from this repository's GitHub releases
• Built-in Turnip driver plus importing another driver as a plain .so or an AdrenoTools/ExynosTools package .zip
• Game-file access through Android's system Files app
• App UI in English, Russian, Japanese, German, French, Spanish, Italian, and Portuguese
• Logs and hang diagnostics that can be shared without adb

The main development targets are Adreno 710, 725, 732, and 750. Adreno 720 and 722 are included in the bundled driver but need more testing. Other Adreno 6xx/7xx devices may work, but are not guaranteed.

Mali support is experimental. Recent Mali GPUs (Valhall generation and newer with a Vulkan 1.3 driver — e.g. G610/G615/G710/G715/G720) run the game through the stock system driver: the app detects a non-Adreno GPU automatically and skips the bundled Adreno driver. Textures are decompressed on the CPU when the driver lacks BC format support, which increases memory usage. Confirmed working on a Dimensity 8300 Ultra (Mali-G615). Older Mali generations (Bifrost and earlier) cannot work.

PowerVR and Samsung Xclipse are untested. On Xclipse devices the system driver is used by default; community compatibility packages from ExynosTools can be dropped into driver_import/ as a .zip to use them instead. If such a GPU supports BC texture formats natively, the launcher's Debug section has an experimental Force native BC textures toggle that skips the CPU-side ETC2 transcode (issue #72); leave it off on Adreno/Turnip, which genuinely lacks BC.

Before you install

You need:

• A 64-bit Android device
• Android 9 or newer
• A supported Qualcomm Adreno GPU (or a recent Mali GPU — experimental)
• Several gigabytes of free storage
• Your own Xbox 360 game dump

For the smoothest first run, start with the default graphics settings. The Android build defaults to a 50% resolution scale, no anti-aliasing, 4× anisotropic filtering, and motion blur disabled.

Installation

1. Download the latest APK from the repository's Releases page.
2. Allow your browser or file manager to install apps from unknown sources when Android asks.
3. Install and open UnleashedRecomp. The first launch creates the app's folders and prepares the bundled graphics driver.
4. Tap Install game files (.zip / folder) in the launcher and pick your game dump — either a ZIP archive or an extracted folder. The app finds the game inside the archive automatically, however the folders are nested, and copies everything into place with a progress display. You can also choose ISO / update / DLC packages, select the base game, title update and optional DLC files together, then launch once to verify and install them.
5. Tap Launch game.

A raw dump (game + update, with optional dlc) is enough: if the patched folder produced by the desktop installer is missing, the app builds the patched executable itself on first launch. No PC is required at any point.

• Open Android's Files app, choose Unleashed Recomp game files, and copy the game, update, and optional dlc folders from your dump into the folder shown by the app.
• If your file manager cannot see Android/data, put the same folders into Android/media/com.sega.sonicunr/UnleashedRecomp/ instead — that folder is browsable by regular file managers and the app picks it up automatically. Driver packages can likewise go into Android/media/com.sega.sonicunr/driver_import/.
• Do not use adb push directly into Android/data. Files created there by the shell can receive ownership that prevents the app from reading them.

Controls

The touch controller appears automatically when you touch the screen. It provides:

• Left analog stick — which turns into an 8-way D-pad while a menu, the title screen, or the world map is open
• A, B, X, and Y
• LB and RB
• LT and RT
• Start and Back
• Camera control: drag anywhere on the free right half of the screen (default), or switch to a dedicated virtual right stick in the launcher's Controls card

During in-engine cutscenes the controls collapse into a single SKIP button; the full layout returns when gameplay resumes.

Every control can be repositioned and resized: tap Arrange touch controls in the launcher to open the drag-to-arrange editor.

The layout adapts to context: the left stick becomes a directional pad in menus, on the world map, and on the results and level-up screens, and everything collapses to a single SKIP button during cutscenes and the attract movie.

On-screen control settings live in the game's own options menu under Input:

• On-screen controls — when the touch overlay is shown (Auto, Always on, Off).
• Touch camera — swipe on the right side of the screen, a dedicated right stick, or off.
• On-screen stick — a virtual analog stick, or an 8-way D-pad you can also use during gameplay (issue #68).

The Video category adds Show FPS and Show Profiler toggles. To drag the on-screen buttons into a custom arrangement, use Arrange touch controls in the launcher.

When a physical controller sends input, the touch overlay hides itself. Touch the screen again to bring it back.

USB and Bluetooth controllers supported by SDL should work without additional setup. In-game prompts may not match every third-party controller exactly.

Installing mods

1. Tap Install a mod (.zip / folder) in the launcher's Mods card and pick the mod archive or folder. Every mod inside is detected by its mod.ini — archives containing several mods install in one go.
2. Tap Manage mods, enable the mods you want, and arrange their priority. Mods that declare HMM's ConfigSchemaFile show a settings button for their own booleans, numbers, text values and lists.
3. Tap Save mod list and restart the game.

Mods can also be copied into the mods folder manually through Android Files (each mod in its own folder with a mod.ini); tap Refresh in the manager afterwards.

The manager writes standard cpkredir.ini and ModsDB.ini files. Relative paths from desktop mod packs are also supported, so most HMM/UMM layouts can be copied without manually rewriting every path. Desktop-only code mods or mods that depend on Windows DLLs will not work on Android.

The mod manager also has a Codes section listing built-in game patches — for example Homing attack on jump, Save score at checkpoints, or Skip intro logos. Tick the ones you want and save the mod list; codes are applied on the next launch. Per-mod schema settings implement issue #75.

Updating the app

The launcher checks this repository's latest GitHub release periodically and also provides a manual Check for updates button. Downloads are limited to the official release path, checked against GitHub's SHA-256 digest when available, and must carry the same Android signing certificate as the installed app before Android's package installer is opened. Game files, saves, mods and settings remain in place during an update.

Graphics drivers

The app includes a community-built Mesa Turnip driver tuned for the Adreno devices listed above. It is selected automatically on a fresh installation. A separate Adreno 710 (Vauzi) entry bundles Vauzi-17's current 710/720/722 release for A/B testing; its Auto render mode selects Sysmem.

You can choose the driver and render mode from the game's options menu. If you want to try another driver:

1. Open the app's transfer folder in Android Files.
2. Copy a compatible ARM64 driver into driver_import — either a plain Turnip .so or a whole driver-package .zip (AdrenoTools releases; ExynosTools backend loading is experimental).
3. Start the game and select the imported driver.

Only import drivers from a source you trust. A bad or incompatible Vulkan driver can cause graphical corruption, freezes, or startup crashes. The built-in recovery path lets you return to the bundled driver if an imported one fails.

Device notes

• Adreno 710: first try Adreno 710 (Vauzi) with Render Mode Auto (Sysmem). The universal bundled driver remains available for comparison and includes a synchronization fix for early-a7xx shimmer.
• Adreno 6xx: if Auto/GMEM shows corruption, hangs, or unexpectedly low performance, try Render Mode Sysmem. It forces TU_DEBUG=sysmem; it is a workaround to test, not a universal performance win.
• Adreno 725: start with the universal bundled driver. An A725 Performance (experimental; sysmem+nobin) choice is also included for affected devices; selecting it automatically locks the required Sysmem mode and TU_DEBUG=sysmem,nobin. It is not selected by default and is not intended for Adreno 732 yet.
• Adreno 732: supported through a community device profile based on the closely related Adreno 735.
• Adreno 750: disable MSAA if you see corruption. The known issue is in the Turnip MSAA path; the default Android settings already leave anti-aliasing off.
• Adreno 720 / 722: driver entries are included, but real-device feedback is still needed.

Technical findings and current limitations for ExynosTools and PanVK are documented in docs/GRAPHICS_DRIVERS.md.

Performance on weaker devices

The Android build already defaults to a 50% resolution scale, no anti-aliasing, and motion blur off. If that is not enough, the in-game Video options offer, roughly in order of impact:

• Resolution Scale — the single biggest lever; it can go down to 25%.
• Texture Quality (Full / Half / Quarter) — loads every texture at half or quarter resolution, cutting texture memory and GPU bandwidth like a low-resolution texture pack, but covering the base game, DLC, and mods with no extra files. UI and fonts stay sharp.
• FPS cap — capping at 30 greatly reduces heat and gives steadier frame pacing on devices that cannot hold 60.
• Shadow Resolution — down to 256 for the weakest GPUs.
• Planar Reflections — turning them off stops refl
