Unleashed Recompiled is an unofficial PC port of the Xbox 360 version of Sonic Unleashed created through the process of static recompilation. The port offers Windows and Linux support with numerous built-in enhancements such as high resolutions, ultrawide support, high frame rates, improved performance and modding.

This project does not include any game assets. You must provide the files from your own legally acquired copy of the game to install or build Unleashed Recompiled.

Check out the latest release here.

XenonRecomp and XenosRecomp are the main recompilers used for converting the game's original PowerPC code and Xenos shaders into compatible C++ and HLSL code respectively. The development of these recompilers was directly inspired by N64: Recompiled, which was used to create Zelda 64: Recompiled.

How to Install

1) You must have access to the following:

- Xbox 360 (modifications not necessary)
- Xbox 360 Storage Device (either an Xbox 360 hard drive or an external USB storage device)
- Xbox 360 Hard Drive Transfer Cable or a compatible SATA to USB adapter (only required for dumping from an Xbox 360 hard drive)
- Sonic Unleashed for Xbox 360 (US or EU, **JP is not supported**)
    - Retail Disc or Digital Copy (can be purchased and downloaded from the [Xbox Store](https://www.xbox.com/en-US/games/store/sonic-unleashed/c098fgnmts8f)).
    - Title Update required.
    - All available DLC (Adventure Packs) are optional, but **highly recommended**. **The DLC includes high quality lighting for the entire game**.

[!TIP] If you do not have the Xbox 360 Hard Drive Transfer Cable, please ensure that you purchase the correct revision of it for your console.

The latest revision works with both original Xbox 360 and Xbox 360 S|E hard drives, but the first revision only works with original Xbox 360 hard drives.

To know which is which, the first revision cable is gray, whereas the latest revision (which supports any Xbox 360 hard drive) is black.

2) Before proceeding with the installation, make sure to follow the guide on how to acquire the game files from your Xbox 360.

- Xbox 360 Hard Drive Dumping Guide
    - [English](https://github.com/hedge-dev/UnleashedRecomp/blob/HEAD/docs/DUMPING-en.md)
- Xbox 360 USB Dumping Guide
    - [English](https://github.com/hedge-dev/UnleashedRecomp/blob/HEAD/docs/DUMPING-USB-en.md)

3) Download the latest release of Unleashed Recompiled and extract it to where you'd like the game to be installed.

4) Run the executable and you will be guided through the installation process. You will be asked to provide the files you acquired in the previous step. When presented with options for how to do this:

- **Add Files** will only allow you to provide **containers or images dumped from an Xbox 360**. These often come in the form of very large files without associated extensions. Don't worry if you're not aware of what's inside of them, the installer will automatically detect what type of content is inside the container.

- **Add Folder** will only allow you to provide a **directory with the game's raw files** corresponding to the piece of content that is requested. **It will NOT scan your folder for compatible content!**

[!NOTE] Please note that it is not possible to complete the installation if your files have been modified. In case of other problems such as black screens or crashes, do not try to reinstall the game as it is not possible for the process to result in an invalid installation.

Features

Easy to Use Installer

A built-in installation wizard will guide you through the process of installing the game with many integrity checks to ensure the process goes as smoothly as possible. The installer can also be accessed from the title screen, if you wish to add the DLC at a later time.

Options Menu

A completely new options menu accessible from the title screen or pause menu, with an unprecedented level of fidelity to the game's design language. Get access to many quality of life features and graphics options directly within the game with full controller navigation.

Achievements

You will be rewarded with achievements as you progress through the game just like on its original platform. Achievements are recreated with integrated notifications and a new menu also very faithful to the game's design language. Get all of them and you will be rewarded with a gold trophy!

[!NOTE] Achievements cannot be used with platforms such as Steam or RetroAchievements.

Custom Localization

All of the new menus in the port fully support localization for each of the game's originally supported languages; English, Japanese, German, French, Spanish and Italian. As a bonus, switching the game to Japanese also changes the title screen logo to its original Japanese counterpart.

High Fidelity

Special care and attention was taken to recreate the game's visuals as accurately as possible and was always compared to the game running on the original hardware. The colors are as vibrant as those of the PlayStation 3 version, which did not use the color correction filter present in the Xbox 360 version, as was originally intended. Nevertheless, an option to recreate the original warm filter from the Xbox 360 version has been included as an option.

High Resolution Enhancements

Many improvements have been provided to accompany support for higher resolutions:

• Multisample Anti-Aliasing (MSAA) levels beyond the 2x used by the original game.
• Higher quality Depth of Field (DoF), an effect which commonly breaks in emulators when increasing the game's resolution. The original effect's formula was reverse-engineered and versions with 5x5, 7x7 and 9x9 taps were added based on the target resolution.
• An "Enhanced" Motion Blur option which uses more samples than the original for a smoother blur.
• Support for "Alpha to Coverage" Anti-Aliasing to enhance the visual result of transparent textures with hard edges.
• A Bicubic Texture Filtering option which greatly enhances the visual result of Global Illumination textures.
• A more precise implementation of the game's reverse Z technique, eliminating most Z-fighting issues and fixing the jittery motion blur in stages like Jungle Joyride.

High Performance Renderer

A new renderer was written from scratch to translate the game's draw calls to modern APIs in a highly efficient way while also taking advantage of multi-threading.

As emulation of the Xbox 360's GPU is not required in a recompilation, many decisions were made to skip quirks of the original hardware that are not required in a PC port, resulting in great improvements to performance.

Modern rendering techniques such as bindless textures and shader specialization are also used to maximize the performance on systems with modern hardware whilst also supporting a wide range of lower end hardware.

Multiple optimizations were made to the game's shadow map rendering and special techniques were developed to automatically detect and skip unnecessary texture copies that are no longer needed in modern APIs.

Additionally, to support the game's extensive use of asset streaming, parallel transfer queues are leveraged, a feature only available in modern APIs that enable efficient use of available PCI-E bandwidth.

High Frame Rate Support

The game's frame rate cap has been increased by default to 60 FPS, with support for higher targets and unlocked frame rate being available from the options menu. A vast amount of glitches that usually occur at higher frame rates have been fixed and are included as part of the recompilation.

[!NOTE] While the game is considered to be beatable at frame rates higher than 60 FPS, please note that some issues can still occur. Some of these issues may be addressed in future updates.

Ultrawide Support

Aspect ratios for ultrawide displays (such as 21:9 or even wider) are supported out of the box, with options to adjust the alignment of the UI to the edges or to the original 16:9 safe area, if desired. No external codes are required!

[!NOTE] By default, cutscenes are locked to their original aspect ratio to prevent presentation issues, as the game was not designed to present these scenes with wider aspect ratios. However, you can use the included option to unlock this feature if you don't mind these issues.

Extended Controller Features

Support for the D-Pad has been added to various parts of the game, allowing the full game to be completed using it over the analog stick, if you so desire.

If you have a DualShock 4 or DualSense controller, the LED will dynamically change color depending on the game context and support for the touchpad has been added to the World Map, allowing you to spin the planet freely!

[!NOTE] LED and touchpad support for the DualShock 4 and DualSense controllers may be limited when using third-party input translation layers (such as DS4Windows or Steam Input).

Support for both features may also be limited on Linux.

Low Input Latency

Modern input latency reduction techniques are included to improve the game's responsiveness as much as possible, such as support for Waitable Swap Chains in both D3D12 and Vulkan. This methodology was applied directly before the game's input polli
