IzunaRecomp for Ninja Gaiden II received its first public release for Windows on November 3, 2026. The indie project adapts the original Xbox 360 edition through static recompilation and adds the Vulkan renderer called Kasumi. The release v0.2.0 has a ZIP package for Windows, but does not include commercial game files.

What is IzunaRecomp?

The repository maintained by YaibaKamikaze describes IzunaRecomp as a fork that started from Ninja's Dawn, another unofficial recompilation of the original Ninja Gaiden II for Xbox 360. As such, this is neither Ninja Gaiden Sigma 2 nor the Ninja Gaiden 2 Black remaster.

The main change is in the graphics system. The game's PowerPC code is converted before execution to x86-64 instructions, while the Kasumi Renderer uses Vulkan and recompiles shaders found in the game copy itself. The author states that the renderer replaces the emulated GPU approach used in the previous base. This is a technical description of the project, not an independent performance test.

IzunaRecomp offers resolution options from 720p to 2160p, vertical sync, anisotropic filtering, anti-aliasing, and frame pacing settings, according to current documentation. However, choosing 4K does not guarantee a stable experience: the result depends on hardware and the stage of compatibility.

Ninja Gaiden II on PC: first public release

The file IzunaRecomp-0.2.0-windows.zip was confirmed on the official page of version 0.2.0, published on November 3. It is a package of approximately 109 MB hosted on the maintainer's GitHub. The release represents a milestone of IzunaRecomp itself, different from previous Ninja's Dawn updates.

The Allves Games had already presented the Ninja's Dawn recompilation for PC. Now, the news is the release of another project, featuring its own graphics rendering and interface, built from that base.

IzunaRecomp requirements for Windows

According to the README, the public version requires 64-bit Windows 10 or 11, a graphics card with Vulkan support, and updated drivers. The developer cites GPUs from the NVIDIA GTX 900, AMD RX 400, or Intel Arc families, or newer generations, as examples.

Additionally, it is necessary to use the data obtained from your own copy of Ninja Gaiden II for Xbox 360, extracted into a folder that contains default.xex. The project does not provide textures, videos, music, or other files from the commercial title.

The main executable ng2.exe is optimized for AVX2-compatible CPUs. For older processors, the package includes ng2-compat.exe; therefore, both must remain in the same extracted folder.

How to start version 0.2.0?

1. Access the official releases and choose the Windows package for the published version.

2. Extract the ZIP into a folder of your choice and keep all program files together.
3. Open ng2.exe. On the first run, the interface will prompt for the folder containing the files of your legitimate copy of the game.
4. Select the folder that contains default.xex and use the option START GAME.
5. Wait for the initial shader compilation. According to the documentation, the prepared files are located in %LOCALAPPDATA%\IzunaRecomp\shaders to speed up subsequent launches.

These steps reproduce the maintainer's instructions and do not equate to an installation test performed by the editorial team. It is neither necessary nor permitted to download unauthorized disk images to follow the guide.

Kasumi Renderer features and limitations

In addition to video options, the project outlines support for keyboard and controller, save importing, DLC, in-game menus, and mods. The README also discloses options to replace game content and use Lua scripts, though not all combinations have undergone independent validation.

The developer himself lists known issues: parts of certain models may become invisible, reflections and lighting effects still present differences, and stutters may occur. For now, there is a public release for Windows only. The existence of PS5-related code in the development tree does not mean that a port download for that console exists.

The maintainer also reports having used an AI coding tool during development and claims to have tested the builds on real hardware. This information belongs to the creator's account; Allves Games has not performed benchmarks, security audits, or its own full campaign testing.

Is it an official version?

No. IzunaRecomp is an independent initiative and has no association with Koei Tecmo, Team NINJA, or Microsoft. The project's code license does not extend to Ninja Gaiden II's commercial data, which still requires a copy of your own.
