URKit v0.1.2

URKit v0.1.2

This release focuses on loader stability, launcher-based games, runtime detection, and safer mod activation.

Highlights

• Reworked loader initialization and lifecycle management.
• Improved compatibility with launcher-based Unity games.
• Added safer process qualification and runtime discovery.
• Improved IL2CPP and Mono runtime backend selection.
• Hardened module loading against proxy/system DLL conflicts, including version.dll-related failures.
• Prevented loader-wide crashes caused by individual mod or hook failures.
• Added safer callback and lifecycle guards.
• Improved native mod activation and failure reporting.
• Added better runtime event handling and unload cleanup.
• Preserved append-only SDK ABI compatibility for existing mods.
• Added safer metadata and runtime API access checks.
• Improved cursor and mouse-capture ownership handling.
• Added stronger protection against invalid or corrupted metadata.
• Improved diagnostics and logging for loader decisions and runtime initialization.

Compatibility

• Existing URKit mods remain compatible with the append-only SDK changes.
• Existing Mono and IL2CPP integrations are preserved.
• Mods are now isolated more safely during activation and failure scenarios.
• Launcher-based games receive more conservative runtime detection and initialization.

Reliability Improvements

• A failed mod no longer needs to terminate the entire loader.
• Runtime initialization now validates backend availability before enabling hooks.
• Native callbacks are guarded against invalid lifecycle states.
• Module and runtime discovery failures provide clearer diagnostic logs.

Validation

• Debug and Release builds completed successfully.
• Runtime loader policy tests passed.
• IL2CPP export and runtime discovery tests passed.
• Callback and lifecycle safety tests passed.

Known Notes

• This release changes loader initialization behavior to favor safety and explicit runtime validation.
• Mods relying on undocumented internal loader timing may require verification.
• Official URKit SDK-based mods should not require source changes.

v0.1.1

URKit v0.1.1

Public Release

URKit is a Windows x64 native modding SDK and runtime for Unity Mono and IL2CPP games.

Added

• Proxy-free injected loader via URKitInjector.dll.
• Manual configuration and explicit mod DLL selection for injected sessions.
• Owner-aware mouse capture API for native mod menus.
• Separate cursor visibility and mouse-input capture handling.
• Automatic cleanup of cursor and mouse-capture state when a mod unloads.
• Improved generated projects with:
  • Clang/Ninja configuration
  • VS Code IntelliSense support
  • C++20 configuration
  • Better module scanning compatibility
• Safer handling of invalid UTF-8 metadata names in the Unity inspector.
• Public release staging with SHA-256 checksums and release manifest.

Reliability

• Mod-specific configuration paths are now supported.
• Explicitly selected mod DLLs can be loaded without scanning a Mods directory.
• Runtime API tables remain append-only for ABI compatibility.
• Generated mods can check runtime capabilities and API size before using new functions.

Compatibility

• Windows x64 only.
• Supports Unity Mono and IL2CPP backends.
• Supports DX11, DX12, and OpenGL overlays.
• Generated mod DLLs require a compatible URKit loader.

Distribution

The public package includes:

• urk-sdk.exe
• version.dll
• winhttp.dll
• winmm.dll
• URKitInjector.dll

Use only one proxy DLL (version.dll, winhttp.dll, or winmm.dll) in a game directory, depending on which DLL the game imports.

The SDK is MIT-licensed. Loader binaries are distributed under the included loader binary license.

URKit v0.1.0 - Public SDK Release

URKit v0.1.0

The first public release of the URKit SDK.

Included

• Mono and IL2CPP mod development support for Windows x64 Unity games
• urk-sdk.exe for generating ready-to-build mod projects
• version.dll, winhttp.dll, and winmm.dll loader proxy options
• Unity object, scene, component, transform, input, event, coroutine, and networking helpers
• Hook utilities and main-thread callback support
• ImGui overlay support for DX11, DX12, and OpenGL

Notes

• Use only the proxy DLL imported by the target game. Do not rename proxies or place all of them in the same game directory.
• URKit does not guarantee compatibility with every Unity game. Re-test your mod after a game or Unity version update.
• For startup or loader issues, check URKit_logs.log next to the game executable.

The SDK is licensed under MIT. Loader source code remains private; release packages include compiled loader binaries only.
