Game Asset Tool

Game Asset Tool is a portable Windows tool for extracting, collecting and previewing assets from visual novels and indie games.

Drop a game folder or supported file into the window, run Dry Run / Scan, then extract only what the detected engine supports. Output is written into an extracted folder inside the selected game directory, so original files are left untouched.

What It Can Do

• Auto-detect the selected game engine.
• Extract archives and loose assets into organized output folders.
• Drag a folder or file onto the window, or directly onto GameAssetTool.exe.
• Preview results in a searchable gallery with image, SVG, audio and video filters.
• Copy the extraction summary for bug reports or support messages.
• Recover embedded PNG, JPEG, GIF, OGG, WAV and WebP files from unknown formats.
• Convert Java SVG assets to PNG previews while keeping the original SVG files.
• Install and remove the supported Ren'Py gallery unlocker.
• Use the optional Unity decensor assistant for Mono BE5, Mono BE6 and IL2CPP games.
• Run from one portable EXE. No separate Python packages or helper files are required.

Unity Decensor Assistant

For Unity games, the Unity Decensor... window can detect Mono BE5, Mono BE6 and IL2CPP setups, offer compatible BepInEx Bleeding Edge builds and install the matching embedded SW_Decensor v0.7.4.2 DLL after BepInEx has successfully launched once.

BepInEx downloads require internet access. Extraction itself works offline.

Notes And Limits

• Encrypted Godot PCK archives require a valid key.
• Some protected XP3, Unreal IoStore and custom archive formats are detected but not fully extracted.
• Unreal Oodle extraction uses a built-in open-source fallback; a local official oo2core*_win64.dll is preferred when available.
• BepInEx and SW_Decensor compatibility is not guaranteed for every Unity game, especially games with custom launchers or anti-tamper behavior.

Requirements

• Windows 10 version 1803 or later, or Windows 11
• 64-bit Windows
• No separate Python, package or .NET runtime installation required on supported Windows versions

The built-in runtime is prepared silently under %LocalAppData%\GameAssetTool\runtime\ when needed and removed when the application closes.
