My Avatar Editor is a classic, web-based tool originally developed by Trevor McCauley (senocular) as a Flash application. It gained legendary status as the ultimate, unofficial Nintendo Mii creation and editing tool outside of a physical Wii or 3DS console.
While initially built during the peak of the Nintendo Wii era, the tool remains highly regarded by vintage gaming communities and solo developers who need an intuitive framework for managing visual assets. Core Purpose and Functionality
Mii Extraction and Injection: The tool’s primary draw is its ability to import and export .mii data files. This allows you to extract an avatar from a virtual console (like the Dolphin Emulator), edit it on your PC, and repackage it back into games like Mario Kart Wii.
XML Descriptor Framework: Unlike simple dress-up games that output flat images, My Avatar Editor constructs characters using structured XML files. It maps out individual facial coordinates (eyes, nose, mouth, eyebrows) and their direct scaling relationships.
Developer Backbone (Avatar Core): The underlying infrastructure was packaged into an open-source library called Avatar Core. This allowed indie game developers to implement identical, high-utility character customization menus within their own standalone game projects. Key Customization Features
The tool mimics the layout of Nintendo’s formal system, offering deep mathematical scaling that standard avatar creators lack:
Feature Positioning: You can adjust the exact height, spacing, and size sliders for facial features rather than relying on preset locations.
Color Calibration: Includes full-spectrum color wheels for hair, skin tones (complete with realistic undertones), and default clothing.
Format Exporting: Allows you to save your character designs directly to transparent PNG formats for digital profiles or retain the file as raw character code. Modern Availability
Because the original software was built on Adobe Flash, accessing it requires using archived versions or modern preservation platforms:
Flash Preservation: You can find and run the tool safely via the Flash Museum Project or the Internet Archive using built-in Flash emulators like Ruffle.
GitHub Repository: Developers can still access the complete, open-source library code directly on the senocular/avatarcore GitHub page to study how its character asset pipeline works.
