Extract text from UI parameter files (YNCP)
To convert YNCP parameters to another format, you need Hedgehog Engine Tools or other Game software.
To convert other file formats to the "Game Asset File" file type, you need software like Hedgehog Engine Tools or a similar tool.
The .YNCP file is a proprietary game asset used specifically in the video game Sonic Unleashed. It functions as a UI Parameter file, storing critical configuration data, coordinates, states, and logic for the game's menus and Heads-Up Display (HUD).
These files are processed directly by the Hedgehog Engine, developed by Sonic Team. Modding communities typically handle these files using specialized scripts or custom unpackers designed specifically for Sonic games.
Users need to edit these files to create game mods, alter the user interface, or translate menu text. The main disadvantage of the .YNCP format is its completely closed and proprietary design. It requires specific community tools to read. Standard text editors or browsers cannot open it, and viewing it directly often results in an unreadable binary mess. It has zero utility outside of modifying Sonic Unleashed.
The best conversion targets are structured data formats like XML or JSON. Converting to these formats allows modders to manually edit the UI coordinates and logic before packing them back into a .YNCP file for the game engine to read. Note that converting to plain TXT will lose the hierarchical structure necessary for repacking the file correctly.
Because it is a niche game asset, the .YNCP file format is exceptionally difficult to open or convert. Standard online converters fail because they lack the specific serialization schema of the Hedgehog Engine. Often, only the original engine or custom modding tools can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your YNCP file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our YNCP converter.
