Wii U ROM File Format

The WUP file format is a proprietary file format used by the Nintendo Wii U video game console to store game data. WUP files contain the game code, graphics, and other data necessary to play a game on the Wii U. WUP files are typically encrypted to prevent unauthorized access to the game data. To play a WUP file, it must be installed onto the Wii U’s internal storage or a compatible external storage device. Once installed, the game can be launched from the Wii U’s menu screen.

WUP File Structure

WUP files are composed of a header followed by a series of chunks. The header contains information about the WUP file, such as the file size, the game title, and the game version. The chunks contain the game data, such as the code, graphics, and sound effects. The chunks are organized into a hierarchy, with each chunk containing a series of subchunks. The subchunks contain the individual data elements, such as the textures, models, and animations. The WUP file structure is designed to be efficient and to allow for fast access to the game data.
