BNR File Extension
Nintendo Wii Banner File – file format by N/A
BNR (Nintendo Wii Banner File) is an image file used by the Nintendo Wii console. It contains an image that is displayed when a game disc is inserted into the console. BNR files are typically small in size, ranging from a few kilobytes to a few megabytes.
BNR File Characteristics
A BNR file, short for Nintendo Wii Banner File, is a proprietary file format used exclusively by the Nintendo Wii video game console. Its primary function is to store banner images and metadata associated with various Wii channels, software, and applications. BNR files are typically located on the Wii’s internal memory or on an external SD card. Each channel or application has its own unique BNR file, which is loaded by the Wii’s operating system when the user selects the corresponding channel or application from the Wii Menu.
BNR File Structure and Contents
BNR files are binary files with a specific structure. They consist of a header section, which contains information about the size and format of the file, followed by the actual banner image data. Banner images in BNR files are typically in PNG format, although other image formats may also be supported. In addition to the banner image, BNR files may also contain additional metadata, such as the title, description, publisher, and version information of the associated channel or application. This metadata is used by the Wii’s operating system to display relevant information about the channel or application in the Wii Menu.
Opening BNR Files on Windows
To open BNR files on Windows, you will need a program that supports the Nintendo Wii Banner File format. There are several options available, but one popular choice is a file viewer called “BNR Viewer.” This free and open-source program can be downloaded from the internet and easily installed on your Windows computer.
Once installed, you can open BNR files by right-clicking on the file and selecting “Open with” from the context menu. Then, select “BNR Viewer” from the list of available programs. The program will then display the contents of the BNR file, which typically includes an image and some metadata.
Opening BNR Files on Mac
On Mac computers, you can also use BNR Viewer to open BNR files. However, you may need to install a third-party library called “libfreeimage” before you can use BNR Viewer. Once both programs are installed, you can open BNR files by double-clicking on them. BNR Viewer will automatically launch and display the contents of the file.
Technical Details
BNR files are small binary files used as resource files in Nintendo Wii games. They contain banner images displayed on the Wii menu and additional data such as icon graphics, title text, and game ratings. BNR files are typically stored within a Wii game’s “banner” folder.
Format and Structure
The structure of BNR files is relatively simple. They begin with a header containing information about the file size, format version, and other metadata. The header is followed by the banner image data, which is stored in a compressed format. Additionally, BNR files may contain an optional XML file that provides further metadata, such as the game’s title, description, and developer information.
