Further Information
U8 archives
This part explains the relation between the file formats U8, YAZ0, SZS, WU8 and WBZ.
U8 is a file archive containing a hierarchical file system. GameCube and Wii images use U8 archives as main DVD file system. The U8 file system is optimized as read only system and support only file name, file size and a directory structure, but no other file attributes like time stamps. It's like a TAR file or like a ZIP file without compression.
To make U8 archives smaller, the compression method YAZ0 is used. A YAZ0 compressed U8 archive is usually stored as SZS file. Track files are of this format. YAZ0 is also used to compress other archives like RARC and BRRES, and some of these files are sometimes also stored as SZS file.
The file format WU8 (Wiimms U8) was developed by Wiimm to allow exchanging of custom tracks over the Internet without any Nintendo stuff and without license and copyright problems. The design is identical to the file format U8, but the sub files of the archive are patched against Nintendos original files.
WBZ is an alternative compression format for YAZ0 based on the public compression bzip2. It is dedicated to the WU8 file format to allow small files without copyrighted material. The alternative compression should also help to avoid false positives of the copyright file scanners.
Image Formats
Images of Mario Kart Wii are stored in different file formats:
- BREFT sub files (Images of some objects, with mipmap support)
- BRFNT files (font file with many images)
- BTI files (used in course.bti* files, with mipmap support)
- TEX0 files (BRRES sub file, with mipmap support)
- TPL files (may store multiple images)
All file formats use identical Image Formats and they are only different in file structure and mipmap support. mk8:List of File Formats
