The '''U8 archive''' is an archive format used in [[content.bin]] and [[opening.bnr]]. It contains no compression or encryption by itself; it is just a way to attach files in a directory structure together.  

The '''U8 archive''' is an archive format used in [[content.bin]] and [[opening.bnr]], as well as in certain games such as Mario Kart Wii and New Super Mario Brother's Wii as .arc, .carc or .szs files. It contains no compression or encryption by itself; it is just a way to attach files in a directory structure together.  

There is a tool available, [[User:Magicus/Magicus's Tools/Parse-u8.c|parse-u8.c]], which will split an U8 archive into a file structure.

For normal files, type is '''0x0000'''. In this case the data_offset gives the address to where the data for this file is. This is given as an absolute offset from the start of the U8 header. The size is the size of the file.

For directories, type is '''0x0100'''. In this case, the data_offset has no meaning. (It seems to be 0 or 1; it might signify the level of recursion even though this is redundant.) The size field is used to indicate which files are included in this directory. The value given is the node number of the last file included, counting the root node as node number 1.  

For directories, type is '''0x0100'''. In this case, the data_offset has no meaning. (It seems to be 0 or 1; it might signify the level of recursion even though this is redundant. In Mario Kart Wii U8 Files, it specifies the parent directory of the current directory, with the root directory specifying itself) The size field is used to indicate which files are included in this directory. The value given is the node number of the last file included, counting the root node as node number 1.  

An example: In opening.bnr, there are five nodes:
