''opening.bnr'' is a file found in all Wii disks which is the first file read when loading a game. It contains banner and sound for when loading a game.

= File Format =
== Header ==
The file starts with an IMET header. It has the following structure:

{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Byte[0x40] || '''Padding'''. Always 0.
|-
| 0x40 || Char[4] || '''File magic'''. Always ''IMET'' in ASCII.
|-
| 0x44 || UInt32 || '''[[#U8 File|U8]] offset'''.
|-
| 0x48 || UInt32 || '''Number of files''' in the [[#U8 File|U8]].
|-
| 0x4C || UInt32 || '''[[#banner.bin|banner.bin]] size''' in bytes.
|-
| 0x50 || UInt32 || '''[[#banner.bin|icon.bin]] size''' in bytes.
|-
| 0x54 || UInt32 || '''[[#banner.bin|sound.bin]] size''' in bytes.
|-
| 0x58 || UInt32 || '''{{Unknown-left|'''Unknown'''.}}
|-
| 0x5C || Char[0x54] || '''Japanese channel name''' stored as UTF-16.
|-
| 0xB0 || Char[0x54] || '''English channel name''' stored as UTF-16.
|-
| 0x104 || Char[0x54] || '''German channel name''' stored as UTF-16.
|-
| 0x158 || Char[0x54] || '''French channel name''' stored as UTF-16.
|-
| 0x1AC || Char[0x54] || '''Spanish channel name''' stored as UTF-16.
|-
| 0x200 || Char[0x54] || '''Italian channel name''' stored as UTF-16.
|-
| 0x254 || Char[0x54] || '''Dutch channel name''' stored as UTF-16.
|-
| 0x2A8 || Byte[0x348] || '''Padding'''. Always 0.
|-
| 0x5F0 || Byte[0x10] || '''MD5 checksum''' of file data (0x0000 – 0x5EFF).
|}

== U8 File ==
After the [[#Header|IMET header]] comes an [[U8]] file. This file contains three different files:

{| class="wikitable"
! File name !! Description
|-
| [[#banner.bin|meta/banner.bin]] || Contains the images and animation displayed when the channel is selected.
|-
| [[#icon.bin|meta/icon.bin]] || Contains the images and animation displayed when the channel is in the menu.
|-
| [[#sound.bin|meta/sound.bin]] || Contains the audio that is played when the channel is selected.
|}

All files inside the [[U8]] starts with the following structure:

{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Magic'''. Always ''IMD5'' in ASCII.
|-
| 0x04 || UInt32 || '''File size''' in bytes, excluding this structure.
|-
| 0x08 || Byte[8] || '''Padding'''.
|-
| 0x10 || Byte[0x10] || '''MD5 checksum''' of the file data following this header.
|}

All files may be compressed using LZ77. If so, the first 4 bytes will be "LZ77". Note that the actual file starts after the IMD5 header, so if the file is compressed, bytes 0x20 – 0x23 will be "LZ77".
