'''AAR''' ('''A'''qualead '''AR'''chive) is an archive format developed by [[Aqualead]] and found in some [[Wii]] and [[3DS]] games (and suspected to be used in [[GameCube]] titles as well), such as ''[[One Piece: Unlimited Adventure]]'', ''[[One Piece: Unlimited Cruise Episode 1 - The Treasure Beneath The Waves]]'', ''[[One Piece: Unlimited Cruise Episode 2: Awakening of a Hero]]'', ''[[One Piece: Unlimited Cruise SP]]'' and ''[[One Piece: Unlimited Cruise SP 2]]''.

= File Format =
The file byte order can be either big endian (Wii) or little endian (3DS).

== Header ==
The file starts with the following header:

{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''File magic'''. Always ''ALAR'' in ASCII.
|-
| 0x04 || Byte || '''[[#Version List|Version number]]'''.
|-
| 0x05 || Byte || {{Unknown-left|'''Unknown'''.}}
|-
| 0x06 || UInt16 || '''Number of [[#File Entry|file entries]]'''.
|-
| 0x08 || Byte || '''Padding'''.
|-
| 0x09 || UInt24 || '''Unix timestamp''' without year of the file's creation date.
|-
| 0x0C || Byte || '''Padding'''.
|-
| 0x0D || UInt24 || '''Unix timestamp''' without year of the file's last modification date.
|}

== File Entry ==
Each file entry has the following structure:

{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Byte || '''File type''':
* 0x00 = Other/No extension
* 0x40 = Texture ([[ATX]], [[TPL]])
* 0x41 = Motion ([[AMT]])
* 0x42 = Image ([[AIG]], [[TGA]])
* 0x43 = Assemble/resource ([[AOD]])
* 0x44 = Mesh ([[AMS]])
* 0x45 = Palette
* 0x46 = Tilemap
* 0x47 = Archive (AAR)
* 0x48 = Sound
* 0x49 = Table definition
* 0x4A = Table ([[ATB]])
* 0x4B = Shader ([[ASD]])
* 0x4C = Script (NUT)
* 0x4D = Font ([[AFT]])
* 0x4E = ID mask
* 0x4F = Extension mask
|-

|-
| 0x04 || UInt32 || '''File data offset'''.

| 0x08 || UInt32 || '''File size''' in bytes.
|-
| 0x0C || Byte[4] || {{Unknown-left|'''Unknown flags'''. Always 0x80000001.}}
|}

== File Data ==
After all nodes comes all the file data, with the file names 0x24 bytes before the data itself. There is a 2 0-byte padding before the name with unknown reason, and a UInt16 before the file data.

= Version List =
