'''PAK''' is a container file format used in games developed by [https://www.vvisions.com/ Vicarious Visions], such as ''Marvel Ultimate Alliance 2'', ''Crash Bandicoot N. Sane Trilogy'' and [[Crash Team Racing Nitro-Fueled]].<br />
<br />
= File Format =<br />
The file byte order is always little endian.<br />
<br />
== Header ==<br />
{| class="wikitable"<br />
! Offset !! Type !! Description<br />
|-<br />
| 0x00 || Char[4] || '''File magic'''. Always ''IGA\u001A''.<br />
|-<br />
| 0x04 || UInt32 || '''File version'''.<br />

| 0x08 || UInt32 || {{Unknown-left|'''Unknown'''.}}<br />

| 0x24 || UInt32 || '''Size of table 2''' in bytes.<br />
|-<br />
| 0x28 || UInt32 || '''String table offset'''. Points to an array of UInt32s, which points to null-terminated strings.<br />

== Hash List ==<br />
After the header comes a hash list of the files. Presumably these are hashes of the filename, since the file entries are sorted by this hash. Each entry is a 32-bit value.<br />
<br />
== File Entry ==<br />
The hash list follows by an array of file entries. Each entry has the following structure:<br />
{| class="wikitable"<br />
! Offset !! Type !! Description<br />
|-<br />
| 0x00 || UInt32 || '''File data offset'''.<br />
|-<br />
| 0x04 || UInt32 || {{Unknown-left|'''Ordinal'''.}}<br />
|-<br />
| 0x08 || UInt32 || '''File data size'''.<br />
|-<br />
| 0x0C || UInt32 || '''Flag'''. 0xFFFFFFFF means it's not compressed. xx'''A'''x xxxx xxxx xxxx xxxx xxxx xxxx xxxx.<br />
* '''A''': Compression method. Deflate = 0, LZMA = 1<br />
