'''IGZ''' is a 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]].

= File Format =
The file byte order is always little endian.

== Header ==
{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Byte || {{Unknown-left|'''Unknown'''. Always 1. Probably part of the magic.}}
|-
| 0x01 || Char[3] || '''File magic''' Always ''ZGI'' in ASCII.
|-
| 0x04 || UInt32 || '''File version'''.
|-
| 0x08 || UInt32 || {{Unknown-left|'''Unknown'''. Probably a hash.}}
|-
| 0x0C || UInt32 || {{Unknown-left|'''Unknown'''.}}
|-
| 0x10 || UInt32 || '''Number of data blocks'''.
|-
| 0x14 || UInt32 || {{Unknown-left|'''Unknown'''.}}
|-
| 0x18 || UInt32 || {{Unknown-left|Possible '''first block offset'''.}}
|-
| 0x1C || UInt32 || {{Unknown-left|'''Unknown'''.}}
|-
| 0x20 || UInt32 || {{Unknown-left|Same as '''0x18'''.}}
|-
| 0x24 || UInt32 || {{Unknown-left|'''Unknown'''.}}
|-
| 0x28 || UInt32 || {{Unknown-left|'''Offset to mesh structure'''?}}
|-
| 0x2C || UInt32 || {{Unknown-left|'''Unknown'''.}}
|-
| 0x30 || UInt32 || {{Unknown-left|'''Unknown'''.}}
|-
| 0x34 || UInt32 || {{Unknown-left|'''Unknown'''.}}
|-
| 0x38 || UInt32 || {{Unknown-left|'''Buffer data offset'''.}}
|-
| 0x3C || UInt32 || {{Unknown-left|'''Buffer data offset'''.}}
|-
| 0x40 || UInt32 || {{Unknown-left|'''Unknown'''.}}
|}

After the header there are many null bytes, and at 0x224, there are two strings following each other. How this data is handled is unknown.

== Block Header ==
Each block starts with the following header:

{| class="wikitable"
! Offset !! Type !! Description
|-
| 0x00 || Char[4] || '''Section magic'''.
|-
| 0x04 || UInt32 || '''Number of entries''' stored in the section.
|-
| 0x08 || UInt32 || '''Size of this section''' in bytes.
|-
| 0x0C || UInt32 || '''Size of this section header''' in bytes.
|}
