<br /> [GMO] Files consist of various Chunks defining the type of data they contain, with no initial hard-coded offsets in the begining of the file. Each chunk must be parsed seperatly to determine its Type and Size, either to skip it entirey or attempt to extract the information contained within.
As such, parsing these [GMO] files is a similar mechanism to parsing generic 3DS files.
<br />
==File Header==
There is an initial 16-Byte header describing the file as a [GMO]:
<br /> After this comes the first specialised Chunk.
==Chunks==
Each Chunk contains an initial local header describing the Type and Size of the contents to come.
<br /> A number of Chunk-Types have been discovered, described in detail in the sections to follow.
=== 0x0002 - File Start ===
This Chunk can be described as the root Chunk containing all Sub-Chunks within.
<br />
===0x0003 - Sub-File===
These Chunks mark the exact nature of the Chunks which follow, and can be determined by reading the last SHORT of the chunk.
Known Values:
* 0x6f6d Models
