<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.

Many strings.

Header String Offsets

Type Size Value Description
UInt16 2 Offset_Count Number of offsets before strings start
UInt16[Offset_Count] 2 * Offset_count Offsets The offset value points to start of a string

Can be 0x00 ignore those

String

Strings end with 0x00. Strings are encoded.
[Start of string location] = [Start of file] + [String offset value]
