Format ANAG (ANAzawa? G?)

Binary format that contains files without name or headers.

Specification

Offset	Size	Description
0x00	0x04	Stamp ANAG
0x04	-	32-bits folder info absolute pointers
-	-	File data

The folder information has the following recursive format:

Offset	Size	Description
0x00	4	Number of children
0x04	-	32-bits file or folder info absolute pointers
-	0x04	[If last pointer for file] File end position

In this case, the pointer could be for a file or for another structure of folder information. The table ends with a pointer to the file end if the last pointer was for a file, so it can calculate the file length by subtracting the two.

The game requests files by providing the hierarchy depth and the indexes from the root folder. The subroutine that gets a file pointer is in the overlay 53 at 0x020ec210.
