Cracking the .sd files

[alpaca]

Well, did some work on those yesterday since we need to edit them if we actually want to add new factions (not only replace them).

In case you don't know a thing about them, the .sd files can be found in the data/ui folder and describe the images associated with ui elements (i.e. they describe which part of one of the stratpages/battlepages a ui element can be found in).

Note: This thread is meant first of all as a note to myself, but I thought somebody might be interested in it

Well, a short file definiton:

bytes			content

0-3			long: 6, probably a version id or something
4-7			long: the number of pages in this file
8-11			long: the number of entries for ui elements

n times:		files
0-3			long: string length for the file name
variable		filename
0			0x00
1-4			long: width of the page
5-8			long: height of the page
9-12			long: length of the following bitmap
width*height/8	monochrome bitmap to signify cursor state (have a bitwise 1 here, you get a highlight)

m times:		ui elements
0-3			long: string length
variable		ui tag
0-1			short: file id of the page they are specified in
2-3			short: x position of the top left corner in the page
4-5			short: x position of the bottom right corner
6-7			short: y position (top left)
8-9			short: y position (top right)
10-15			0x010000000000
