+Chaos Gate. The project began with a Chaos Gate recreation, then more games were
+discovered, so scope expanded. A rename and/or rewrite may be on the cards as a
+result.
 
 ## Current status
 
+### Chaos Gate
+
 Some of the original file formats are either partially or fully decoded. Maps,
 menus, and most visual data can be rendered pixel-perfect. Sound can be played
 (with a preprocessing step). Some UI tookit work is done. No game mechanics are
 implemented yet.
 
+I keep a GIF showcasing interesting progress here:
+
+![](https://ur.gs/img/ordoor-main-menu.gif)
+
+I've just been informed that another game from 1998, [Soldiers At War](https://en.wikipedia.org/wiki/Soldiers_at_War),
+seems to use the same engine. Maybe at some point Ordoor will be able to play
+both. Will that need a rename? Hmm. Watch this space.
+
+### Soldiers At War
+
+(At least some) objects display. Map support is being worked on in the
+`soldiers-at-war` branch, which can more-or-less display them, albeit with many
+errors.
+
+### Squad Leader
+
+Squad Leader is the most recent of the games created with this engine. Nothing
+has been done with it yet, but a preliminary look at the game data suggests many
+changes are afoot. The object files are a different format, at the very least.
+
+### Wages of War
+
+This is the oldest of the four games. The object file format seems to be mostly
+the same. the installer only copies some data to the game directory; we may want
+to work directly from the CDROM instead, if we can.
+
+Maps are uncompressed, around 243K, and no header is present. They look similar
+in principle to the tile data of Soldiers At War or Chaos Gate maps, otherwise.
+
+The menu system seen in Chaos Gate is not present; instead, there is a `BUTTONS`
+directory and a lot of `pcx` files under `PIC` that, I suspect, do the job for
+this game.
+
+Even with a full installation, Wages of War leaves a lot of data on the CD. It
+may be best to run solely from the `WOW` directory on the CD, assuming it's a
+strict superset of what gets installed, data-wise.
+
+## Long-term goals
+
+Once full playthrough of the official single-player campaign for all four games
+has been achieved, thoughts turn to other things we could do. Here are some
+ideas, mostly at random.
+
+Multi-player support.
+
+Graphics enhancements - 3D models instead of sprites, high-resolution tile sets,
+32-bit colour, etc. Hopefully we'd be able to drop these in one at a time.
+
+Vastly improved AI.
+
+Mash-ups? How do mercenaries fare against cultists fare against Nazis? Only one
+way to find out!
+
+New campaigns with existing assets. Tell new stories, or elaborate on / modify
+existing ones.
+
+Completely new fantasy game using the same engine.

+Relative offsets from the start of the trailer, we have:
-assume these are all a fixed number of fixed-size records when looking into it.

+| Offset   | Text |
+| -------- | ---- |
+| `0xEE`   | Mania |
+| `0x78A`  | Dagon |
+| `0xE26`  | Nihasa |
+| `0x14C2` | Samnu |

+| `0x35ce` | Baalberith |
+| `0x3c6a` | Fenriz |
+| `0x4306` | #Character |
+| `0x49a2` | Apollyon |
+
+So there are 1692 bytes between each name (the names probably don't come at the
+start of each block, but it's still a useful stride). Presumably `#Character` is
+a space for one of the player characters, while the others specify an NPC placed
+on the map.
+
+There's 56 of these records between the first and last name we see - `Ahpuch`.
+
+Then there are a number of other strings that seem related to triggers / events,
+including lots that say `NO FILE`. The first two are 96 bytes apart; from then
+on they seem to be placed variably apart from each other; I've seen 96, 256, and
+352 byte offsets.
+
+At 0x20916 the mission objective is readable.
+
+At 0x2092a the mission description is readable.
+
+Generating another map with just 5 characters on it, things look different:
+
+* Trailer size is 13543 bytes
+* There are only 5 names
+* There are none of the trigger/event strings
+* Mission title is found at 0x2b93
+* Mission briefing is found at 0x2c92
+
+Since the trailer is a variable size, there must be a header that tells us how
+many of each type of record to read. Peeking at the differences in `vbindiff`:

+The size of the trailer for Chapter01 is 139,483 bytes, assuming it starts at
+`0x163890`. However, things may be a lot more sensible if we drop 3 bytes off
+the start of that to get the fields into little-endian alignment. Have I made a
+maths error above somewhere? Is it some sort of alignment thing? Do those 3
+bytes actually have meaning?
+
+Ignoring them for now, here's a first guess at a header:
+
+| Offset | Size | Meaning |
+| ------ | ---- | ------- |
+| 0      | 4    | Map maximum X + 1 |
+| 4      | 4    | Map maximum Y + 1 |
+| 8      | 4    | Map minimum X |
+| 12     | 4    | Map minimum Y |
+| 16     | 4    | Number of character records |
+| 20     | 4    | Padding? - invariant `00 00 00 00` |
+| 24     | 2    | ??? - varies. Seems related to character/squad position? |
+| 26     | 2    | ??? - invariant `00 04` |
+| 28     | 4    | ??? - varies (0 vs 5) |
+| 32     | 4    | Number of thingies (26 vs 1) |
+| 36     | 20   | Padding? |
+
+56 bytes of data is interesting because the value of that first, ignored byte is
+0x38 - perhaps it's a skip value + 2 bytes of padding? It's just weird. Keep
+ignoring it for now.
+
+0x4b contains the next non-null byte; is the gap between the the number of
+thingies, and it, padding? Minus a bit? 0x50 is another non-null byte. Then
+it's all zeroes until one byte before the first name at 0xee.
+
+It's hard to say where the alignment should be at this point. We need to compare
+more characters with each other. Other notes...
+
+Characters are organised into Squads somehow.
+
+Individual cells seem to have a flag to say "We have a character in us", but not
+the number for the character themselves, so the coordinates must be in the
+per-character records also. There are several candidates for this.
+
+Placing a single character at (64,49) causes those bytes to show up at four
+offsets - 0x18 (!), 0x1F4, 0x1F8, and 0x6C8.
+
+Generating a map with no characters at all, the trailer is 2,447 bytes, and the
+mission title starts at 0x3B (59). So we can say we have 20 bytes of padding as
+a first approximation?
+
+The "trailer trailer", for want of a better term, seems to be organised as:
+
+| Offset | Size | Meaning |
+| -----  | ---- | ------- |
+| 0      | 255  | Title   |
+| 255    | 2048 | Briefing |
+| 2304   | 85   | ??? - each byte is 1 or 0. Spaced so it may be partly uint32 |
+
+
+## Soldiers At War
+
+All the above applies to Chaos Gate maps. Maps for Soldiers At War seem to have
+a lot of similarities, but also some differences. For a start, the maps are a
+variable size!
+
+Starting with the header, given a tiny 26x20 generated map, the first 256 bytes
+look like this:

+
+Almost everything we knew is out of the window, but a few things look familiar.
+First, the header seems simplified down to just two recognisable-at-first-glance
+fields: Magic bytes (now `\x15\x00AMV_MAP\x00`) and the set name, coming
+immediately after.
+
+Like Chaos Gate, all map files are the same size once uncompressed, but they are
+smaller - at 1,214,559 bytes, they are 76% the size. This is quite significant.
+We now have 13.3 bytes per voxel, rather than the 17.5 bytes per voxel that was
+available to Chaos Gate. This means that the number of bytes *per cell* must be
+reduced, in addition to the header (and trailer?) values.
+
+Looking at data from 0x110, it seems to group naturally into 13-byte records:
+
+```
+$ xxd -s 0x110 -c 13 -l 65 -g 1 TINYMAP.MAP 
+00000110: 80 01 00 00 00 00 00 ff 00 00 1f 00 00  .............
+0000011d: 85 01 00 00 00 00 00 ff 00 00 1f 00 00  .............
+0000012a: 82 01 00 00 00 00 00 ff 00 00 1f 00 80  .............
+00000137: 82 01 00 00 00 00 00 ff 00 00 1f 00 00  .............
+00000144: 82 01 00 00 00 00 00 ff 00 00 1f 00 80  .............
+```
+
+It's a strange number. Chaos Gate cells group nicely on 16 bytes:
+
+```
+$ xxd -s 0x110 -c 16 -l 64 -g 1 Chapter01.MAP 
+00000110: 3f 00 00 00 83 01 00 00 00 00 00 ff 00 00 00 00  ?...............
+00000120: 38 00 00 00 85 01 00 00 00 00 00 ff 00 00 00 00  8...............
+00000130: 38 00 00 00 84 01 00 00 00 00 00 ff 00 00 00 00  8...............
+00000140: 38 00 00 00 8a 01 00 00 00 00 00 ff 00 00 00 00  8...............
+00000150: 38 00 00 00 83 01 00 00 00 00 00 ff 00 00 00 00  8...............
+```
+
+That grouping is very enticing, though. I feel strongly that it's the right
+number.
+
+Now we need to ask about start offset. Where is byte 0 of the per-cell data, and
+do the 13 bytes it has line up neatly to the functions of some of the 16 bytes
+seen in Chaos Gate?
+
+I generated a `BIGGESTMAP` (130x100) to investigate. It's just grass, nothing
+but grass, and 0xC0 is the first offset where it starts to look nicely grouped:
+
+```
+xxd -s 0xc0 -c 13 -l 260 -g 13 BIGGESTMAP.MAP
+000000c0: 08 80 81 01 00 00 00 00 00 ff 00 00 1f  .............
+000000cd: 00 80 81 01 00 00 00 00 00 ff 00 00 1f  .............
+000000da: 00 00 81 01 00 00 00 00 00 ff 00 00 1f  .............
+000000e7: 00 00 85 01 00 00 00 00 00 ff 00 00 1f  .............
+# ...
+```
+
+This can be interpreted more or less the same way as the Chaos Gate maps now,
+and the `soldiers-at-war` branch contains a hacked-up implementation that kind
+of works \o/.
+
+Does the same trailer apply? Seemingly not. Looking at `PARIS.MAP`, there's no
+similarity at first glance.
+
+However, I did manage to track down 4 32-bit ints inside the trailer, starting
+at `0x121ad1`, which specify dimensions of the map, at least. Perhaps the
+position has moved, but some of the data is the same? It's 3320 bytes into the
+trailer.

-To build this palette, I did the following:
-
-* Created the .asn + .obj files by hand
-* Referenced them in a .set file and asked WH40K_TD.exe to render the sprites
-* Screenshotted the output and used GIMP to create a 1x255 image with them all
-* Exported that image as an ASCII .ppm file
-* Used the `generate_palette` script to output Go code \o/
-
-Note that palette index 0 is ignored, and hardcoded to be transparent black.
-This is because 0x00 seems to be used as a record separator in .obj files, so
-can't be used as a palette index anyway.
