-OpenTTD: OS/2 version
-=====================
-
-OpenTTD has been ported to work on OS/2 4.x or later (including
-eComStation). The game should work as well as it does on Windows
-or other platforms: the main issues you may encounter are graphics
-card problems, but that is really the fault of SDL.
-
-=========================
-USING OPENTTD FOR OS/2
-=========================
-
-LIBRARIES REQUIRED FOR END USERS
--------------------------------
-
-SDL.DLL (SDL 1.2.7) and FSLib.dll are required to use this program:
-these can be downloaded from the Files section at
-http://sourceforge.net/projects/openttd/ - see "os2-useful-v1.1.zip".
-Version 20051222 of SDL or later is required. This can be found at
-http://sdl.netlabs.org/.
-
-Please note that earlier SDL releases will probably NOT work with
-OpenTTD. If you experience problems with OpenTTD, please check
-your SDL and FSLib.dll versions (both must match).
-
-Note that to actually play the game, I have found in my own
-experience that a version of the Scitech Display Drivers or its later
-incarnation (see www.scitech.com) are necessary for it to work. If
-you have trouble with your native drivers, try the Scitech drivers
-and see if they help the problem.
-
-KNOWN ISSUES
------------
-
- If an error occurs during loading, the OS/2 error message window
-  is not always displayed.
-
-A NOTE ABOUT MUSIC
------------------
-
-OpenTTD includes a music driver which uses the MCI MIDI system. Unfortunately,
-due to the lack of proper MIDI hardware myself, I have been unable to test it,
-but during testing, I found that when MIDI was enabled, I got no sound
-effects. I therefore decided to DISABLE music by default.
-
-To enable music, start OpenTTD with the command line:
-
-   openttd -m os2
-
-If I hear enough responses that both music and sound work together (it might
-just be my system), I'll have the defaults changed.
-
-A NOTE ABOUT DEDICATED MULTIPLAYER SERVERS
------------------------------------------
-
-To start a dedicated multiplayer server, you should run the dedicated.cmd
-file. This enables OpenTTD to open up a VIO console window to display
-its output and gather any necessary input. Running "openttd -D"
-directly will result in the console not being displayed. You may
-still pass any other parameters ('-D' is already passed) to
-dedicated.cmd.
-
-=========================
-BUILDING THE OS/2 VERSION
-=========================
-
-Compiler
--------
-
-Open Watcom 1.3 was used to build OpenTTD (earlier versions will
-NOT work). See http://www.openwatcom.org/ to download it. It may
-also be possible to build OpenTTD with GCC: I attempted this
-before using Open Watcom, but found the tools available for OS/2
-at the time to be a bit more tricky to get working.
-
-Due to complexities in my set-up, I actually used the Win32 version
-of Open Watcom to initially compile OpenTTD for OS/2. There should
-be no reason of course why the OS/2 version cannot be used, and I
-have subsequently built OpenTTD successfully this way.
-
-Libraries Required
------------------
-
-The following libraries are required. To build zlib and libpng, I
-simply added the required files (watch out for sample programs, etc)
-to an IDE project file and built a library. Do not use the makefiles
-provided, they are not designed for Watcom (apart from SDL):
-
- zlib
-  http://www.zlib.org/ - contains a makefile for OS/2, but is out
-  of date and uses EMX, ignore this
-
- libpng
-  http://www.libpng.org/ - contains an EMX/gcc makefile, ignore this
-
- SDL for OS/2
-  ftp://ftp.netlabs.org/pub/sdl/sdl-1.2.7-src-20051222.zip used for
-  0.4.7
-
-If you do not wish to build the libraries yourself, pre-built versions
-can be downloaded from the Files section at
-http://sourceforge.net/projects/openttd/ - see "os2-useful-v1.1.zip".
-
-A Note About Subversion Revision Numbers
----------------------------------------
-
-The project file uses a bit of a hack to find out the SVN revision number and
-create an appropriate rev.c file. You'll need the SVN tools in your path
-(specifically, "svnversion"). If "svnversion" can't be found, a generic rev.c
-with the revision set to "norev000" will be created. To specifically force a
-version number, set the environment variable "RELEASE" to the number (eg, "0.3.6")
-before- starting the Open Watcom IDE (which must be launched from the same shell
-session). Also, beware, as you WILL cause incompatibilities if you try to
-play a multiplayer game with a different version.
-
-Compiling
---------
-
-To compile, open the os/os2/openttd.wpj file in the IDE and first build
-the strgen.exe target. This will build the .lng file generator, and will
-also attempt to build all the language files (plus the table\strings.h
-file which is required for openttd.exe to be built). Once strgen.exe and
-the language files are built successfully, you can build the openttd.exe
-target.
-
-Contact Information
-------------------
-
-If you have any questions regarding OS/2 issues, please contact me
-(owen@owenrudge.net) and I'll try to help you out. For general OpenTTD
-issues, see the Contacting section of readme.txt.

+OpenTTD: OS/2 version  ** CURRENTLY INCOMPLETE **
+=====================
+
+OpenTTD has been ported to work on OS/2 4.x or later (including eComStation). At the moment, it does not work properly, but it
+can compile and work to an extent.
+
+Compiler
+--------
+
+Open Watcom 1.3 was used to build OpenTTD (earlier versions will NOT work). See http://www.openwatcom.org/ to download it.
+It may also be possible to build OpenTTD under OS/2: I attempted this before using Open Watcom, but found the tools available

+
+Libraries Required
+------------------
+
+The following libraries are required. To build zlib and libpng, I simply added the required files (watch out for sample
+programs, etc) to an IDE project file and built a library:
+
+- zlib
+  http://www.zlib.org/ - contains a makefile for OS/2, but is out of date and uses EMX

+- SDL for OS/2
+  I used ftp://ftp.netlabs.org/pub/sdl/SDL-1.2.7-src-20040908a.zip - take SDL.dll and SDL.lib from the src/ directory.
+
+Note that to use the compiled program, you also need FSLib.dll (from src/ in the SDL zip) and a version of the Scitech
+Display Drivers or its later incarnation (see www.scitech.com).
+
+Compiling

+
+To compile, open the os/os2/openttd.wpj file in the IDE and build the openttd.exe target.

-Compiling OpenTTD using Microsoft Visual C++ 6.0
-
-
-Step 1: Ingredients
-
-Download the following files:
-
-    * Openttd-useful.zip (http://sourceforge.net/project/showfiles.php?group_id=103924&amp;package_id=114307&amp;release_id=228633)
-    * DirectX 8.1 SDK (http://neuron.tuke.sk/~mizanin/eng/Dx81sdk-include-lib.rar) (or alternatively the latest DirectX SDK from Microsoft)
-    * The February 2003 Microsoft Platform SDK (http://www.microsoft.com/msdownload/platformsdk/sdkupdate/XPSP2FULLInstall.htm) (newer SDK's do not work with MSVC6)
-    * afxres.h (http://www-d0.fnal.gov/d0dist/dist/packages/d0ve/devel/windows/AFXRES.H) (maybe you not need this)
-
-...and of course the newest source from svn://svn.openttd.org/trunk
-
-You have to have a SVN-client to download the source:
-
-    * Command line version (Subversion 1.2.3 Win32 binaries) (http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91)
-    * GUI TortoiseSVN (http://tortoisesvn.tigris.org/download.html)
-
-Step 2: Includes and Libraries
-
-Put the newly downloaded files in the VC lib and include directories (Where "C:\Program Files\Microsoft Visual Studio\VC98" is your local location of VC)
-
-
-    * zconf.h [useful.zip]
-    * zlib.h [useful.zip]
-    * png.h [useful.zip]
-    * pngconf.h [useful.zip]
-    * afxres.h
-
-in
-
- C:\Program Files\Microsoft Visual Studio\VC98\Include
-
-and
-
-    * zlibstat.lib [useful.zip]
-    * libpng.lib [useful.zip]
-
-in
-
- C:\Program Files\Microsoft Visual Studio\VC98\Lib
-
-
-Step 3: DirectX SDK
-
-(This should work with the latest DirectX SDK as well.)
-
-There are 2 folder in the compressed file: Include and Lib
-
-Copy all files from Include folder to
-
-C:\Program Files\Microsoft Visual Studio\VC98\Include
-
-and all files from Lib folder to
-
-C:\Program Files\Microsoft Visual Studio\VC98\Lib
-
-
-
-You can also make custom directories, which is recommended so you don't overwrite VS6 files, for libraries (.lib) and includes/header files (.h) and add it to the VC paths via:
-
-Tools -> Options -> Directories -> show directories for:
-
-a) include files (the include dir: C:\Program Files\Microsoft Visual Studio\VC98\DirectX 8.1 SDK\include )
-
-b) library files (the lib dir, C:\Program Files\Microsoft Visual Studio\VC98\DirectX 8.1 SDK\lib )
-
-NOTE: make sure that the directory for the DirectX SDK is the first one in the list, above all others, otherwise compilation will most likely fail!!
-
-Step 4: TTD Graphics files
-
-Copy the following files from Transport Tycoon Deluxe to the data folder
-
-    * sample.cat
-    * trg1r.grf
-    * trgcr.grf
-    * trghr.grf
-    * trgir.grf
-    * trgtr.grf
-
-
-Step 5: Compiling
-
-Open trunk/openttd.dsw
-
-Build menu > Set active configuration > Select: "openttd - Win32 Release"
-
-Compile...
-
-
-Now it should work, it worked for me :)
-
-From r1319 you can compile branch/map in Debug mode (by Bociusz)
-
-For compiling branch/cargo-packets you have to add cargo.c and .h to this tree's openttd.dsp
-
-If it's not working, and you checked that you using the newest SVN (!) report to Bociusz on IRC (irc://irc.freenode.net/openttd)

+Step 2
+------------------
+Put the newly downloaded files in the VC lib and include directories
+(Where D:\program files\ is your local location of VC)
+
+
+* zconf.h		[useful.zip]
+* zlib.h		[useful.zip]
+* afxres.h	
+in
+  D:\Program Files\Microsoft Visual Studio\VC98\Include
+
+* zlibstat.lib		[usefull.zip]
+* SDL.lib		[SDL.zip
+* libpng.lib		[usefull.zip]
+in
+  D:\Program Files\Microsoft Visual Studio\VC98\Lib
+
+You can also make custum directories, for libraries (.lib) and includes/header files (.h) and
+add it to the VC paths via: 
+Tools -> Options -> Directories -> show directories for:
+a) include files (the include dir: D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\include )
+b) library files (the lib dir, D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\lib )
+
+
+Step 3: DirextX SDK
+------------------
+(This should work with the latest DirectX SDK as well.)
+The installation with DirectX 7 was odd, so you'd better use the version available via the forum, see also
+the download link on top.
+
+Copy the DirectX 7 SDK files, leaving the directory stucture intact, to the directory:
+  D:\Program Files\Microsoft Visual Studio\VC98\
+thus resulting in
+  D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\include and
+  D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\lib
+
+Step 3.1
+
+Add these two folders to the search path of VC.
+In VC6.0: Tools -> Options -> Directories -> show directories for:
+a) include files (the include dir: D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\include )
+b) libraru files (the lib dir, D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\lib )
+
+
+Step 4
+-----------------
+Copy the following files from Transport Tycoon Deluxe to the data folder
+  sample.cat
+  trg1r.grf
+  trgcr.grf
+  trghr.grf
+  trgir.grf
+  trgtr.grf
+
+(Alternatively you can use the TTD GRF files from the DOS version: TRG1.GRF, TRGC.GRF, TRGH.GRF, TRGI.GRF, TRGT.GRF. Those filenames have to be uppercase to be detected correctly. A few minor graphical glitches with the DOS graphics remain. E.g. the autorail button in the rail toolbar doesn't look as nice as with the Windows graphics.)
+
+Step 5
+-----------------
+Compile ...
+
+
+Step 6
+-----------------
+
+Now it should work, it worked for me :)
+
+Go ahead and make that patch!
+
+Happy Hacking!

-Five attributes hold the information about a tile.
-These attributes are referred to as
-  "<span style="font-weight: bold;">type_height</span>",
-  "<span style="font-weight: bold;">m1</span>",
-  "<span style="font-weight: bold;">m2</span>",
-  "<span style="font-weight: bold;">m3</span>",
-  "<span style="font-weight: bold;">m4</span>" and
-  "<span style="font-weight: bold;">m5</span>".
-The most important value is the class of a tile, stored in the upper 4 bits of the type_height array.
-The lower 4 bits are used to encode the height and slope data.
-For a graphical represenation of the tile-layout have a look at <a href="landscape_grid.html">Landscape grid</a> page.
+Five arrays are used to encode the information of the contents of each tile. These arrays are referred to as <a href="#_landscape1">map_owner</a>, <a href="#_landscape2">map2</a>, <a href="#_landscape3">map3_lo</a>, <a href="#_landscape4">type_and_height</a> and <a href="#_landscape5">map5</a>. The known encodings are listed in the table below. The most important value is the class of a tile, stored in the upper 4 bits of the type_and_height array.
