-32bpp and OpenTTD
-=================
-
-OpenTTD has 32bpp support. This means: OpenTTD still is 8bpp, but it has the
-posibility to override the graphics with 32bpp. This means that it isn't a
-replacement of grf or newgrf, but simply an addition. If you want to use 32bpp
-graphics of a newgrf, you do need the newgrf itself too (with 8bpp graphics).

-32bpp images are stored in PNG. They should go in:
-  data/sprites/<grfname>/<SpriteID>.png
-
-For example, a grfname would be 'openttd' (without .grf, lowercase), and the
-SpriteID 3, to override the 3rd sprite in openttd.grf with a 32bpp version.
-
-The format of this PNG can be almost anything, but we advise to use RGBA
-format. Alpha-channel is fully supported.
-
-As the core of OpenTTD is 8bpp, and because you of course want company colours
-in your images, you will need to add a mask for every sprite that needs colour
-remapping. The name is simular as above, only you have to put a 'm' behind the
-SpriteID. This image should be a 8bpp palette image, where the palette is the
-OpenTTD palette. Upon load of the PNG, the mask is loaded too, and overrides
-the RGB (not the Alpha) of the original PNG image, and replacing it with a
-8bpp color remapped and converted to 32bpp.
-
-An other thing that OpenTTD needs in your png, is 2 tEXt chunks: x_offs and
-y_offs. This to define the x- and y-offset, of course. Use the tool we supply
-to add this information. Sadly enough most graphical editors trashes those
-chunks upon save, so you have to readd it every time you save your image.
-
-Your images should be the same as the grf, in size.

-STRGEN USAGE
-------------
-This guide is only interesting for people who want to alter something
-themselves without access to WT2 (translator2.openttd.org). Please note that
-your compiled language file will only be compatible with the OpenTTD version
-you have downloaded english.txt, the master language file, for. While this is
-not always true, namely when changes in the code have not touched language
-files, your safest bet is to assume this 'limitation'.
-As a first step you need to compile strgen. This is as easy as typing
-'make strgen'. You can also download a precompiled binary from a release,
-nightly, etc.
-strgen takes as argument a txt file and translates it to a lng file, allowing
-it to be used inside OpenTTD. strgen needs the master language file
-english.txt to work. Below are some examples of strgen usage.
-
-EXAMPLES
---------
-Example 1:
-if you are in the root of your working copy (svn code), you should type
-strgen/strgen -s lang lang/english.txt
-to compile englist.txt into english.lng. It will be placed in the lang dir
-
-Example 2:
-you only have the strgen executable (no working copy) and you want to compile
-a txt file in the same directory. You should type
-./strgen english.txt
-and you will get and english.lng in the same dir
-
-Example 3:
-you have strgen somewhere, english.txt in /usr/openttd/lang and you want the
-resulting language file to go to /tmp. Use
-./strgen -s /usr/openttd/lang -d /tmp english.txt
-
-You can interchange english.txt to whichever language you want to generate a
-.lng file for.
-
-STRGEN COMMAND SWITCHES
------------------------
--v | --version
-strgen will tell what svn revision it was last modified
-
--t | --todo
-strgen will add <TODO> to any untranslated/missing strings and use the english
-strings while compiling the language file
-
--w | --warning
-strgen will print any missing strings or wrongly translated (bad format)
-to standard error output(stderr)
-
--h | --help | -?
-Print out a summarized help message explaining these switches
-
--s | --source_dir
-strgen will search for the master file english.txt in the directory specified
-by this switch instead of the current directory
-
--d | --dest_dir
-strgen will put <language>.lng in the directory specified by this switch; if
-no dest_dir is given, output is the same as source_dir

 However, there is an even more noticable difference in rail station construction. You may now add platforms and lenght to a station after it has been built, and you may also add platforms of a different type. Users of TTDPatch will be used to this behaviour. But beyond what TTDPatch has, you can make stations of uneven lenght/width, and even ones with perpendicular tracks.

-Compiling OpenTTD using Microsoft Visual C++
-January 2, 2007
---------------------------------------------
-PLEASE READ THE ENTIRE DOCUMENT BEFORE DOING ANY ACTUAL CHANGES!!
-
-
-SUPPORTED MSVC COMPILERS
-------------------------
-OpenTTD includes projects for MSVC 2005.NET and MSVC 2008.NET. Both will
-compile out of the box, providing you have the required libraries/headers;
-which ones, see below. There is no support for VS6 or MSVC 2002, or
-MSVC 2003.NET. You are therefore strongly encouraged to either upgrade to
-MSVC 2005 Express (free) or use GCC.
-
-
-1) REQUIRED FILES
------------------
-You might already have some of the files already installed, so check before
-downloading; mostly because the DirectX SDK and Platform SDK are about
-500MB each.
-Download the following files:
-
-	* openttd-useful.zip (http://sf.net/project/showfiles.php?group_id=103924&package_id=114307)
-	* DirectX 8.1 SDK (http://neuron.tuke.sk/~mizanin/eng/Dx81sdk-include-lib.rar) (or alternatively the latest DirectX SDK from Microsoft)
-	* MS Windows Platform SDK (http://www.microsoft.com/downloads/details.aspx?FamilyId=A55B6B43-E24F-4EA3-A93E-40C0EC4F68E5&displaylang=en)
-	* afxres.h (http://www-d0.fnal.gov/d0dist/dist/packages/d0ve/devel/windows/AFXRES.H)
-
-...and of course the newest source from svn://svn.openttd.org/trunk
-
-You need an SVN-client to download the source from subversion:
-
-	* CLI Subversion (http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91)
-	* GUI TortoiseSVN (http://tortoisesvn.tigris.org/download.html)
-
-
-2) INCLUDES AND LIBRARIES
--------------------------
-Put the newly downloaded files in the VC lib\ and include\ directories; where
-"C:\Program Files\Microsoft Visual Studio 8\VC" is your location of Visual C.
-If you are compiling for an x64 system, use the include\ and lib\ directories
-from the win64/ folder.
-
-	* openttd-useful.zip\include\*
-	* afxresh.h
-	to >	C:\Program Files\Microsoft Visual Studio 8\VC\Include
-
-	* openttd-useful.zip\lib\*
-	to >	C:\Program Files\Microsoft Visual Studio 8\VC\Lib
-
-Custom directories might be recommended, check 2.2)
-
-
-2.1) INCLUDES AND LIBRARIES - DIRECTX/PLATFORM SDK
---------------------------------------------------
-Basically the same procedure as with the useful zip file, providing
-you are not using the Microsoft installer. Put the include files in the
-include\ directory and the library files to the Lib\ directory.
-
-It is recommended to use custom directories so you don't overwrite any
-default header or library files.
-
-
-2.2) CUSTOM DIRECTORIES
------------------------
-If you have put the above include and/or library files into custom folders,
-MSVC will not find them by default. You need to add these paths to VC through:
-
-Tools > Options > Projects and Solutions > VC++ Directories > show directories for
-
-	* Include files: Add the DirectX/Platform SDK include dir you've created
-	* Library files: Add the path to the SDK custom lib dir
-
-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!!
-
-
-3) TTD GRAPHICS FILES
----------------------
-Copy the following files from Transport Tycoon Deluxe to the bin/data folder
-
-	* sample.cat
-	* trg1r.grf
-	* trgcr.grf
-	* trghr.grf
-	* trgir.grf
-	* trgtr.grf
-
-
-4) COMPILING
-------------
-Open trunk/openttd_vs[89]0.sln
-Set the build mode to 'Release' in
-Build > Configuration manager > Active solution configuration > select "Release"
-Compile...
-
-If everything works well the binary should be in trunk/objs/Win[32|64]/Release/openttd.exe
-
-
-5) EDITING, CHANGING SOURCE CODE
---------------------------------
-Set the build mode (back to) 'Debug'
-Change the startup project to openttd by right-clicking the 'openttd' project
-in the Solution Explorer and selecting 'Set as Startup Project'. The 'openttd'
-project should now show up bold instead of 'strgen'.
-
-
-6) PROBLEMS?
-------------
-If compilation fails, double-check that you are using the latest SVN (!)
-source. If it still doesn't work, check in on IRC (irc://irc.oftc.net/openttd),
-to ask about reasons; or just wait. The problem will most likely solve itself
-within a few days as the problem is noticed and fixed.

+Compiling OpenTTD using Microsoft Visual C++ 6.0
+
+
+---Step 1
+
+Download the following files:
+
+    * Useful.zip (http://sourceforge.net/project/showfiles.php?group_id=103924&package_id=114307&release_id=228633)
+    * SDL-1.2.8-VC6.zip (http://www.libsdl.org/release/SDL-devel-1.2.8-VC6.zip)
+    * DirectX7.0 SDK (http://www.tt-forums.net/download.php?id=15989) (or alternatively the latest DirectX SDK from Microsoft)
+    * afxres.h (http://www-d0.fnal.gov/d0dist/dist/packages/d0ve/devel/windows/AFXRES.H) 
+
+...and of course the newest source from svn://svn.openttd.com/trunk
+
+(The alpha version of the new map array can be found at svn://svn.openttd.com/branch/map)
+
+You have to have and SVN-client to download the source:
+
+    * Command line version (http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91)
+    * TortoiseSVN (http://tortoisesvn.tigris.org/download.html) 
+
+
+---Step 2
+
+Put the newly downloaded files in the VC lib and include directories (Where C:\program files\ 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]
+    * SDL.lib [SDL.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.) 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.
+
+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, 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 7 SDK\include )
+
+b) library files (the lib dir, C:\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 
+
+
+---Step 5
+
+Open trunk/ttd.dsw
+
+Build menu > Set active configuration > Select: "ttd - Win32 Release with PNG"
+
+Compile...
+
+
+Now it should work, it worked for me :)
+
+From r1319 you can compile branch/map in Debug mode (by Bociusz)
+
+If it's not working, and you checked that you using the newest SVN (!) report to Bociusz on IRC (irc://irc.freenode.net/#openttd)
+
+Go ahead and make that patch! Happy Hacking! :)

+Notes about DirectMusic driver for Win32
+----------------------------------------
+
+If compiling under MinGW32, you require the DirectX 7.0 files for MinGW32, available from
+http://alleg.sourceforge.net/files/dx70_mgw.zip.
+
+If compiling under MSVC 6.0, you require the equivalent for MSVC, available from
+http://alleg.sourceforge.net/files/dx70_min.zip. MSVC 7.0/7.1 include header files that
+are recent enough.
+
+If you do not want to compile the DirectMusic driver, undefine WIN32_ENABLE_DIRECTMUSIC_SUPPORT
+in stdafx.h.

+- The volume control doesn't work properly. I'll fix this soon.

-<span style="font-weight: bold;"></span>Six attributes hold the information about a tile.
+<span style="font-weight: bold;"></span>Five arrays are used to encode the information of the contents of the tile.
 This can be seen in the <a href="landscape.html">Landscape</a> document. This page tries to give an overview of used and free bits of
 the array so you can quickly see what is used and what is not.
 <ul>
-  <li><span style="font-weight: bold;"><span class="free">O</span></span> - bit is free</li>
-  <li><span style="font-weight: bold;"><span class="used">X</span></span> - bit is used</li>
-  <li><span style="font-weight: bold;"><span class="abuse">&nbsp;</span></span> - bit of attribute is abused for different purposes, i.e. other bits define the actual meaning.</li>
-  <li><span style="font-weight: bold;"><span class="option">~</span></span> - bit is accessed, but does not really have a meaning (e.g. owner of clear land is always OWNER_NONE)</li>
+  <li><span style="font-weight: bold;"><span class="freebits">O</span></span> - bit is free</li>

 </ul>
 <p>
 <ul>
-  <li><span style="font-weight: bold;">type_height</span> - 8 bits in size, stores tile height (lower 4 bits) and tile class (upper 4 bits)</li>

-------------------

- - My advertised server does not show up in the 'advertised server list' (servers.openttd.org)
-     Run openttd with the '-d net=2' parameter, as this will show whether it receives replies from the master server.
-     If it does not receive replies it is most likely that you need to configure your router to forward the OpenTTD ports 3979 (both TCP and UDP) to the computer that is hosting the game.
