+
+A port of DOSBox to the Wii using SDL Wii.
+
+-=[ Features ]=-
+
+* USB Keyboard and mouse support
+* Wiimote pointer support
+* SD/USB mounting
+* Most DOS games are playable
+
+-=[ Update History ]=-
+
+[1.0 - October 9, 2009]
+
+* Home menu and on-screen keyboard (a proof of concept showing SDL + libwiigui)
+* Small speed increases via SDL Wii improvements
+* Compiled with devkitPPC r18 and libogc 1.8.0
+* Updated to latest DOSBox SVN
+
+[0.73.02 - July 1, 2009]
+
+* Upgraded DOSBox engine to latest SVN 
+* Fixed lockup when only using the Wiimote (no attachments connected) 
+* Compiled with latest libogc and SDL Wii 
+
+[0.73.01 - June 3, 2009]
+
+* Upgraded DOSBox engine to 0.73 
+* Sound issues fixed 
+* Compiled with latest libogc and SDL Wii 
+
+[0.72.01 - May 14, 2009]
+
+* Initial release
+
+-=[ Instructions ]=-
+
+You need a Wii Remote and a USB keyboard. The C: drive will automatically be
+mounted to sd:/DOSBox/ if loaded from apps/dosbox-wii/. Otherwise, the 
+directory the dol is loaded from will be mounted as C, and sd:/DOSBox as D 
+(if present). The Z: driver is a virtual drive that is part of DOSBox. 
+
+Other drives can be mounted using the MOUNT command. Prefix sd: for an SD card,
+and usb: for a USB drive. The Wii's DVD drive and network folders can't be 
+mounted at this time. 
+
+The configuration file is loaded from the directory the dol is located in 
+(if present) and sd:/DOSBox/dosbox.conf otherwise. This file will be created 
+automatically after you start DOSBox. Please edit it with a text editor 
+to choose settings appropriate for each game. 
+
+Press the Home button, type "exit", press Ctrl+F9, or press Reset (on the 
+console) to exit. 
+
+-=[ Compatibility ]=-
+
+Most games work properly now; however, many games will require some sort 
+of adjustment to the dosbox.conf file. It is recommended to try the game 
+you want to play on the PC version of DOSBox first to discover the optimum 
+settings.

+/** \mainpage FreeTypeGX
+ *
+ * \section sec_intro Introduction
+ *
+ * FreeTypeGX is a wrapper class for libFreeType which renders a compiled FreeType parsable font into a GX texture for Wii homebrew development.
+ * <br>
+ * FreeTypeGX is written in C++ and makes use of a selectable pre-buffered or buffer-on-demand methodology to allow fast and efficient printing of text to the EFB.
+ * <p>
+ * This library was developed in-full by Armin Tamzarian with the support of developers in \#wiibrew on EFnet.
+ *
+ * \section sec_installation_source Installation (Source Code)
+ *
+ * -# Ensure that you have the <a href = "http://www.tehskeen.com/forums/showthread.php?t=9404">libFreeType</a> Wii library installed in your development environment with the library added to your Makefile where appropriate.
+ * -# Ensure that you have the <a href = "http://code.google.com/p/metaphrasis">Metaphrasis</a> library installed in your development environment with the library added to your Makefile where appropriate.
+ * -# Extract the FreeTypeGX archive.
+ * -# Copy the contents of the <i>src</i> directory into your project's development path.
+ * -# Include the FreeTypeGX header file in your code using syntax such as the following:
+ * \code
+ * #include "FreeTypeGX.h"
+ * \endcode
+ *
+ * \section sec_installation_library Installation (Library)
+ *
+ * -# Ensure that you have the <a href = "http://www.tehskeen.com/forums/showthread.php?t=9404">libFreeType</a> Wii library installed in your development environment with the library added to your Makefile where appropriate.
+ * -# Ensure that you have the <a href = "http://code.google.com/p/metaphrasis">Metaphrasis</a> library installed in your development environment with the library added to your Makefile where appropriate.
+ * -# Extract the FreeTypeGX archive.
+ * -# Copy the contents of the <i>lib</i> directory into your <i>devKitPro/libogc</i> directory.
+ * -# Include the FreeTypeGX header file in your code using syntax such as the following:
+ * \code
+ * #include "FreeTypeGX.h"
+ * \endcode
+ *
+ * \section sec_freetypegx_prerequisites FreeTypeGX Prerequisites
+ *
+ * Before you begin using FreeTypeGX in your project you must ensure that the desired font in compiled into your project. For this example I will assume you are building your project with a Makefile using devKitPro evironment and are attempting to include a font whose filename is rursus_compact_mono.ttf.
+ *
+ * -# Copy the font into a directory which will be processed by the project's Makefile. If you are unsure about where you should place your font just copy the it into your project's source directory.
+ * \n\n
+ * -# Modify the Makefile to convert the font into an object file:
+ * \code
+ * %.ttf.o : %.ttf
+ * 	@echo $(notdir $<)
+ * 	$(bin2o)
+ * \endcode
+ * \n
+ * -# Include the font object's generated header file in your source code:
+ * \code
+ * #include "rursus_compact_mono_ttf.h"
+ * \endcode
+ * This header file defines the two variables that you will need for use within your project:
+ * \code
+ * extern const u8 rursus_compact_mono_ttf[];	A pointer to the font buffer within the compiled project.
+ * extern const u32 rursus_compact_mono_ttf_size;	The size of the font's buffer in bytes.
+ * \endcode
+ *
+ * \section sec_freetypegx_usage FreeTypeGX Usage
+ *
+ * -# Within the file you included the FreeTypeGX.h header create an instance object of the FreeTypeGX class:
+ * \code
+ * FreeTypeGX *freeTypeGX = new FreeTypeGX();
+ * \endcode
+ * Alternately you can specify a texture format to which you would like to render the font characters. Note that the default value for this parameter is GX_TF_RGBA8.
+ * \code
+ * FreeTypeGX *freeTypeGX = new FreeTypeGX(GX_TF_RGB565);
+ * \endcode
+ * Furthermore, you can also specify a vertex format index to avoid conflicts with concurrent libraries or other systems. Note that the default value for this parameter is GX_VTXFMT1.
+ * \code
+ * FreeTypeGX *freeTypeGX = new FreeTypeGX(GX_TF_RGB565, GX_VTXFMT1);
+ * \endcode
+ * \n
+ * Currently supported textures are:
+ * \li <i>GX_TF_I4</i>
+ * \li <i>GX_TF_I8</i>
+ * \li <i>GX_TF_IA4</i>
+ * \li <i>GX_TF_IA8</i>
+ * \li <i>GX_TF_RGB565</i>
+ * \li <i>GX_TF_RGB5A3</i>
+ * \li <i>GX_TF_RGBA8</i>
+ *
+ * \n
+ * -# Using the allocated FreeTypeGX instance object call the loadFont function to load the font from the compiled buffer and specify the desired point size. Note that this function can be called multiple times to load a new:
+ * \code
+ * freeTypeGX->loadFont(rursus_compact_mono_ttf, rursus_compact_mono_ttf_size, 64);
+ * \endcode
+ * Alternately you can specify a flag which will load and cache all available font glyphs immidiately. Note that on large font sets enabling this feature could take a significant amount of time.
+ * \code
+ * freeTypeGX->loadFont(rursus_compact_mono_ttf, rursus_compact_mono_ttf_size, 64, true);
+ * \endcode
+ * \n
+ * -# If necessary you can enable compatibility modes with concurrent libraries or systems. For more information on this feature see the documentation for setCompatibilityMode:
+ * \code
+ * freeTypeGX->setCompatibilityMode(FTGX_COMPATIBILITY_GRRLIB);
+ * \endcode
+ * -# Using the allocated FreeTypeGX instance object call the drawText function to print a string at the specified screen X and Y coordinates to the current EFB:
+ * \code
+ * freeTypeGX->drawText(10, 25, _TEXT("FreeTypeGX Rocks!"));
+ * \endcode
+ * Alternately you can specify a <i>GXColor</i> object you would like to apply to the printed characters:
+ * \code
+ * freeTypeGX->drawText(10, 25, _TEXT("FreeTypeGX Rocks!"),
+ *                      (GXColor){0xff, 0xee, 0xaa, 0xff});
+ * \endcode
+ * Furthermore you can also specify a group of styling parameters which will modify the positioning or style of the text:
+ * \code
+ * freeTypeGX->drawText(10, 25, _TEXT("FreeTypeGX Rocks!"),
+ *                      (GXColor){0xff, 0xee, 0xaa, 0xff},
+ *                      FTGX_JUSTIFY_CENTER | FTGX_ALIGN_BOTTOM | FTGX_STYLE_UNDERLINE);
+ * \endcode
+ * \n
+ * Currently style parameters are:
+ * \li <i>FTGX_JUSTIFY_LEFT</i>
+ * \li <i>FTGX_JUSTIFY_CENTER</i>
+ * \li <i>FTGX_JUSTIFY_RIGHT</i>
+ * \li <i>FTGX_ALIGN_TOP</i>
+ * \li <i>FTGX_ALIGN_MIDDLE</i>
+ * \li <i>FTGX_ALIGN_BOTTOM</i>
+ * \li <i>FTGX_STYLE_UNDERLINE</i>
+ * \li <i>FTGX_STYLE_STRIKE</i>

+ * \section sec_intro Introduction
+ * 
+ * Metaphrasis is a static conversion class for transforming RGBA image buffers into verious GX texture formats for Wii homebrew development.
+ * <br>
+ * Metaphrasis is written in C++ and makes use of a community standard and newly developed algorithms for conversion of 32-bit RGBA data buffers into various GX texture formats common to both the Gamecube and Wii platforms.  
+ * <p>
+ * This library was developed in-full by Armin Tamzarian with the support of developers in \#wiibrew on EFnet, Chaosteil of libwiisprite, and DrTwox of GRRLIB. 
+ * 
+ * \section sec_installation_source Installation (Source Code)
+ * 
+ * -# Extract the Metaphrasis archive.
+ * -# Copy the contents of the <i>src</i> directory into your project's development path.
+ * -# Include the Metaphrasis header file in your code using syntax such as the following:
+ * \code
+ * #include "Metaphrasis.h"
+ * \endcode
+ * 
+ * \section sec_installation_library Installation (Library)
+ * 
+ * -# Extract the Metaphrasis archive.
+ * -# Copy the contents of the <i>lib</i> directory into your <i>devKitPro/libogc</i> directory.
+ * -# Include the Metaphrasis header file in your code using syntax such as the following:
+ * \code
+ * #include "Metaphrasis.h"
+ * \endcode
+ * 
+ * \section sec_usage Usage
+ * 
+ * -# Create a buffer full of 32-bit RGBA values noting both the pixel height and width of the buffer.
+ * -# Call one of the many conversion routines from within your code. (Note: All methods within the Metaphrasis class are static and thus no class instance need be allocated)
+ * \code
+ * uint32_t* rgba8Buffer = Metaphrasis::convertBufferToRGBA8(rgbaBuffer, bufferWidth, bufferHeight);
+ * \endcode
+ * -# Free your temporary RGBA value buffer if you no longer need said values.
+ * 
+ * Currently supported conversion routines are as follows:
+ * \li convertBufferToI4
+ * \li convertBufferToI8
+ * \li convertBufferToIA4
+ * \li convertBufferToIA8
+ * \li convertBufferToRGBA8
+ * \li convertBufferToRGB565

+/*!\mainpage libwiigui Documentation
+ *
+ * \section Introduction
+ * libwiigui is a GUI library for the Wii, created to help structure the
+ * design of a complicated GUI interface, and to enable an author to create
+ * a sophisticated, feature-rich GUI. It was originally conceived and written
+ * after I started to design a GUI for Snes9x GX, and found libwiisprite and
+ * GRRLIB inadequate for the purpose. It uses GX for drawing, and makes use
+ * of PNGU for displaying images and FreeTypeGX for text. It was designed to
+ * be flexible and is easy to modify - don't be afraid to change the way it
+ * works or expand it to suit your GUI's purposes! If you do, and you think
+ * your changes might benefit others, please share them so they might be
+ * added to the project!
+ *
+ * \section Quickstart
+ * Start from the supplied template example. For more advanced uses, see the
+ * source code for Snes9x GX, FCE Ultra GX, and Visual Boy Advance GX.
+
+ * \section Contact
+ * If you have any suggestions for the library or documentation, or want to
+ * contribute, please visit the libwiigui website:
+ * http://code.google.com/p/libwiigui/
+
+ * \section Credits
+ * This library was wholly designed and written by Tantric. Thanks to the
+ * authors of PNGU and FreeTypeGX, of which this library makes use. Thanks
+ * also to the authors of GRRLIB and libwiisprite for laying the foundations.
