Xworld - Another World interpreter for Rockbox

Co-conspirators: Franklin Wei, Benjamin Brown

--------------------------------------------------------------------
This work is based on:
- Fabien Sanglard's "Fabother World" based on
- Piotr Padkowski's newRaw interpreter which was based on
- Gregory Montoir's reverse engineering of
- Eric Chahi's assembly code

--------------------------------------------------------------------
Progress:

* The plugin runs pretty nicely (with sound!) on most color targets
* Keymaps for color LCD targets are complete
* The manual entry is finished
* Grayscale/monochrome support is NOT PLANNED
  - the game looks horrible in grayscale! :p

--------------------------------------------------------------------
Notes:

* The original game strings were built-in to the executable, and
  were copyrighted and could not be used.
* This port ships with an alternate set of strings by default, but
  can load the "official" strings from a file at runtime.

--------------------------------------------------------------------
To be done (in descending order of importance):

* vertical stride compatibility                          <30% done>
* optimization                                           <10% done>

+=================================================================================
+
+This is "Fabother World": an Another World (Out Of This World in North America) interpreter codebase. This work is based on:
+
+- Piotr Padkowski's newRaw interpreter which was based on
+- Gregory Montoir's reverse engineering of
+- Eric Chahi's assembly code.
+
+I cleaned up a lot of the code, removing cryptic hexadecimal notation
+with meaningful macros name. I also cleanup a lot of the code so it has a 
+C/C++ philosophy instead of an assembly structure.
+
+I also created a Visual Studio 2010 project.
+
+TODO:
+
+Create a MacOS X project.
+Add a different rendering path OpenGL support.

+About:
+------
+
+raw is a re-implementation of the engine used in the game Another World. This 
+game, released under the name Out Of This World in non-European countries, was

+found here : http://www.mobygames.com/game/sheet/p,2/gameId,564/.
+
+Please be aware that, currently, this implementation may contains bugs and 
+non-implemented features that make it impossible to finish the game.
