+/****** Interface Declaration ***********************************************/
+
+/*
+ *      These are macros for declaring interfaces.  They exist so that
+ *      a single definition of the interface is simulataneously a proper
+ *      declaration of the interface structures (C++ abstract classes)
+ *      for both C and C++.
+ *
+ *      DECLARE_INTERFACE(iface) is used to declare an interface that does
+ *      not derive from a base interface.
+ *      DECLARE_INTERFACE_(iface, baseiface) is used to declare an interface
+ *      that does derive from a base interface.
+ *
+ *      By default if the source file has a .c extension the C version of
+ *      the interface declaratations will be expanded; if it has a .cpp
+ *      extension the C++ version will be expanded. if you want to force
+ *      the C version expansion even though the source file has a .cpp
+ *      extension, then define the macro "CINTERFACE".
+ *      eg.     cl -DCINTERFACE file.cpp
+ *
+ *
+ *      Example C expansion:
+ *
+ *          typedef struct IClassFactory

@@ -7,26 +7,38 @@ SSNES is a simple frontend for the libsnes library.
 libsnes is the emulator core of [bSNES](http://www.byuu.org), the most accurate SNES emulator to date, in library form. The libsnes API has been implemented by SNES9x as well, allowing multiple different cores to be used for an emulator that supports libsnes.
 This enables the possibility of custom front-ends for the emulator.
 
+# Binaries
+
+Latest Windows binaries are currently hosted on my [homepage](http://themaister.net/ssnes.html).
+
 # Philosophy
 
 SSNES attempts to be very small and lean, while still having all the useful core features expected from an emulator. 
 It is used through command-line.
 
+# Platforms
+
+SSNES has been ported to the following platforms :
+
+   - PlayStation3
+   - Xbox 360 (Libxenon/XeXDK)
+   - Wii (Libogc)
+
 # Dependencies
 
 SSNES requires these libraries to build:
 
    - [libsnes](http://byuu.org/bsnes/)
    - SDL
-   - libsamplerate
 
 SSNES can utilize these libraries if enabled:
 
    - nvidia-cg-toolkit
    - libxml2 (bSNES XML shaders)
    - libfreetype2 (TTF font rendering on screen)
+   - libsamplerate
