-Project files for embedded Visual C++ 4.0 can be found in VisualCE.zip
+Project files for embedded Visual C++ 3.0, 4.0 and 
+Visual Studio 2005 can be found in VisualCE.zip
+
+SDL supports GAPI and WinDib output for Windows CE.
+
+GAPI driver supports:
+
+- all possible WinCE devices (Pocket PC, Smartphones, HPC)
+  with different orientations of video memory and resolutions.
+- 4, 8 and 16 bpp devices
+- special handling of 8bpp on 8bpp devices
+- VGA mode, you can even switch between VGA and GAPI in runtime
+  (between 240x320 and 480x640 for example). On VGA devices you can
+  use either GAPI or VGA.
+- Landscape mode and automatic rotation of buttons and stylus coordinates.
+  To enable landscape mode make width of video screen bigger than height.
+  For example: 
+    SDL_SetVideoMode(320,240,16,SDL_FULLSCREEN)
+- WM2005
+- SDL_ListModes
 
 NOTE:
 There are several SDL features not available in the WinCE port of SDL.
Binary file VisualCE.zip has changed
