FullScreen
	- SDLHi renderer with fullscreen in config file can boot.
	  But very slow.(screen flickering sometimes.)
	- SDLLo renderer with fullscreen in config file can boot.
	  But slow.(screen flickering sometimes.)
	  Relatively better than SDLHi?
	- "fullscreen" command on console doesn't work.
	So currently windowed mode is recommended.



JoyPad or Mouse
	To use JoyPad or Mouse, do on console,
		plug joyporta joystick1
	or
		plug joyporta mouse
	"joyportb" if you want connent to port-B.
	If you have N JoyPads connented to PC,
	joystick2, ... joystickN will be avail.
	Don't use "AutoCommands" to plug JoyPad or Mouse for a while.
	If you do, you may face to troubles. (At least I faced...)



SDLGL renderer
	Some extended features are implemented on SDLGL renderer.
	But not tested well on UOW32.
	If you try, do on the console,
		renderer SDLGL
	and do on the console to back SDLHi renderer,
		renderer SDLHi

	Currently, start with SDLGL will cause MSX freeze.
	(openmsx.exe is alive still, so you can exit with F12.)
	Temporarily, you can workaround to start with SDLGL using following:
  <config id="renderer">
    <type>SDLHi</type>
    <parameter name="full_screen">false</parameter>
  </config>
  <config id="AutoCommands">
    <parameter>renderer SDLGL</parameter>
  </config>

	Don't use SDLGL renderer with fullscreen.
	It cause trouble. I faced.
