 Based on version 0.9.4a
 Emulator Core by Charles Mac Donald
 SDL Version by Gregory Montoir (cyx@frenchkiss.net)

 
 [What is it]

 SMS Plus is Sega Master System and Game Gear emulator. Originally,
 it was written to run under DOS. Since Charles Mac Donald released
 his emulator under the GPL terms, this emulator has been ported to
 different platforms (Windows, BeOS... refer to Charles' website
 to have the complete list). 
 Because I wanted to play with the SDL library and emulators, I began
 to write a SDL version of this emulator.
 If you want to have technical information about the emulation engine,
 refer to the original 'README.TXT', since I made no changes to the 
 emulation core. I only 'ported' it to SDL compliant platforms.
 I won't explain you how to run it, if you know what emulation is, you
 should be able to help yourself.


 [Features]

 - Emulation of Game Gear and Master System
 - Slots for saving/loading
 - Sound
 - Frameskip option for slow machines
 - Filtered rendering for fast machines


 [Hotkeys]

 F1:    screenshot in BMP format
 F2:    save state
 F3:    load state
 F4/F5: dec/inc frame skip value
 F6/F7: dec/inc state slot
 1..8:  switch rendering filter
 C:     button 1
 V:     button 2
 ENTER: start (GG) / pause (SMS)
 ARROW: directional pad
 TAB:   console hard reset


 [Compiling]

 You need SDL-1.2.X (maybe older versions will be fine), and a C compiler. 
 For the moment, I only tested GCC and Microsoft Visual C++ 6.

 GCC (MinGW seems ok, also): 
 A makefile is provided. Just cd to sdl/, type make and cross your fingers.
  
 Visual C++:
 Open the workspace sms_sdl.dsw. Enter the path to the SDL include files 
 in Tools|Options|Directories. Now it should compile.
