    I) Introduction :
    =-=-=-=-=-=-=-=-=

    Past-O-Rama is a free Windows9X/DirectX based emulator for the
    Sega SG1000 system. It requires at least DirectX 5.0

    For now, it's not really optimized, because it's nearly my first
    "serious" C program. I've started this because i'd like to improve my
    C skills and to learn a bit more about the emulation process.

    II) Hey, how does it works ?
    =-=-=-=-=-=-=-=-=-=-=-=-=-=

    Nearly simply, start the emulator itself or, passing the name and path of 
    a ROM to start up with.

    Menu description :
    ------------------

    File    ->  Load rom    : do i have to explain something ?
            ->  Free rom    :
            ->  Quit

    Machine ->  Pause       : works like the Pause button present on the real SG1000
            ->  Reset       : Does a hardware reset

    Video   ->  Fullscreen  : toggle fullscreen (320x200x16)/windowed mode
                RGB mode    : depend on your video card (565 is the default)
                              if you have strange color, switch here to 555.                                                                             
                Size x 1    :-\
                Size x 2    :  |-> scale the window (2x is default)
                Size x 3    :-/
                Strech      : in fullscreen mode, strech the screen to
                              the whole display area.


    Keys :
    ------

    For now, Past-O-Rama only emulate the player 1 joypad, and the keys are
    not redifinable but there's support for both the keyboard and joystick :

    LEFT SHIFT or joystick B1          :   BUTTON 1   
    LEFT CTRL  or joystick B2          :   BUTTON 2
    Up/Down/Left/Right                 :   directional pad
    

    ALT-ENTER    : toggle fullscreen/windowed mode
    TAB          : does a hard reset


    III) Know issues :
    =-=-=-=-=-=-=-=-=-

    PAST-O-RAMA WILL ONLY RUNS IN 15/16 BPP !!!!!
    
    The emulation is not perfect, but the compatibily is quite high.
    For the few roms that i've tried (+-40), i get only troubles with :

    Yamato          ( slowdown : bad interrupt handling )
    Exerion         ( slowdown : bad interrupt handling )
    Rock'n Bolt     ( sprites priority but playable )
    Safari hunting  ( crash )

    Sometimes, the directsound buffer might be corrupted, just move a few
    the window and it'll fix this.


    IV) What about the future ?
    =-=-=-=-=-=-=-=-=-=-=-=-=-=

    I don't really know, there's lots of features that i'd like to add in
    this release but i was already in my pyjama ;)

    A total rewrite is planed before the next version.
