Description
-----------

sz81 is a port of Russell Marks's SVGAlib z81 Sinclair ZX80/81 emulator
to SDL with some additional functionality.

Features:
 * Virtual keyboard with adjustable opacity, autohide on newline,
   sticky shift or toggle shift
 * Control bar with access to several regularly used options
 * The ability to run centred within any resolution
 * Runtime switchable scaling up to 3x on supported platforms
 * Toggling between a window and fullscreen on supported platforms
 * Support for portrait orientated screens such as 240x320 and 480x640
 * User-definable (actually currently developer-definable) keys
 * Joystick to keyboard remapping (joystick navigation is to follow)
 * Maximum porting potential since it only requires SDL

Note that this includes the missing OSS_SOUND_SUPPORT directives which
I found independently even though there is a patch on the z81 website
http://www.svgalib.org/rus/z81.html that does a similar thing.
Therefore you needn't and shouldn't apply that patch.

To-Do:
 * Virtual keyboard navigation and activation using a joystick
 * Key repeating within the GUI
 * OSS to SDL API sound conversion

    Clicking the screen (or F1) brings up the virtual keyboard and the

    To access the file selector type "J", SHIFT + "P" twice and ENTER
    from within the emulator.
