!Multi - Multisync sprite display.   1991 Alun Jones.

This application will display sprites from any mode
from 0-28 except 23, and of any size from little icons
to great big 800x592 or 960x512 pictures, on a
standard non multisync monitor. Sprites bigger than
this will simply have their right and bottom edges cut
off. As Multi only needs 16K of memory it can be kept
loaded even on a 1Mb machine.

To use simply drag a sprite file to its icon. The
sprite(s) will then be loaded and displayed, using
interlace to emulate the high resolution of multisync
and (super) VGA sprites if needed. Left button or
Shift steps through the sprites in a file, while
middle button or Space return you to the desktop.

When using interlace press the right mouse button or
RETURN once or twice for best display results. This is
needed as I don't know how to check the current
interlace position, which means I can't automatically
align the picture to it.

Control summary
---------------

Left click on the Multi icon reloads the last picture,
so your favourite piccy is only a mouse click away.

While the picture is displayed:

  Mouse button     Keyboard         Action

     Left           Shift        Step through sprites
     Middle         Space        Return to desktop
     Right          Return       Re-align interlace

HiRes
-----

The 'HiRes' option on the iconbar menu gives access to
a 960x256 mode with 256 colours, which is interlaced
to 960x512. I find this most useful for displaying GIF
pictures that have been scaled up using Translator by
3:2 in the X direction. This gives more pixels for
dithering, often resulting in a better colour match.
Note that when HiRes is ticked ALL sprites will be
displayed in this mode, regardless of their original
mode, so be prepared for odd colours and aspect ratios
if used inappropriately.

Modules
-------

Multi uses two new modes, 80 and 81, created with
ModeDef by Nick Jarman (interlace in brackets) :

  Mode      Resolution      Colours      Memory
   80      800x296 (592)      256      232K (464)
   81      960x256 (512)      256      240K (480)

If these mode numbers clash with some you already use
then open up Multi's directory and run !Change. This
will prompt you for new numbers for modes 80 and 81.
It will then change and rename the mode modules and
save the new numbers. If you get the modes in a mess
then delete the ModeNums file and run !Change giving
it the numbers of the mode modules FILE names. Then
re-run !Change and give it the numbers you really
want. This should get things going again (I hope!).

Multi also uses the DoubleMode module. This provides
one command to claim double the screen memory normally
used by a mode.
