 special, 'RIA' version

Despite this is ST floppy image format, it works not
from floppies.
RIA is Raw Image Access, special TOS extension,
what allows simple and fast access to mass storage,
so hard disk, Flash card, from games too. If game is
with direct floppy controller access, so not via TOS
functions for that, it needs some modifications.
This is case here. Floppy access code is redirected
to hard disk access. But it does not need extra RAM
as is usual. This version works with only 512KB in
Atari.

And as side effect of my effort, it even plays intro
music with only 512KB RAM, unlike original from
floppy. 
That's because I wanted that people with only 512KB
RAM can hear this great intro music, so planned to change
intro code, so, that load music in low RAM (instead over 512KB),
and disable graphical intro during it. But it happened that works
even together with graphic. I wonder how coder of game, who
is for sure good coder miscalculated RAM needs for this ...
It needed some 30 changes in code, mostly addresses, btw.

This is only teaser. You can not run this without modded TOS.
Availability of it will be announced on site when all is ready.
