Final release of our contribution
to the Silly Venture Atari Party!


Thanks to Leonard for sending me the
data file of the Nostalgic-O Atari ST
intro screen.

Note that this is a V1 version of the
ST-NICCC renderer. V1 differs little
bit but you get it when you have a
look at the provided 6502 code...

Fixed palette, no indexed mode, frame
end and file end have differently
encoded markers $fe and $ff compared
to V2. So should be easy to adapt
your ST-NICCC engines for the file.

The original version of the demo
was a cartridge-only release with
VBXE fixed at $d600. I have reworked
that version to include automatic
detection of the VBXE board and base
address ($d600 or $d700). The pack
contains the DOS compatible version
which support PORTB memory expansions
of 512 KB or more.
