WHAT IS DUMMY ADD?
------------------

   Dummy Add is a tool to automatically shift data in a CDRWIN bin file to
the outside of the CD.  The data is stored in an ISO file because the image
is smaller, compresses better, and is readily burnable by a large number of
programs.  There is no actual dummy file that is viewable on the CD, rather
the program simply adds a large number of unused sectors to the start of the
CD before the actual game data.

   There is also a CUE sheet created that can be used by users of CDRWIN to
burn the ISO directly.  I would recommend using CDRWIN to burn the generated
files, or if your drive isn't supported use Easy CD Creator and select the
"Create CD from CD Image" option from the File menu and point it to the ISO.  

   The most important feature of the program is that it maintains the correct
ordering of files as they appear on the GDROM.  When you manually create a
dummy file and extract the files using isobuster or winimage, you screw up
the file ordering (since it will now be alphabetical when you add it).  Using
this program ensures the files are in exactly the same sector order (LBA
addresses).  This stops the unnecessary seeking that generates a lot of heat
and is the likely cause of people frying their Dreamcast.  

   So far only Kalisto releases appear to include the correct ordering of
files as they appear on the GDROM (Utopia and Accession releases are sorted
alphabetically).  Ever wonder why Dead Or Alive 2 takes so long to load and
seeks endlessly?  This is because it has such a large number of small files
and they are fragmented all over the CD.  If you are concerned about rips
damaging your Dreamcast by over seeking, then I would stick to Kalisto
releases until the other groups get their act together.  


HOW TO USE DUMMY ADD
--------------------

   Dummy Add is a console application which means you must access it from
a DOS window.  Change into the directory containing the BIN file and DummyAdd
and you can then convert the file.  To convert a file such as SONIC.BIN into
an ISO named NEWSONIC.ISO, all you would have to type is:

        da sonic newsonic

   You will then be prompted for a padding option.  Press 0 for no padding
which won't add any dummy sectors (essentially a bin2iso conversion).  Press
1 to pad the file to fit on a 74 min CD, and press 2 to make it fit an 
80 min CD.   After the selection the program will work away until you have
an ISO ready to burn.  It will take a few minutes to convert the file, and
remember you must have 650-700MEG free for the output ISO to be written.
