       dMagnetic  is  a  Magnetic  Scrolls  Interpreter.  To  actually play the games, their binaries have to be
       provided. Either in the .mag and .gfx format from https://msmemorial.if-legends.org/magnetic.php, as  the
       name of the directory in which the original MS-DOS version can be found, the location and the name of the
       second  resource  file  TWO.RSC,  as  D64-images  from  the Commodore 64 releases, as DSK-images from the
       Amstrad/Schneider CPC releases, as DSK-images from the Spectrum releases, as ADF/ADL/ADFS images from the
       Acorn Archimedes releases, as ATR images from the  AtariXL/Atari800  releases,  or  even  as  NIB/2MG/WOZ
       images from the Apple II releases.

       An  alternative  way to provide the location of the .mag and .gfx, the image files or the directory name,
       is through a dMagnetic.ini file. See helpini or dMagneticini(5) for an example of a working dMagnetic.ini
       file.
       IT SHOULD BE NOTED that the default location for dMagnetic.ini is in the user's home  directory.  If  the
       file is located there, "The Pawn", for example, can be started by typing
       dMagnetic pawn

       [-rmodepseudo] [-rseedSEED]
       [-rmodereal]
       Certain  elements  of  the game rely on chance. For this, the virtual machine within dMagnetic offers two
       possibilities: Playing against a "pseudo"  random  generator,  which  results  in  a  certain  degree  of
       determinism. On the other hand, playing with "real" random values from the operating system, allows for a
       completely new experience.

       [-savegamesadvanced]
       [-savegamesclassic]
       Saving and restoring game states is a major part of playing interactive fiction.  dMagnetic is capable of
       loading  the  "classic" formats, to allow players to continue their 30 year old game. However, it prefers
       the "advanced" format, which is more robust.

       [-vrowsROWS]
       [-vcolsCOLUMNS]
       dMagnetic has been designed with terminal windows as main output in mind. The terminal window has a fixed
       number of rows and columns to print out text. Its size is limited, but it is used by dMagnetic to  render
       the  beautiful  BEAUTIFUL pictures as well. To restrict the space in which they are rendered (in glorious
       ANSI art), those options can be used to set the upper limits.

       [-vecho]
       When trying to run dMagnetic and redirecting the output into a file, the inputs are missing. This  option
       reprints what was typed in, to allow for a spoilery script.

       [-vlogLOGFILE.log]
       Sort of a travel journal, this option lets you write the commands that where typed into a file.

       [-vmodenone]
       [-vmodemonochrome]
       [-vmodelow_ansi]
       [-vmodelow_ansi2]
       [-vmodehigh_ansi]
       [-vmodehigh_ansi2]
       [-vmodeutf]
       [-vmodesixel] [-sres1024x768] [-sforce]
       This option allows for selecting a different mode to render the images, should the actual one prove to be
       unsuitable for the preferred terminal program.

       [-version]
       Shows the current version of dMagnetic

Description

dMagnetic is an interpreter for classic text adventure games, or interactive fiction, such as "The  Pawn"
       and "The Guild of Thieves". The following games are being supported:

Game Binaries

       Currently,   binaries   in   the   .mag   and   .gfx   format  from  the  magnetic  scrolls  memorial  at
       https://msmemorial.if-legends.org/memorial.php are being supported.  Once downloaded, their position  has
       to be made available to dMagnetic by editing dMagnetic.ini first.
       Other possibilities are loading the games from original releases, such as

       the MS-DOS binaries

       the Magnetic Windows Resource Files

       the Commodore C64 images in the d64 format

       Amstrad CPC and Spectrum128 images in the DSK format

       Acorn Archimedes images in the ADF/ADL (aka ADFS) format

       AtariXL/Atari800 images in the ATR format

       Apple II images in the 2MG, NIB or WOZ format

Graphic Modes

dMagnetic  has  been  developed with ANSI-consoles in mind. To select a video output that best suits your
       needs, please try one of the following

       dMagnetic [-iniini-file] [GAME] [-vmodenone]
       dMagnetic [-iniini-file] [GAME] [-vmodemonochrome]
       dMagnetic [-iniini-file] [GAME] [-vmodemonochrome_inv]
       dMagnetic [-iniini-file] [GAME] [-vmodelow_ansi]
       dMagnetic [-iniini-file] [GAME] [-vmodelow_ansi2]
       dMagnetic [-iniini-file] [GAME] [-vmodehigh_ansi]
       dMagnetic [-iniini-file] [GAME] [-vmodehigh_ansi2]
       dMagnetic [-iniini-file] [GAME] [-vmodeutf]

       To change the number of rows/columns to render the images, use

       dMagnetic [-iniini-file] [GAME] [-vcolsCOLUMNS]
       dMagnetic [-iniini-file] [GAME] [-vrowsROWS]

       Sixels are a signalling mode for some terminal emulators (like mlterm, or xterm -ti vt340 , for example),
       that offer the possibility of drawing high resolution images. It can be selected with

       dMagnetic [-iniini-file] [GAME] [-vmodesixel] [-sres1024x768] [-sforce]

       where the -sres option offers a way to scale the images.  The  maximum  allowed  width  is  4096  pixels.
       Instead  of  automatically  using  a  matching  aspect ratio, the -sforce option can be used to force the
       resolution.

Graphics In Wonderland And The Magnetic Scrolls Collection

       Before you can see the beautiful graphics in "Wonderland", or from the Magnetic Scrolls  Collection,  you
       have to type in "graphics" to enable them.

Introduction

       You  wake  up  on  a  sunny August morning with birds singing, and the air fresh and clear. However, your
       joints are stiff and you have not woken up in your bedroom as you would have expected. Trying  to  recall
       what  happened  the night before, you manage to piece together a few brief glimpses to give the following
       account...

Leaving The Game

       Type in "QUIT". Duh!

Name

       dMagnetic — A Magnetic Scrolls Interpreter

Saving/Loading Progress

       The game can be saved at any type by typing SAVE, and loaded by typing LOAD. Followed by a filename.

       SAVE myprogress1.sav
       LOAD myprogress1.sav

Starting The Game

Once the game(s) have been downloaded, the .mag and .gfx files can be provided via

dMagnetic -mag pawn.mag -gfx pawn.gfx

Alternatively, binaries from the MSDOS version of "The Pawn" or "The Guild of Thieves" can be used. The
directory, in which they are, has to be provided via

dMagnetic -msdosdir DIRECTORY/ -vmode high_ansi

It is recommended to use the [-vmodehigh_ansi2] option, since this renders the half-tone images slightly
different.

A third option is to use the resource files from "Wonderland" or the magnetic scrolls collection. For
this, the location of the file ending with "TWO.RSC" has to be provided.

dMagnetic -tworsc DIRECTORY/TWO.RSC -vmode high_ansi
dMagnetic -tworsc DIRECTORY/GTWO.RSC -vmode high_ansi -ega
The names of the other resource files is being calculated from that. With the optional parameter -ega,
the EGA versions of the pictures are being shown.

A fourth option is to use D64 image files from the Commodore 64 releases. They come in pairs, since both
sides of the floppy disk were occupied. So the parameter requires a list of them, separated by komma:

dMagnetic -d64 DIRECTORY/FILE1.d64,DIRECTORY/FILE2.d64 -vmode sixel

A fifth option is to use DSK image files from the Amstrad CPC releases. They come in pairs, since noth
sides of the floppy disk were occupied. So the parameter requires a list of them, separated by komma:

dMagnetic -amstradcpc DIRECTORY/FILE1.DSK,DIRECTORY/FILE2.DSK -vmode sixel

A sixth option is to use DSK image files from the Spectrum releases. Since this platform did not have the
pictures, a single floppy disk was enough:

dMagnetic -spectrum DIRECTORY/DISKIMAGE.DSK -vmode none

A seventh option is to use ADF/ADL/ADFS image files from the Acorn Archimedes releases.

dMagnetic -archimedes DIRECTORY/DISKIMAGE.ADF

An eigth option is to use ATR image files from the AtariXL/Atari800 releases. Those come in pairs.

dMagnetic -atarixl DIRECTORY/FILE1.ATR,DIRECTORY/FILE2.ATR

An ninth option is to use image files from the Apple II releases. dMagnetic can handle NIB, 2MG and WOZ.
For this platform, up to three disks were used, so three floppy images are required.

dMagnetic -appleii 1.NIB,2.NIB,3.NIB
dMagnetic -appleii 1.2MG,2.2MG,3.2MG
dMagnetic -appleii 1.WOZ,2.WOZ,3.WOZ

It is also possible to edit the dMagnetic.ini file and start a specific game, by using one of

dMagnetic -ini dMagnetic.ini pawn
dMagnetic -ini dMagnetic.ini guild
dMagnetic -ini dMagnetic.ini jinxter
dMagnetic -ini dMagnetic.ini corruption
dMagnetic -ini dMagnetic.ini fish
dMagnetic -ini dMagnetic.ini myth
dMagnetic -ini dMagnetic.ini wonderland

When you see the prompt, the game is ready to accept your commands. For example EXAMINE CLOTHES. Or GO
EAST. Or ASK KRONOS ABOUT THE WRISTBAND.
