NAME

dMagnetic
A Magnetic Scrolls Interpreter

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...

DESCRIPTION

dMagnetic is an interpreter for classic text adventure games, or interactive fiction, such as "The Pawn" or "The Guild of Thieves". The following games are being supported:
The Pawn
 
The Guild of Thieves
 
Jinxter
 
Fish!
 
Myth
 
Corruption
 
Wonderland
 

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.

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 [-vmode high_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 noth 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

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.

LEAVING THE GAME

Type in "QUIT". Duh!

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

TEXT ALIGNMENT

Changing the alignment of the output text can be done with the .ini file or the commandline.
dMagnetic -valign left
dMagnetic -valign block
dMagnetic -valign right

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 [-ini ini-file] [GAME] [-vmode none]
dMagnetic [-ini ini-file] [GAME] [-vmode monochrome]
dMagnetic [-ini ini-file] [GAME] [-vmode low_ansi]
dMagnetic [-ini ini-file] [GAME] [-vmode low_ansi2]
dMagnetic [-ini ini-file] [GAME] [-vmode high_ansi]
dMagnetic [-ini ini-file] [GAME] [-vmode high_ansi2]

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

dMagnetic [-ini ini-file] [GAME] [-vcols COLUMNS]
dMagnetic [-ini ini-file] [GAME] [-vrows ROWS]

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 [-ini ini-file] [GAME] [-vmode sixel] [-sres 1024x768]

where the -sres option offers a way to scale the images. The maximum allowed width is 1024 pixels.

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.

COMMAND LINE OPTIONS

[-bsd]
Shows the license.

[--help]
Shows the detailed help.

[--helpini]
Shows an example for a working dMagnetic.ini file.

[-mag MAGFILE.mag] [-gfx GFXFILE.gfx]

[-msdosdir DIRECTORY/]

[-tworsc DIRECTORY/TWO.RSC]

[-d64 DIRECTORY/FILE1.d64,DIRECTORY/FILE2.d64]
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, or as D64-images from the Commodore 64 releases.

[-ini dMagnetic.ini pawn]
[-ini dMagnetic.ini guild]
[-ini dMagnetic.ini jinxter]
[-ini dMagnetic.ini corruption]
[-ini dMagnetic.ini fish]
[-ini dMagnetic.ini pawn]
[-ini dMagnetic.ini myth]
[-ini dMagnetic.ini wonderland]
An alternative way to provide the location of the .mag and .gfx, 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

[-rmode pseudo] [-rseed SEED]
[-rmode real]
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.

[-vrows ROWS]
[-vcols COLUMNS]
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 command 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.

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

[-vmode none]
[-vmode monochrome]
[-vmode low_ansi]
[-vmode low_ansi2]
[-vmode high_ansi]
[-vmode high_ansi2]
[-vmode sixel] [-sres 1024x768]
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
