Dosbox

dosbox est un émulateur dos pour différents systèmes dont linux.

Les options de la ligne de commande :

-fullscreen :
Démarre en plein écran.

-startmapper :
pour mapper les touches utilisées par dosbox.

-noautoexec :
Ne tient pas compte des lignes de la section "autoexec" du fichier de config..

-scaler scaler :
Uses the graphical scaler specified by scaler. See the configu-
ration file for the available scalers

-forcescaler scaler :
Similar to the -scaler parameter, but tries to force usage of
the specified scaler even if it might not fit.

-c command :
Runs the specified command before running file. Multiple com-
mands can be specified. Each command should start with -c
though. A command can be : an Internal Program, a DOS command or
an executable on a mounted drive.

-conf configfile :
Start dosbox with the options specified in configfile. This file
has a section in which you can put commands you wish to execute
on startup. Multiple configfiles can be present at the command-
line.

-lang langfile :
Start dosbox with the language specified in langfile.

-exit :
dosbox will close itself when the DOS program specified by
fileends.

-machine machinetype :
Setup dosbox to emulate a specific type of machine. Valid
choices are : hercules, cga, pcjr, tandy, vga(default). The
machinetype has influence on both the videocard and the avail-
able soundcards.

-version :
Output version information and exit. Useful for frontends.

Sous linux, on crée le fichier de config avec la commande suivante :

dosbox -c ’config -writeconf dosbox.conf’

On obtient un fichier dosbox.conf qui ressemble à ça :

# This is the configurationfile for DOSBox 0.72.
# Lines starting with a # are commentlines.
# They are used to (briefly) document the effect of each option.

[sdl]
# fullscreen — Start dosbox directly in fullscreen.
# fulldouble — Use double buffering in fullscreen.
# fullresolution — What resolution to use for fullscreen : original or fixed size (e.g. 1024x768).
# windowresolution — Scale the window to this size IF the output device supports hardware scaling.
# output — What to use for output : surface,overlay,opengl,openglnb.
# autolock — Mouse will automatically lock, if you click on the screen.
# sensitiviy — Mouse sensitivity.
# waitonerror — Wait before closing the console if dosbox has an error.
# priority — Priority levels for dosbox : lowest,lower,normal,higher,highest,pause (when not focussed).
# Second entry behind the comma is for when dosbox is not focused/minimized.
# mapperfile — File used to load/save the key/event mappings from.
# usescancodes — Avoid usage of symkeys, might not work on all operating systems.

# machine — The type of machine tries to emulate:hercules,cga,tandy,pcjr,vga.
# captures — Directory where things like wave,midi,screenshot get captured.

language=
machine=vga
captures=capture
memsize=16

[render]
# frameskip — How many frames DOSBox skips before drawing one.
# aspect — Do aspect correction, if your output method doesn’t support scaling this can slow things down !.
# scaler — Scaler used to enlarge/enhance low resolution modes.
# Supported are none,normal2x,normal3x,advmame2x,advmame3x,hq2x,hq3x,
# 2xsai,super2xsai,supereagle,advinterp2x,advinterp3x,
# tv2x,tv3x,rgb2x,rgb3x,scan2x,scan3x.
# If forced is appended (like scaler=hq2x forced), the scaler will be used
# even if the result might not be desired.

[cpu]
# core — CPU Core used in emulation : normal,simple,dynamic,auto.
# auto switches from normal to dynamic if appropriate.
# cycles — Amount of instructions DOSBox tries to emulate each millisecond.
# Setting this value too high results in sound dropouts and lags.
# You can also let DOSBox guess the correct value by setting it to max.
# The default setting (auto) switches to max if appropriate.
# cycleup — Amount of cycles to increase/decrease with keycombo.
# cycledown Setting it lower than 100 will be a percentage.

core=auto
cycles=auto
cycleup=500
cycledown=20

[mixer]
# nosound — Enable silent mode, sound is still emulated though.
# rate — Mixer sample rate, setting any devices higher than this will
# probably lower their sound quality.
# blocksize — Mixer block size, larger blocks might help sound stuttering
# but sound will also be more lagged.
# prebuffer — How many milliseconds of data to keep on top of the blocksize.

rate=22050
blocksize=2048
prebuffer=10

[midi]
# mpu401 — Type of MPU-401 to emulate : none, uart or intelligent.

Monter des images ISO

On monte les images ISO avec l’instruction « imgmount ». Les différentes options sont :

IMGMOUNT LECTEUR [fichier_image] -t [image_type] -fs [image_format]
 size [tailleDesSecteurs, secteursParTête, têtes, cylindres -u LECTEUR]

LECTEUR : la lettre du lecteur à créer.

fichier_image : l’emplacement de votre fichier image, sur votre vrai disque ou celui de dosbox. On peut spécifier plusieurs fichier et ensuite basculer de l’un à l’autre avec la combinaison de toucle -F4
