[Dosbox] Duke Nukem I Simple selection menu

[Dragu]

In Duke Nukem I, the 3 episodes are separated as individual .exe files.
So, to avoid creating different .pc directories, a modified dosbox.bat file.
After exit from games, the hand comes back to this menu and with key 4 it will exit to ES.

@echo off
:menu
cls
echo.
echo. 
echo.
echo.
echo.
echo DUKE NUKEM I
echo.
echo 1 = Episode 1 - Shrapnel City
echo 2 = Episode 2 - Mission: Moonbase
echo 3 = Episode 3 - Trapped in the Future
echo.
echo 4 = Quit
echo.
choice /n /c:1234 Make a selection:
if errorlevel ==4 goto leave
if errorlevel ==3 goto dn3
if errorlevel ==2 goto dn2
if errorlevel ==1 goto dn1
goto end

:dn1
DN1.EXE
goto menu

:dn2
DN2.EXE
goto menu

:dn3
DN3.EXE
goto menu

:leave
exit
:end

@dragu you should make a wiki entry with all your tutorials/tips! It would be very helpful for anyone trying to play those games and can easily be found.
Regardless if you do it or not, thanks for your contributions!

@paradadf @dragu yep I agree

Also could you post me somewhere a full copy of your dosbow.conf and dosbox.bat you did for LBA 1 & 2 ?
This will help me when i try to write a converter from ExoDOS Collection to Recalbox for any dos game as soon as 4.1 is available

[Dragu]

Wiki, I will first study before writing bulls**t
@voljega
For LBA1 and 2, the description for modification is here :
https://forum.recalbox.com/topic/8215/4-1-dosbox-little-big-adventure-1-and-2
But based on the files from gog.com. Anyway, there are alot of copies outside without the sound files, very bad. The mounting of the Iso-files is necessary because this games ask for presence of a CD in the drive as license. But fake-drive makes the deal.

[voljega]

@dragu yeah I know but I would like to see the full dosbox bat and conf/cfg ile to compare with exodos line by line

[paradadf]

@voljega I saw this the other day... it might serve you as inspiration.

I dont know how to send mails here so for lba1 (lba2 pretty the same)

dosbox.bat
RELENT.EXE

dosbox.cfg (local dosbox.conf)

# This is the configuration file for DOSBox 0.74. (Please use the latest version of DOSBox)
# Lines starting with a # are comment lines and are ignored by DOSBox.
# They are used to (briefly) document the effect of each option.

[sdl]
#       fullscreen: Start dosbox directly in fullscreen. (Press ALT-Enter to go back)
#            vsync: Sync to Vblank IF supported by the output device and renderer (if relevant).
#                   It can reduce screen flickering, but it can also result in a slow DOSBox.
#   fullresolution: What resolution to use for fullscreen: original, desktop or a fixed size (e.g. 1024x768).
#                     Using your monitor's native resolution with aspect=true might give the best results.
#                     If you end up with small window on a large screen, try an output different from surface.
# windowresolution: Scale the window to this size IF the output device supports hardware scaling.
#                     (output=surface does not!)
#           output: What video system to use for output.
#                   Possible values: surface, texture, texturenb.
#         renderer: Choose a renderer driver if output=texture or output=texturenb. Use output=auto for an automatic choice.
#                   Possible values: auto, opengl, software.
#         autolock: Mouse will automatically lock, if you click on the screen. (Press CTRL-F10 to unlock)
#      sensitivity: Mouse sensitivity.
#      waitonerror: Wait before closing the console if dosbox has an error.
#         priority: Priority levels for dosbox. Second entry behind the comma is for when dosbox is not focused/minimized.
#                     pause is only valid for the second entry.
#                   Possible values: lowest, lower, normal, higher, highest, pause.
#       mapperfile: File used to load/save the key/event mappings from. Resetmapper only works with the default value.

fullscreen=true
vsync=false
fullresolution=desktop
windowresolution=original
output=texture
renderer=auto
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal
mapperfile=lba1.map

[dosbox]
# language: Select another language file.
#  machine: The type of machine DOSBox tries to emulate.
#           Possible values: hercules, cga, tandy, pcjr, ega, vgaonly, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe.
# captures: Directory where things like wave, midi, screenshot get captured.
#  memsize: Amount of memory DOSBox has in megabytes.
#             This value is best left at its default to avoid problems with some games,
#             though few games might require a higher value.
#             There is generally no speed advantage when raising this value.

language=
machine=svga_s3
captures=capture
memsize=30

[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. If 'forced' is appended,
#            then the scaler will be used even if the result might not be desired.
#            Possible values: none, normal2x, normal3x, advmame2x, advmame3x, advinterp2x, advinterp3x, hq2x, hq3x, 2xsai, super2xsai, supereagle, tv2x, tv3x, rgb2x, rgb3x, scan2x, scan3x.

frameskip=0
aspect=false
scaler=normal2x

[cpu]
#      core: CPU Core used in emulation. auto will switch to dynamic if available and
#            appropriate.
#            Possible values: auto, dynamic, normal, simple.
#   cputype: CPU Type used in emulation. auto is the fastest choice.
#            Possible values: auto, 386, 386_slow, 486_slow, pentium_slow, 386_prefetch.
#    cycles: Amount of instructions DOSBox tries to emulate each millisecond.
#            Setting this value too high results in sound dropouts and lags.
#            Cycles can be set in 3 ways:
#              'auto'          tries to guess what a game needs.
#                              It usually works, but can fail for certain games.
#              'fixed #number' will set a fixed amount of cycles. This is what you usually
#                              need if 'auto' fails (Example: fixed 4000).
#              'max'           will allocate as much cycles as your computer is able to
#                              handle.
#            Possible values: auto, fixed, max.
#   cycleup: Amount of cycles to decrease/increase with keycombos.(CTRL-F11/CTRL-F12)
# cycledown: Setting it lower than 100 will be a percentage.

core=dynamic
cputype=auto
cycles=max
cycleup=100
cycledown=100

[mixer]
#   nosound: Enable silent mode, sound is still emulated though.
#      rate: Mixer sample rate, setting any device's rate higher than this will probably lower their sound quality.
#            Possible values: 44100, 48000, 32000, 22050, 16000, 11025, 8000, 49716.
# blocksize: Mixer block size, larger blocks might help sound stuttering but sound will also be more lagged.
#            Possible values: 1024, 2048, 4096, 8192, 512, 256.
# prebuffer: How many milliseconds of data to keep on top of the blocksize.

#             Possible values: default, win32, alsa, oss, coreaudio, coremidi, none.
# midiconfig: Special configuration options for the device driver. This is usually the id of the device you want to use.
#               or in the case of coreaudio, you can specify a soundfont here.
#               When using a Roland MT-32 rev. 0 as midi output device, some games may require a delay in order to prevent 'buffer overflow' issues.
#               In that case, add 'delaysysex', for example: midiconfig=2 delaysysex
#               See the README/Manual for more details.

#  oplemu: Provider for the OPL emulation. compat might provide better quality (see oplrate as well).
#          Possible values: default, compat, fast.
# oplrate: Sample rate of OPL music emulation. Use 49716 for highest quality (set the mixer rate accordingly).
#          Possible values: 44100, 49716, 48000, 32000, 22050, 16000, 11025, 8000.
