Dosbox on pi 4, game window is fullscreen but not centered on screen

Simrose

@quicksilver
The resoltion on tv info says 1920x1080p
so that must be the issue that its not switching and the scripts not activated.
i have them in correct location, do i need to do anything with them before running games.
Sorry took along time to respond
Thanks
Sim

quicksilver

@Simrose try this: drop to the command line (press f4 if youre in emulation station) and type

tvservice -m DMT

Post the output here.

Also do

tvservice -m CEA

And post the output here

@Simrose Ok, so now we know that your TV should support DMT mode 4. Can you verify that your runcommand-onend.sh and runcommand-onstart.sh are named correctly? Can you verify that they are located at /opt/retropie/configs/all/? Can you post the content of each file?

Simrose

@quicksilver

location
runcommand-onend.sh contains
#! /usr/bin/env bash
echo "Hello logfile - runcommand-onend checking in here" >&2
#START DOSBOX SECTION - SNIP HERE IF PASTING INTO EXISITNG SCRIPT
if [ $2 = "dosbox" ]
then
echo "Reverting display back to preferred mode" >&2
tvservice -p
fi
#END DOSBOX SECTION
runcommand-onstart.sh file contanins
#! /usr/bin/env bash
echo "Hello logfile - runcommand-onstart checking in here" >&2
#START DOSBOX SECTION - SNIP CONTENTS IF PASTING INTO EXISTING SCRIPT
if [ $2 = "dosbox" ]
then
echo "dosbox detected - changing video mode to 640x480@60hz" >&2
tvservice -e "DMT 4"
fi
#END DOSBOX SECTION

quicksilver

@Simrose in the start script try changing

tvservice -e "DMT 4"

to

tvservice -e "CEA 1"

also, can you run a dosbox game, quit the game. Then post the contents of
/dev/shm/runcommand.log?

Something is wrong with the formatting of your scripts. I suspect you have windows style line endings instead of Unix style. Delete your scripts and download and just use mine exactly as they are.

https://mega.nz/folder/ddJTWKaZ#JQV_WCprVMAP77qRnlGmEg

In the future when you write a script that is intended to be used on a Linux machine, make sure you use a program like notepad++ with formating set to Unix.

Simrose

@quicksilver

Thanks I'm just waiting to get a chance to try and will let you know. I was using notepad ++ but didn't change format thanks for the tip. I never experimented with them before.
Sim

Simrose

@quicksilver I am using your scripts and still no good. I can see the script message now and the game does play but the video is small in top left and rest of the screen is a graphical mess. I have no idea why. I really want to get it working.
Thanks Sim

@Simrose are you using these settings in your arkanoid.conf?

fullscreen = true
fulldouble       = false
fullresolution = original
windowresolution = original
output = surface
autolock         = true
sensitivity      = 100
waitonerror      = true
priority         = higher,normal
usescancodes = false
frameskip = 0
aspect    = true
scaler = normal2x

Also when you post code or configs here on the forums put them in a code block by placing three back ticks (```) above your code and three below it. The back ticks should be on their own lines.

Also when was the last time you updated dosbox?

Simrose

@quicksilver

No I just thought that we just had to change the Dosbox svn like you have it above.

I just updated from source I'll try again then after that I'll try changing the Conf settings for the actual game.

Is that what I should of done before?

Should i keep in dosbox-SVN.conf
fullscreen = true
fulldouble = false
fullresolution = desktop
windowresolution = original
output = overlay
autolock = true
sensitivity = 100
waitonerror = true
priority = higher,normal
mapperfile = mapper-SVN.map
usescancodes = false
frameskip = 0
aspect = true
scaler = normal2x
Or should i restore that file to default and just change in arkanoid.conf

Sorry
Sim

Edit
I added those above values to the arkanoid.conf and now the screen is much to large and doesnt fit into my resolution.

The game runs but i would esitmate the top left corner of the game fills the whole screen.
thanks
Sim

quicksilver

@Simrose try to restore the default dosbox-svn.conf to default and just change those settings in the arkanoid.conf.

I can post the default settings if needed. Or delete the dosbox-svn.conf right before updating dosbox and it should get replaced.

Simrose

I kept the original but that didnt work. I deleted dosbox-svn.conf and now reinstalling so hopefully will work after that.
this is my arkanoid.conf
mount c "/home/pi/RetroPie/roms/pc/.data/arkanoid.pc"
c:
ARKANOID.COM
EXIT
fullscreen = true
fulldouble = false
fullresolution = original
windowresolution = original

waitonerror = true

quicksilver

@Simrose can you post your full arkanoid.conf?

Remember put three back ticks (```) above and below it (no parentheses)

@Simrose The formatting for your arkanoid.conf is completely wrong. Your screen settings need to be in their own [sdl] section. Delete the contents of your arkanoid.conf and copy/paste the entirety what I have below instead. For any other dos games using .conf files use what I have below as a template.

# This is the configuration file for DOSBox SVN. (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)
#       fulldouble: Use double buffering in fullscreen. 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.On Windows 10 with display scaling (Scale and layout) set to a value above 100%, it is recommended
#                     to use a lower full/windowresolution, in order to avoid window size problems.
# 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, overlay.
#         autolock: Mouse will automatically lock, if you click on the screen. (Press CTRL-F10 to unlock)
#      sensitivity: Mouse sensitivity. The optional second parameter specifies vertical sensitivity (e.g. 100,-50).
#      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.
#     usescancodes: Avoid usage of symkeys, might not work on all operating systems.

#              then the scaler will be used even if the result might not be desired.
#              To fit a scaler in the resolution used at full screen may require a border or side bars,
#              to fill the screen entirely, depending on your hardware, a different scaler/fullresolution might work.
#              Possible values: none, normal2x, normal3x, advmame2x, advmame3x, advinterp2x, advinterp3x, hq2x, hq3x, 2xsai, super2xsai, supereagle, tv2x, tv3x, rgb2x, rgb3x, scan2x, scan3x.

#    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.

[mixer]

#               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

That is so kind of you. It is working now with your settings. I will do the same for each game.

I am so happy :-)
Thanks
