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

Reverting display back to preferred mode -
@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 = normal2xAlso 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?
-
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.confSorry
SimEdit
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 -
@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.
-
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
output = surface
autolock = true
sensitivity = 100
waitonerror = true
priority = higher,normal
usescancodes = false
frameskip = 0
aspect = true
scaler = normal2x -
@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.

[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.

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

@Simrose Im glad we finally got it sorted it for you! Happy gaming! :D

Edit
Most games are playable but I do notice some like atomix not all the game is fitting. But maybe i can adjust those games. -
Did those same video settings work for all your dos games?
I am finding some of them not correct fitting.
Thanks
Sim -
@Simrose The game is appearing too small or they are being cut off?
-
@quicksilver
I can actually play the games what dont fit they just being cut off missing just a small part of top etc ( Full Screen) -
@Simrose hmm, im not sure, I havent seen this with any of my games.

Hi,
I've been working with Hurrican, the Linux port and switched over to the DOS version and came up with the DOSBOX issue on the RPI4. I setup my dosbox.conf per this thread as well as runcommand-onstart and runcommand-onend so it flips to 640x480. The image comes up centered but as you can see it leaves a lot of black border around the image. I assume it's keeping the aspect ratio. Is this expected?

@RussellB said in Dosbox on pi 4, game window is fullscreen but not centered on screen:
I assume it's keeping the aspect ratio. Is this expected?
If you have aspect=true then yes it will preserve the original aspect ratio.
-
Ok this is weird... using the same setup on another RPi4 a friend has the overscanning issue, and I don't. Using the same executable and the same dosbox-SVN.conf.
Ok... my bad... the TV did not support 640x480 properly. Switched to zoom mode and viola. Time for a new tv!
-
I made some quick tests yesterday and wanted to share my findings:
Since SDL1 is patched, dispmanx can be used again with the right aspect ratio (as in not streched across the whole screen) in dosbox.
This is true, and it's nice to see this improvement. Games just ran along nicely. I tested Blood with a resolution up to 640x480.
What didn't work was Ultima 7.2 (Serpent Isle), because there where severe slowdowns whenever the screen faded. I also tried System Shock with the same outcome: screenfading is very slow.
I did not change
output=surfacein the dosbox.conf, so that might be another go at it. But so far I would suggest to stick to the workaround quicksilver suggested.
