@MultoBene you are trying to mount an image file to drive "2". It's expecting a letter like "d" not a number. You might look into using a .conf file instead for launching your ROMs. I'm not 100% sure if they work with lr-dosbox. Lr-dosbox had extremely poor performance last I tried so I haven't messed with it very much.

@quicksilver Oh! Thank you for all your advice <3

.sh files are not understood by lr-dosbox, but they should work withdosbox - as mentioned in the topic you referenced.

The preferred way would be to use .conf file for launching your games, where you can set your dosbox preferences and add an [autoexec] section for launching the game itself. For instance (game.conf):

[autoexec] MOUNT c /home/pi/RetroPie/roms/pc C: cd GameDir Game.exe EXIT

The .conf files are understood by both dosbox and lr-dosbox.

Thanks.

@nemo93 thanks for the reply! I tried it a while ago by following the guides about a year ago but it kept crashing so figured it might not be possible. Never mind, there's always 3.1! :-)

@mitu But haven't I already got that command in the code above at the beginning? After the path to xboxdrv?

@lazd @realgreg
sorry for the delay

Below is the best solution I found to get dosbox fullscreen and retain good performance

First we will need to install some dependencies:

sudo apt install xorg xserver-xorg-input-all

Then modify the emulators.cfg located at /opt/retropie/configs/pc/so that its contents look like this:

dosbox = "XINIT:bash /home/pi/RetroPie/roms/pc/+Start\ DOSBox.sh %ROM%" default = "dosbox"

Next make sure you are launching your DOS games using a .conf file with the right settings for each game, I have included a sample below (make sure to change the launching instructions under the [autoexec] section as needed)

# 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.

Lastly make sure that dispmanx is DISABLED for dosbox. Dispmanx seriously impacts performance with dosbox on the pi and is not needed if you are using the above method. (Im not entirely sure dispmanx still works when using an x session but it doesnt hurt to turn it off).

I made an ARM64 build of dosbox-core:

https://github.com/realnc/dosbox-core/releases/tag/latest_build_linux_arm

I don't actually know if it runs, since I don't have an ARM machine. In theory, it should run fine on RPi 4 since it's built on arm64v8 Ubuntu 16.04.

The first Need For speed is available and for PlayStation 1 with tha name Road & Track Presents - The Need for Speed .

@quicksilver Thank you so much!! I'm gonna give this a try now. Looks like alot but I'll try my best and let you know if I got it working

@StigNasty Do you still have that image file? Have you tried to copy it over to a pi 4 and see if performance is better?

@quicksilver

First I downloaded the dos

PC folder pops up in my roms

I put a folder named "maddog"
( with Mad Dog McCree.iso) in there

I Start Dosbox from the menue +Dosbox+

First thing I notice it says

Drive C is mounted "/home/pi/RetroPie/roms/pc/"

So the first thing I write is

imgmount d "/home/pi/RetroPie/roms/pc/maddog /Mad Dog McCree.iso" -t iso -fs iso

C:

Install Mad Dog McCree.iso

I get to the install page and it's says it's going to install is as

C:\maddog

So it completes

Note says to run press MADDOG

I'm back at dosbox

C:\MADDOG:

I type in MADDOG as show here

C:\MADDOG:MADDOG

The game runs

I followed your advice here as shown

About creating a .conf file with what you provided

So I restart emulation

I see 2 MADDOG files

I click them both

They both bring me to the command

I don't know what to do to run my game from here

The game only ran once , how come it won't start again , I thought I instlled it

Please help me , don't know what to do

Hope you could help

Thank you

@BuZz okidoki

I don't have any issues with Dosbox using the dev branch on a PI4 - did you set any special resolution for it through the Runcommand launch menu ? I just installed it from scratch and it's using the default configuration file installed by the scriptmodule.

Same thing with dosbox-sdl2 - it's working just after installed with the default configuration.

@neilclayt RetroPie doesn't support running in a desktop (pixel) session on the Pi. Most likely this is the cause of your dosbox issue. You have to exit the desktop session and start EmulationStation from the console - or just have EmulationStation start up by default and install Pixel separately as a port - https://retropie.org.uk/docs/FAQ/#where-did-the-desktop-go.

Please don't post links to rom/copyrighted material sites - https://retropie.org.uk/forum/topic/2/forum-rules.

@VictimRLSH

I tried:

EMS=true
XMS=true

Still didn't work :(

I too am experiencing the same issue. The game works perfectly in DOSbox on my PC and I'm using the exact same files and, from what I can see, the same DOSbox config options but through Retropie it crashes as described above.

My Raspberry Pi is a 3B+ as well.

Hi

When I was messing round with lr-dosbox about a year ago you could control the mouse using the gamepad analog stick. I think this is exactly what you are looking for.

Hope this helps, good luck.
