Dosbox doesn't start

[erbertmag]

Software: Recalbox version 18.07.13
Hardware: Raspberry PI 1 Model B

I'm having some trouble in getting Dosbox to work (I followed the instructions from https://github.com/recalbox/recalbox-os/wiki/How-to-use-DOSBox-to-emulate-DOS-games).

I've put the files for the "Duke nukem 3D" game in /recalbox/share/roms/dos/duke.pc, and inside that folder I've created a file dosbox.bat, that contains just two lines:

c:
duke3d.exe

When I try to open that Game in the emulationstation GUI, the DOSBOX logo appears for about 1 second (see below) and come back to the emulation station... Something is preventing DOSBOX from starting.

I've collected some logs just after I've tried to run the "Duke Nukem":

~/logs/es_launch_stderr.log:

ALSA lib seq_hw.c:466:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory

~/logs/es_launch_stdout.log:

SDL_VIDEO_GL_DRIVER=/usr/lib/libGLESv2.so /usr/bin/dosbox -userconf -exit /recalbox/share/roms/dos/duke.pc/dosbox.bat -c set ROOT=/recalbox/share/roms/dos/duke.pc -vkeybd /usr/share/dosbox -conf /recalbox/share/system/configs/dosbox/dosbox.conf

When I try to run the above command (exactly the contents of ~/logs/es_launch_stdout.log) from SSH, I got the following output:

DOSBox version SVN
Copyright 2002-2017 DOSBox Team, published under GNU GPL.

CONFIG:Loading primary settings from config file /recalbox/share/system/.dosbox/dosbox-SVN.conf
CONFIG:Loading additional settings from config file /recalbox/share/system/configs/dosbox/dosbox.conf
Exit to error: Could not initialize video: Invalid window

Besides Duke Nukem, I've tried to run another DOS program: an ancient DOS program called "visual player". Both works in my linux PC' dosbox but unfotunately dont work in recalbox.

Questions:

1. What I'm doing wrong?

2. Is there something that I can do, some other log to collect?

3. What "SDL_VIDEODRIVER" (https://wiki.libsdl.org/FAQUsingSDL) Recalbox's dosbox should use for RPi ? May be an issue related to this?

Thanks in advance.

Your only hope would be @lmerckx if he's not in holidays

@erbertmag change your dosbox.bat to

c:
dir
pause
duke3d.exe

and do a screen capture to show us what appears on the screen

I posted once my dosbox.cfg concerning DN3, you need a local dosbox.cfg, it will not run with the standard dosbox.conf.

@voljega I changed my dosbox.bat, and nothing changed (the dosbox splashscreen appears for about 1 second and then it returns to emulation station).

[erbertmag]

@dragu I've tested with your dosbox.cfg, and nothing changed.

I think that the problem may be related with the dosbox video driver not working ("Exit to error: Could not initialize video: Invalid window").

Yes, but this error message

CONFIG:Loading additional settings from config file /recalbox/share/system/configs/dosbox/dosbox.conf

shows that you are not working with a local (inside duke.pc) dosbox.cfg but with the original dosbox.conf that will not work here.

[erbertmag]

@dragu That message was before your advice. I confirm here that the ~/logs/es_launch_stdout.log contains the part of command line -conf /recalbox/share/roms/dos/duke.pc/dosbox.cfg.

@erbertmag Which version are you using? I have 1.3D and it works without problems on Recalbox (18.07.13)

Loading - Duke Nukem 3D DOS VERSION (v1.3D)

Menu - Duke Nukem 3D DOS VERSION (v1.3D)

My dosbox.bat:

• duke3d.exe

PS: Confirmed that the latest version of GoG also works without problems if you remove all "the additions"

@erbertmag seems impossible so I suggest double checking everything, because your screen should be on pause.

Pay attention to upper case in file and dir names, they shouldn't appear at all

@ebertmag
I just downloaded the dosbox version from 180713, easy with 7-Zip that also uncompress .img files, without necessary to install the OS.
And I can also confirm, DN3D is working with this 180713 version. But, my jackrabbit I not.
What shows that dosbox is not really a strait development over time. And the jackrabbit dosbox version is not usable for DN3D, 0 -1 framerates.

@lmerckx can you help me?

@erbertmag
Tu as bien défini une keymapper file xxxx.map au niveau de dosbox.cfg et qui existe dans ton répertoire ?
