Dosbox CD not found

10vorne

I want to get an old game running under Dosbox. The game is called “Herrscher der Meere”. I only had an ISO file, mounted it under Windows Dosbox, installed the game, and it ran under Windows Dosbox.

Then I copied the installation directory (and the iso) to the Pi. I wrote a conf, like I did it countless times with gog-games, it always worked, even with games that require a CD. I put the ISO in the installation directory.

I wrote the following conf file:

[IPX]
ipx=false

[autoexec]
# Lines in this section will be run at startup.
@ECHO OFF
mount C "/home/pi/RetroPie/roms/pc/HdM/"
imgmount d "/home/pi/RetroPie/roms/pc/HdM/HDM2011.iso" -t iso -fs iso
c:
HDMEERE.BAT
goto exit

:exit
exit

I saw that the game also uses a Setup.ini, it initially said

[PATH] InstallPath = D:\hdmeere\
AppPath = C:\ATTIC\HDMEERE\

After copying the installation folder to pc/hdm on the retropie I changed the setup.ini to

[PATH]
InstallPath = D:\hdmeere\
AppPath = C:\


[DIGITAL]
DeviceName  = Sound Blaster 16
DeviceIRQ   = 7
DeviceDMA   = 5
DevicePort  = 0x220
DeviceID    = 0xe018
DeviceString = "Sound Blaster 16"


[SOUND]
TimeTicks = 1
MouseClicks = 1
Effects = 50
Music   = 100
Speech  = 100


[OPTIONS]
Intro = 0
SmackQuality = 1

I tried many different things, but the game always says "CD not found"

Modify the conf file and leave only the mount commands in the [autoexec] section. See if there are any errors reported by DosBox before staring the game. Check that D: is mounted correctly by cd-ing into it and listing its contents.

@mitu It says "The image must be on a host or local drive"

mitu

@10vorne this means it cannot find the .iso file thus the D: drive is never created.

10vorne

@mitu The only problem seemed to be that the file ended in .ISO and I wrote .iso in the .conf file. That's it... now it works, everything else is as before.

mitu

@10vorne As I said, the file is/was not found. Linux filesystems are case-sensitive so .iso is not the same thing as .ISO (despite running the commands from dosbox, which emulates DOS).

@mitu Yes, the tipp to stop autostarting the game and to check the cd-mount was the right thing to do and kind of obvious for the solution. Sometimes you do not to see the wood for the trees, thank you for that.

I was actually aware of case-sensitivity, but I had the feeling that it didn't matter when it came to directory information in the conf files. Either I was mistaken or the file information is different than the directory information.

@10vorne said in Dosbox CD not found:

Yes, you'd expect (DOS) commands run via autoexec to behave similarly to real DOS (i.e. case-insensitive), but imgmount may be one of the exceptions since it's used to interact with the host (Linux in this case) filesystem.
