Hello, I am running DOSBOX, and have used a utility called "eXoDOS Collection Importer" from this topic "https://retropie.org.uk/forum/topic/12400/exodos-collection-importer".

The importer works very well. I am having problems loading Under a Killing Moon, when launched, it loads DOSBOX, goes to the command prompt, then kicks back to the Emulationstation menu. No errors are shown, but I will paste the Dev/SHM runcommand.log.

I have tried a few tweaks of the Autoexec.bat file unsuccessfully, and hope someone will spot any problems. Most games run fine, and this is one I would really like to get going.

Thanks

I don't know your directory setup, but if you can, launch DOSBox without any game and then navigate to the game's directory through DOS and launch it from there. When executed this way, any errors should remain onscreen for you to take note of, as you're left at the DOS prompt rather than being dropped back to Emulation Station.

ChuckyP

Thanks for that. It is now stating that “No CD-ROM drive is available. Aborting Game”

There are 4 folders named DISK1, DISK2, DISK3, DISK4. Each folder contains the contents of a CD, but they are not .img.

@edmaul69 likely has the most experience around here with DOSBox and unique CD setups. Being from the eXoDOS Collection, I assume this is being launched from a .bat file, so it'll probably help to see its contents.

ChuckyP

The command that the autoexec.bat is trying to run is

MOUNT D /home/pi/RetroPie/roms/eXoDOS/KMOON/DISK1 -t iso -LABEL DISK1

And I am getting an “illegal type iso” error. There are no iso’s in the KMOON folder. Only folders that contain the CD data.

@chuckyp

You might try changing it to:

MOUNT D /home/pi/RetroPie/roms/eXoDOS/KMOON/DISK1 -t cdrom -LABEL DISK1

ChuckyP

It launches from my "pc" folder under home/pi/retroPie/roms, using a kmoon.sh file.

#!/bin/bash
/opt/retropie/emulators/dosbox/bin/dosbox -conf /opt/retropie/configs/pc/dosbox-SVN.conf -conf /home/pi/RetroPie/roms/eXoDOS/KMOON/AUTOEXEC.BAT -exit

then points to the eXoDOS folder under home/pi/RetroPie/roms/eXoDOS. and then launches the autoexec.bat posted above.

@chuckyp what mediamogul said. To use -t iso you would need to state imgmount instead of mount and it would have to be a .img, .cue or .iso file.

Edit: at any case i prefer to use “-t cdrom -iso” over “-t iso” as that doesnt specify a cd-rom drive and cant get a disc read error in some games.

ChuckyP

@edmaul69 Thanks, I did change it to IMGMOUNT previously, and it threw an error about that as well. I am trying the change just provided by mediamogul now.

ChuckyP

And with the change to "cdrom" in place of "iso" it is running well. Thanks for the super fast help. I will now be worthless for the next couple hours... For I am about to become Tex Murphy, and I have crimes to solve. :-)
