Dogmaus: CDROM? what are you talking about? How do you own the game?
So, this game is in my GOG library, though it's been in it a long time so I can't remember how I acquired it - but I'm pretty sure it was on sale at some point years ago. The GOG Galaxy install of this game fails to launch on Windows 10, complaining about not finding VOCDATA on the CD, as in the OP. I tried opening the `dosbox_deathgate_single.conf` file and adding:
mount d "C:\Program Files (x86)\GOG Galaxy\Games\Death Gate\CD" Under the existing mount command. This allowed the game to launch into the initial intro movie, but it then crashes afterwards again with a similar complaint about the CREDITS file on the CD. Interestingly, on my Linux laptop, if I use the unofficial Minigalaxy client, that can download and run the game fine. I'm not sure what the difference is in the launch commands, but will find out...
EDIT: Got it working. Just replicated the folder structure for the Linux release of the game on GOG, and edited the relevant dosbox conf file. Instructions for any future folk who managed to buy the game during the short time it was on sale, and are struggling to get it to work on Windows with GOG Galaxy:

Note: I disabled cloud saves for Death Gate in the configuration section of the game in GOG Galaxy first, just to prevent it from messing around with the files, I'm not 100% sure disabling cloud saves is necessary, but if you do want cloud saves, you'll have to figure out the overlay mount in the dosbox conf file in the last step below (editing the conf file with replacement mount command), as I didn't bother.
* Open the game's folder in, by default,
"C:\Program Files (x86)\GOG Galaxy\Games\Death Gate" (you can use GOG Galaxy to open the folder in "manage installation -> show folder" if it's different for you).
* Create a new folder inside the Death Gate folder called "
data".
* Move the "
CD" folder from the Death Gate root folder into the new "
data" folder, so there is now a "
CD" subfolder inside the "
Death Gate\data" folder, i.e., "
Death Gate\data\CD" contains
INSTALL.EXE,
README.TXT and the
DGATE, DGATEVGA, TEST, UNIVBE50 folders, etc.
* Copy all the files with filenames in
CAPITAL LETTERS from the Death Gate root folder into the "
data" folder, such as "
ADLIB.MDI, ADLIBG.MDI, ADRV688.DIG" files and so on, leaving the root Death Gate folder only with the gog metadata files such as
.conf, .ini, .ico, etc files that are in lowercase or mixed case letters.

Here's an imgur link to an image showing the resulting folder file listings in the root "Death Gate" folder (left), and the new "Death Gate\data" folder (right), for clarity **
* Edit the
dosbox_deathgate_single.conf file from the Death Gate root folder in notepad, remove the existing mount command(s) in the
[autoexec] section, and replace them with a single mount command to the absolute path of the "
data" folder you created, e.g.:
mount c "C:\Program Files (x86)\GOG Galaxy\Games\Death Gate\data" **
Here's a pastebin link to the resulting .conf file: https://pastebin.com/raw/S5vSGp6c **

Game now seems to run fine. I guess it was just getting confused by the additional gog metadata/icon etc files mixed in with its own files, but separating the death gate game files + cd folder into a separate folder works, which seems to be equivalent in structure to the Linux version of the game.
Btw: I also changed the
goto launcher command to
goto game to skip the annoying launcher menu.
