Speedrunning an adventure...that's odd.
Make sure you have the latest drivers for your hardware before going further.
Check the GOG forums to see if other people that bought the game experience the same crashes as you (and how to fix them, if they did).
Anyway, help people help you:
-OS
-DosBox version and configuration (specially video and cycles).
-Mountings.
-King's Quest configuration.
-Does it crash somewhere specifically? Or at random?
-Does it crash when starting from the beginning or only when loading a saved game?

Provide as much information as you can and as detailed as possible, otherwise...you won't get far.

There should be some sort of error log in the main DOSBox directory, I think. [EDIT: It's called stderr.txt , and it only appears if DOSBox is started with -noconsole , which is standard for GOG's shortcuts.]

If you are taking pictures or recording movies, DOSBox will crash without warning if there is not enough space on the partition where it is trying to save the data. (I noted that three years ago, anyway.)

You can also rem out the exit line in the [autoexec] section of the game's conf file. This will keep DOSBox from closing when the game exits so you can read any error messages from the game.

I want to post my diaxdg file to see if someone can help me but I can't figure out how to add it to a reply?

Don't, I said to post mountings, DosBox version and config, and such, reread my post, I never said dxdiag.

-OS Windows 7 home edition
-DosBox version and configuration (specially video and cycles). .74, I've been playing around with the graphics configuration but nothing seems to fix it
-Mountings. ?
-King's Quest configuration. gog.com version
-Does it crash somewhere specifically? Or at random? Three separate times, once while starting to climb the cliffs of logic, once while on the isle of mists for the second time, and once in the secret passage of the castle
-Does it crash when starting from the beginning or only when loading a saved game? only specifically during those times, not while loading or starting the game

Find "Mount" in the configuration file.

As I asked in my earlier post:
Is there a file named stderr.txt in the same directory as dosbox.exe?
Do you still have free space on your hard drives?

IIGS_User: I'm using the GOG version, which only has a graphics configurator, there is no mount listed there.

Jorpho no, I don't see that file, and yes I have plenty of free space available, around 75% free.

The stderr.txt will probably be found in the game's folder or possibly in the Virtual Store.

Did you try to remove the "exit" command in the game's conf file? If it is the game crashing instead of DOSBox itself, you should see any error messages.

Did you look around and ask in the gog forums to see if anyone else has the same problem?

how do I open the conf file?

And yes, I did post it to the gog forums asking for help, but no one answered me, maybe I'll try that again

Open it in Notepad.

I removed the exit command but it's still crashing. What other things can I change in the conf files to fix this? Any ideas?

Then DOSBox itself is crashing, not the game. Try changing the conf to just:

1[cpu]
2core= normal
3cycles= 10000
4
5[autoexec]
6cls
7mount c .
8c:
9cd \
10SIERRA.EXE .\RESOURCE.CFG
11exit

And see if it still crashes.

When I put that in, I get the box popping up that shows it's dosbox but the game doesn't load. Here's what it says originally (I saved it before trying that, thank goodness):

[autoexec]
# Lines in this section will be run at startup.
mount C "..\King's Quest 6"
c:
cls

I played it after adding that cpu section and it still crashed
sierra

Try uninstalling and doing a clean re-install. If it still crashes, I'll have to install GOG's version to see what may be going on.

ok

After completely uninstalling (including saves) I did a quick run but it is still happening. If you want to see what I'm dealing with, I'm streaming some of my attempts, this is my latest full run with three separate crashes. The first one happens not long after 18:15.
