QFG4 is the best of the series, but it is also the buggiest of them all. My CD has both a windows version and a DOS version and, even when I had true DOS, I was forced to use the windows version. In other words, the problem may not be DOSBOX per se, but the game itself. If you have the Windows version I recommend playing it, despite its nuances. If you don't you will wind up with numerous crashes even if you can get the game running smoothly. Also, check for patch disk at Sierra as well. Sorry, I couldn't be of much more help.

Thanks!
I chose the DOS version, namely because it was the Windows one that gave me the numerous crashes. And yes, I have it patched with all three released patches.
I am now still wondering how to use a speed "modifier" within DOSBox.
Of course, Speedset has unceremoniously kicked me out of the DOSBox, once I tried to use it.

you've tried ctrl-f12 and ctrl-f8 i presume ?

I appreciate the irony, but no, I haven't. I don't know how...
I know that Ctrl-F8 is for increasing frameskip,
and
Ctrl-F12 is for speedup emulation. And that's it.
Should I use them both? In what order?
How many times?
Thank you, and sorry for the ignorance.

well in the readme it's described in to detail
but basicly

watch your cpu usage.

increase speed with ctrl-f12
when you're near the max. Free some cpu time with ctrl-f8

But everything is governed by the cpu usage.

Thanks, I am off to it!
P.S. It works fine! Thank you so much.
I had read the Readme.txt, but it was completely different when you took the time to explain. I do appreciate it.

With the new timer bug patch found on the message board of SpaceQuest.Net http://forum.spacequest.net/viewtopic.php?t=1 … 4a97c6a15149b24 You can run the DOS version of the game with just VDMSound. It fixes all of the Timer bugs in QfG4.
