I finally got dungeon Keeper D3D running in fullspeed with the pc emulator PCem. I emulated a 200 mhz pc with win 98se. And voila dungeon keeper and the expansion runs with the d3d patch in full speed on win 10.

then gog should perhaps include that emulator instead of dosbox.

i think that this isnt possible because than GoG would need a licence for Win 98 from Microsoft.

Least you could do is give the instructions, or a "just unpack" folder where all you need to do is link PCem to the needed VM file and VHD.

So far I've seen neither clear cut instructions nor a ready to run pack out there. I know Ross from AccursedFarms runs one of those but he never made it available or explained how to make one.

What do you mean? Using PCem is just setting up the program and then installing the OS and software you run on it. There are no secrets. Getting a Win98 copy is certainly easy enough, and the OP just said he got it running well emulating a 200Mhz PC (I'm guessing a P200MMX).

Of course, in order to be able to emulate that PC full speed you need a beefy real one to start with. There is no amount of VHDs or settings that will make a 4th gen i3 run that well enough, for example.

Beefy it already is being a 8th gen i7 in the case of my laptop and a 5th gen i7 on my desktop, but my problem is in the setup. Tried a ripped Windows 98 copy with floppy image of the boot disk, didn't work. Tried using the self bootable Project Windows 9X iso, ditto.

My issue is a proper setup that can take me as far as the Windows installation screen. Either I messed up on some setting on PCem itself or I can't remember for the life of me how to go through the W98 installation process anymore. I already had a similar issue happen trying to install it on a bare metal pc.

Best I can do: https://www.mediafire.com/file/bwet0hpvruohk9c/PCemV15_Win98_Helper.zip/file

Those are all the user created files necessary that I can share. It includes the machine configuration for PCem itself, the BIOS settings for that machine, and a 2Gb HDD image with a single empty FAT32 partition. You still need PCem, the proper ROMs, and a Win98SE installation disk ISO (preferably a bootable one).

As long as you have those, uncompressing the above zip file to your PCem folder will give you have a basic machine configuration (P233MMX, 256Mb RAM, S3 video, AWE32 audio) to install Win98 into.

Remember to change the path to the CD image to be mounted, and the path to the HDD image ( [path to you PCem install]\disk_images\Win98_HDD1.img ).

The BIOS is setup to boot from the CD first. You will only need to change that after the first reboot that the Win98 installation does to "C only".

I have used it in the past and I tested now, in PCem v15, that this config can be used to install Win98SE properly and without errors, I cannot be certain at all that it will be useful for you to play Dungeon Keeper or any other game under Windows.

You will have to experiment that on your own, but I can tell you that I was able to run Nocturne in DirectX 6 hardware mode in this. The original minimum requirements were theoretically a Pentium 2 and an AGP video card (ATI Rage, Riva TNT, etc.)... Not bad for an emulated P1 and S3 to handle that.

Thanks, this is just what the doc ordered. I got PCem (even 86box if it's any better), I got the rom/bios files and at least two different isos to install W98SE with from what I got in physical media and ripped in the past. Thanks for reminding me to link the path to the HDD by the way.

Nice to know. Good luck and enjoy experimenting!
