I like to run all of my DOS games, including the ones I download from GOG, from Taewoong's DosBox SVN build for Windows. I always read how GOG sets up the games to run and I essentially copy it. With Dungeon Keeper, however, it has not worked. Has any one managed to get this running on an external DosBox setup that wasn't supplied by GOG.com, and, if so, how?

Can't you just replace GOG's DosBox with Taewoong's DosBox?

So, go to the game folder and look for DOSBOX folder. Open it and replace all files with Taewoong's DosBox files.
