Are the three DKII Bonus Packs included in the GOG version of DKII. I still have the original downloads. If GOG did not include them, can I run the original DKI2BonusPack1.exe (and the 2 and 3 exe's) and have them work?
apparently yes:

"The GoG version is the latest 1.7 version that came with the bonus packs included."
