Hi I bought game both Steam and GOG . I saw Steam version using GOG version . but there are some .dlls in Steam version , they are missing in the GOG version and why ?

e9701e9807952845b9cb3be0d4a6411d *ir41_32.dll
53c3c37fe4a610233a683dfb857eb233 *ir50_32.dll
e4e4bbf5a581c2b8aad6fb8e7988b9a9 *ffmpeg.dll

also

b6df88679ef024b1002362e0a0dd8955 *lgvid.dll (Steam)
2520677f00fa765c146979181af5d840 *lgvid.dll (GOG)

This one have different hash

Lastly some release docs or troubleshooting files etc. , txt type files not in the docs directory in the GOG version . I don' t understand sorry .

EDIT : It seems problem related NewDark update . Could you update files with a fresh update from here ?

http://systemshock.org/ss2tool/newdark.7z

And please delete some obselote.txt files from main folder .

the GOG version is using static linked lgvid.dll, that causes the difference. not sure why the rest of the dlls have been removed, but if the videos play, they aren't probably necessary anymore. but yeah, the docs should be included.

anyway, do NOT mess with NewDark manually, you will probably break more than you fix. run ss2tool if you wish to have all the latest fixes etc.

How you could broke game with same files ? (checked hashes)

cam_ext.cfg is customized, both for GOG and steam.

anyway, you know what the IT rule no. 1 is? if it ain't broke, don't fix it.

patch_ext.crf different too :)

correct. additively blended explosions.

;-) +1

27b52fd187e8cd584daf33dafef7abe2 *snd.crf is also different than CD version . Do you know what fixes included ?

yes, two sound files were broken, and have been fixed.
