This is rather weird:

^-> changes between retail version of the path and the Steam one. Why those two patches with the same version differs so much? Consider the fact all other files between editions completely the same...

Anyway, the question is: if I repack the Patch.dv2 into main DV2s - wouldit work with previous (hotfix one) version?

I can't play the game with latest patch, the reason of that I described on previous page: new version ignores the LockSteMode directive and leaves it always enabled. I can say that for sure, coz when LSM enabled my mouse stop working (checked and tested on hotifx).
