S.T.A.L.K.E.R - No Intro Movies
 

was looking in the .db0 file with hexedit and came across some interesting string -nointro
so there it is..

to remove the commercial startup intro movies of the game simply put -nointro in the shortcut

i.e
shortcut>properties>target:
C:\Games\S.T.A.L.K.E.R\bin\XR_3DA.exe -nointro
