ok, i managed to get everything working in JK so that it runs on my system.  The only problem i am having now is that the screen flickers whenever i move.  If i hold still, it goes away, but comes back as soon as i move.  I have the ddraw.dll in my directory.  Both JK and JKE flicker in game.  I have searched for hours trying to fix it but nothing has worked.  Any help would be appreciated.
