DF: Landwarrior CD 1 for 1 copy

[greyzone]

You are the man!!!!
I lost access to the mitsumi, so I cant use clone cd, as I have a Teac 55s.
Tried copying everything but the Terrains.pff and Dflw.pff, and then copied them from the installed game to my burn folder, and then they were no longer 2.5 gb!!! the game installs, and runs just fine until I start a mission, then it quits with a sysdump message:-(( tried reloading it 2-3 times, no go..
Got any ideas??? This has cost me 7 cds up to this point
