Sorry to dig up an old thread, but I'm also trying to get Dark Sun v1.1 working under WinXP + VDMSound (2.0.4 I believe - the newest release before the 2.1 beta). If I try to run it with VDMSound (even if I set the game to use no sound), it crashes with an error message that is not legible due to the fact that it's running in a VGA graphics mode of some kind.
If I try to run without VDMS (i.e. double-clicking darksun.bat directly), I get an error message that says:
RESOURCE.GFF file not found. path = D:\OLDGAMES\DARKSUN\
But the file exists in that directory.
I tried running in DOSBox 0.60 and it runs fine (even with sound), except that I only have a PIII-550, so it's barely playable.
I tried making a FAT16 partition and running it from there (thinking that maybe it was an NTFS issue) and the same error appeared.
