Firstly, compile d2x. Then stick it in a directory with these files from Descent 2 Registered (the version _does not_ matter). Shareware may work eventually, but the datafiles are of a different format. I needed these files: (in addition to the d2x binary) alien1.pig alien2.pig descent2.ham descent2.hog descent2.s11 descent2.s22 fire.pig groupa.pig ice.pig water.pig Note the filenames must be in _lower case_. It's important. Note that you don't have to run the D2 setup program to extract the files, just unarj descent2.sow from the cd.
