Hey Solarius Scorch, thank you very much for the reply.
So I added the two lines to the specified sections, and no dice. I should have been more clear before: when I enable the mod in-game, I get a lockup where OpenXcom won't get past the DOS initialization screen, and the game won't start.
I could be wrong, but I think that there is an error on my part with the file structure of how the scoutdrone archive is compiled and thus extracted. Should I just be simply extracting the archive in my mod folder, or extracting it into it's own separate folder within mods? I ask this because if I just extract it to mods like all other archives, there are loose files (tank.rul, scoutdrone.rul) as well as another folder named the same as the one above it, scoutdrone. Within this scoutdrone folder (that is within a folder also named scoutdrone, there is another folder called drone which contains all the .gif files, except for three which are one level above, SD_UP.gif, floorbob_84.gif, and bigbobs_63. I think the intial DOS initialization error message mentioned something about not being able to access bigbobs_63.gif?
