Hey! Thanks for getting back to me!
Your procedure makes sense. I didn't know the 1.0 milestone was considered to be outdated, so that is helpful info.
Lorcan's music files can be used by directly substituting them in the SOUND folder. His files are .ogg, and the originals are .mid, so I deleted the midi files just to be sure. This method worked for me. In case anyone else is reading this, the music files I am talking about are amazing and can be found by searching for Cydonia's Fall on the mod website and look for Lorcan's name.
Ignore/delete the milestone 1.0 version. You don't need it to run the nightlies and nearly all current mods won't run on the 1.0 version since it's long outdated. Having both the 1.0 and the nightly installed can easily lead to confusion
A short list:
* Get the nightly and unzip it to your Desktop
* Open the original game's folder. Copy the GEODATA, GEOGRAPH, MAPS, ROUTES, SOUND, TERRAIN, UFOGRAPH, UFOINTRO and UNITS folders to the /openxcom/UFO/ folder of the nightly
* Run the nightly to create the C:/users/yourname/Documents/OpenXCom (if it isn't already created)
* Copy the FMP folder to C:/users/yourname/Documents/OpenXCom/mods/
* I don't know how Lorcan's mod works - you either use it to replace the files on the /SOUND folder of /openxcom/UFO/, or you need to install it by copying its folder to C:/users/yourname/Documents/OpenXCom/mods/
* Start OpenXCom. Go to options and select the FMP on the mod list
Which version of the FMP are you using btw?
I am using FMP version 1.9.3. My biggest issue is that I don't know how to tell that I have actually installed these mods properly. I would've expected a long list on the Options dialogue from the main menu, but I think I am only seeing stuff from the openxcom patch or the 1.0 milestone. What is an example of a mod that would show up in the options that is exclusively from FMP 1.9.3? Otherwise, I was thinking that if I start a new game and try to build the larger Living Quarters and they are actually an option then I have succeeded, but is that correct? Are there any other ways to tell? Which mods from the FMP are readily visible without investing too much time into a game?
