As the title says I need help on installing those mods.
Most mods aren't "installed" in any significant way. You download the file and then try to load it into your game. If you don't like it then you simply delete the file.
If you
do like it then you can take extra steps, such as: setup a Character Folder so that the mod can be subsequently activated with a few clicks, add the file to your moreClothing list for ease-of-use, or include a Loader mod in your $INIT$ so that it will always be activated during startup. Some mods will even be packaged or distributed in a way which includes a pre-assembled Character Folder.
But you can always just dump the mod file into a convenient location (such as c:\SDT\mods) and then manually load it whenever you want. Installation isn't necessary.
You shouldn't hesitate to just load these files and see what happens. SDT mods almost never damage your game file or cause any long-term damage. At worst, the game will crash ... so you just restart the game and then ignore (or delete) that particular mod.
Do you load them in through the SWF mods tab like animtools?
Yes, you switch to the Modding tab and click the "Swf mod..." button. You can then select the MOD file via the browse window.
If the mod package includes a settings file
(usually a TXT file with a long filename) then you should copy it to your Settings folder before loading the mod. Mods will
usually load even if their settings files are missing or damaged, but they'll often revert to hardcoded default settings. In the case of the morecumspurts mod, default means
"the normal size and quantity of ejaculation". In other words: if the settings file is missing then the morecumspurts mod will have no real effect on gameplay.
Just never dealt with MOD files or AS files.
MOD files are described in the
newbie guide. I would encourage you to read it if you haven't already done so.
AS files (and some FLA files) contain
source code. They're shared for the benefit of other modders who may wish to edit the mod's behavior. You can ignore or delete these files.
