Sorry if this is the wrong place. I'm in the same/a similar position here.
I have followed these instructions-
animtools for loadermode (to load automatically on startup):
1. open the 'animtoolsV12settings.txt' file, and change the 'persistonresetforinitfolder=0' setting to be 'persistonresetforinitfolder=1' . save and close the settings file. this allows the mod to stay active after resetting. Was already done.
2. copy 'animtoolsV12.swf' and 'animtoolsV12settings.txt' and paste them into the 'root/Mods/$INIT' folder. Did that.
3. update the 'Mods.txt' file in the '$INIT' folder to include animtoolsV12. to do this, add the text line 'animtoolsV12.swf' in the 'Mods.txt' file. Did That.
4. move the animtools_positions folder to the loader 'Settings' folder. Did that.
after doing so, animtoolsV12 will automatically be loaded up in "loadermode" when starting the 'loader'
If this means Loader.swf in my Loader.v5.45e.ModGuy folder, it does nothing of the sort. I can not get those arrows to show anything when clicked, it's just blank.
P.S. Yes I'm a modder, but new to SD.
UPDATE:
Figured it out by fidgeting around with options for anyone stuck where I was a minute ago
so if you're done with these steps load the swf file you put in $INIT$ in the modding type like you would an outfit for SD, and then the options will show up for you in the loader section as in TissueSaviour's photos.
