RE: 2 things.

Noteskins are done by the program, AFAIK.

For 12th notes, I'd just do it in the editor, but if you're absolute notepad only:

In each count there's a given number of notes. 4 for 4th notes, 8 for 8th notes, 12 for 12th notes and so on. In a .sm file, which are easier to make IMO, you need to make sure there are X number of lines in the code, where X is the kind of notes to use.

Example:
This will produce a 12th note in the column specified by the one. 1000 makes a left, 0100 makes down, 0010 makes up, and 0001 makes right.

For DWI, your code will look like this:
This will produce 12th notes. The numbers correspond with the numpad. 4 is left, 2 is down, 8 is up, and 6 is right. This line is spaced with zeros because it's actually 24th notes without the 24th part. I'm fairly sure you HAVE to do it this way.

I hope that helped, I do a lot of editing in notepad, and I did a few sims of my own in notepad (Xepher).

When you get a chance, go play Xepher (BMS is down though, so I could send over AIM, invisiblewar88) or I can send you AAA v2 which is definitely awesome. Of course, that's me :P

Solution: Don't use the manual notepad way for making simfiles. Thats too oldschool.

Use Stepmania editor.

Noteskins aren't part of the DWI. They're a StepMania setting.
