I have the Steam version but these will still work. The nameless ones and Virtual Headache were made with the in-game palette editor. Also I don't have screenshots handy, otherwise they'd all have names.
(BTW the in-game palette editor needs a way to name your palette.)
I leave it to the user to remember to change the reference numbers.
