Probably, I had a look through unLZ but couldn't find anything. Its most likely in there but I accidentally overlooked it ;_;. Even if you can't find the particles you should be able to easily change its palette at the very least.
I've only got two more to insert. It took a while to find a good/ fast way of indexing images since Windows 8.1 isn't palette friendly and then it took a while to break the backgrounds down to manageable 8x8 chunks. I'll be done by tonight or tomorrow morning at the very latest :P
