The easiest way to identy them is when they have [16:10] in their title. The only 16:10 skins I know right of my head are my own (Cyber Ene, Clear Futuristic Miku) and IJN Yamashiro
You can find some 16:10 skins here. If those don't work right after you install them, check out the Extras folder or !extras.txt file for the 16:10 assets. (it's in the main skin folder)
