Drag and drop the skin file on XSkinMaker.exe (located in the “Tools” folder), the program will extract the images. Replace the trash icons and then drag and drop the file Config.txt on XSkinMaker.exe to create a new skin file.
Sure thing bro. Here's the old one. Made by Sosat. It was my long time favorite but had transparency issues, jagged corners and too small indicator. Here's the new one. Made by me, with textures extracted straight from OS X. I also provide a PSD file, if you want a different color indicator.
