Hey guys, I've made my own custom textures for Super Smash Bros. Brawl, but when I try to put them all back into a .pac/pcs (whatever it is), the program (called ash something I think?) says "ERROR: The image you provided doesn't have an indexed palette. It will be ignored. Press any key to continue..." what am I doing wrong? how do I fix it so I can actually USE my textures?
