I don't know how to remap nor the process involved, but I know that when I've downloaded remapped things (for instance, AprilYSH's remapped Vickie/Posettes), there was a process involving a UVS file. I've seen the Export UVS command in UVMapper Pro, but as I've stated as naseum, I don't know the least about it. Lhiannan goes to look for a tutorial...
