I found a wii theme I've been looking for for AGES. However, it was a CSM for 4.3U, and I'm 4.3E. So, I used thememii to convert the CSM to an MYM. Now, would this MYM be region-independent? As in, if I now used this extracted mym to make a 4.3E CSM, would that be safe? Or would the theme still be incompatible?
