Hi KaleutLisaPrien did you save your emblems as TGA Files
and then place them in SHIII/Data/Emblems/SubEmblems
If you did'nt save them as TGA Files SHIII will not read them if you can't save them as a TGA File send me a Pm with your email address and Emblem file and i can convert it for you or download paint.net its free then you can convert it to a TGA File download link below
