Hi am a bit new here so i please forgive me if i post this in the wrong place . OK what i wanted to do was install a mod onto dragon ball z tenkaichi 3 , the file is (whatever).gcz i used dolphin to decompress the gcz file (note that the games runs perfect ) into a iso file when i extract or mount the iso it says that's its unreadable or corrupted but the game runs normal is there anything i could do that might be able to do ?
