Do you mean a link to the actual file from the consoles? Or a version modded into the PC version? If it's the former I'd rather not see it publicly posted. Discussion about how to extract it should be fine as the assumption is that someone purchased/downloaded the file legitimately on their own copy.
It's a version modded into the pc version. I had to take an existing pc costume file and delete all it's mesh data, then inject the ragnarok mesh data into that now empty costume file the same way as bringing in a custom made mesh
