I was here to inquire about this question because I know it has been done before, but the subject seems to have vanished from any search engine I have used.
What I mean is, I can't seem to find any ports of any skin packs from the legacy console editions to Java (meaning, the images taken out from the files). Before, I was able to find an extraction of Skin Pack 4 about 3 years ago, where I was able to essentially fix up the "Wolf" skin and make it work with Java Edition's layer system. But I can't seem to find it anymore. Also, I was able to get an extract of Skin Pack 2, where the "Elf" skin was able to be used straight out-of-the box (although I believe I had to fix the ears I'm not too sure).
I was trying to find a conversion of the default skin pack on Alex's side. The wiki has all of Steve's skins, but Alex's are not there at all, which leads me to you all.
Has anyone found anything as of late that is related to what I am saying?
I can link the "Wolf" and "Elf" skin to provide legitimacy to my story if need be.
