Spent some time looking for this but.. yeah.
Probably not happening, unless you can call your good friend who lives in Japan to dig this up for you.
It's like it was deleted from the internet by an interdimensional entity. Not even Waffle's catalog on DL site has it, it seems.
Seems like it, leave it to some obscure pirate site to have something ancient which not even its devs sell in their shop anymore.
Provided the links still work.
