Re: The Hanafuda [Sharp MZ-700]

I sent him a message in Japanese about two weeks ago, no response :(

I found a blog of a guy who claims to have a copy of it and says he backed it up on his computer with some recording device

That post is from 2013 so it's a little old. You can try and contact him on Twitter, he is still active there

I have no idea if he speaks English so you might want to have a translator handy
