A Touhou PC-98 Extra+α with the Len'en 4 Engine ?!

From http://www.nicovideo.jp/watch/sm26592920 What a surprise. I defenitely wasn't expecting this from JynX at a time like this. Seems he has done this for a niconico contest. Obviously he is using the Len'en 4 engine with some of his patterns from the Touhou PC-98 remakes. I hope people stop saying these are only videos and not actual unrealeased games, this seems to be a good enough proof ^^
