Following the common research strategies I get, that Mich. Emmerling is, as expected, "Michael Emmerling", and he was active with the profession "Buchbinder" already in 1785 (though with another address, then: "neben den Herrn Keller").
For this year 1785 we have already from Emmerling a business relation to Bieling in Nürnberg, which means, that he took Bieling products in his shop, likely as Kommissionsware (he got the products and paid, when he sold them).
So we still have to assume, that Bieling was the producer of the Spiel der Hoffnung (before August 1798 now).
Emmerling announced 1785 in the same Mitteilungsblatt as in 1798.
The newspaper appeared three times in a week, and the name of the publisher was "Conrad Neubauer" (earlier I had only "Neubauer").
Hechtel died December 1799 in a Blattern epidemic, short for the begin of new century. It's said, that many children died in this time cause of that plague. His death is noted in the ...
Monathliche historisch-litterarisch-artistische Anzeigen zur ältern und neuern Geschichte Nürnbergs: für das Jahr 1800
by Johann Carl Sigmund Kiefhaber
Before the text which reports about Hechtel there's a death announcement of a 3-years-old girl named Lina (a girl in its 3rd year), which notes the many children, who had died cause the plague. In this story it's said, that the child had announced her own death a few days before she died.
The priest, who served at the funeral of the girl, was the same who was active at the burial of Hechtel: Valentin Karl Veillodter

... written by a Karl Valentin Veillodter: "Vom Wiedersehen in Jenseits". The text says, that it is a reprint of an original edition of 1866, but the biography tells about a book production
of Veillodter „Ideen über Leben, Tod und Unsterblichkeit (Nürnberg 1809. 3. Aufl., 1818)"
Probably a later title change. The original title means translated "Ideas about life, death and immortality". The book seems to be rather popular.
So - somehow - very romantic conditions around the death of the young Hechtel, who just had made a humble running game with cards, but also had very idealistic ideas about education of young persons, as in "Sammlung freundschaftlicher Denkmale und kleine Lehren der Weisheit und Tugend. Zum Gebrauch in Stammbücher und zur Geistes- und Sittenveredlung junger Leute bestimmt." (Hechtel at Bieling 1798).
The two preachings of Veillodter at the both funerals (Hechtel and the young girl) must have been rather good. They are noted in a longer lists of his works short after his own death. Possibly Veillodter and Hechtel had a stronger friendship. They had a similar age, Veillodter * 1769, Hechtel * 1771.
