Building a Z-Machine in the worst possible language – Whitebeard's Realm (opens in new tab)

Portability between different computers is only a secondary reason for the Z-machine. The most important reason is code size, making the largest possible game that can fit on a floppy disk.

See the article “How to Fit a Large Program Into a Small Machine” by Marc S. Blank and S. W. Galley, in the July 1980 issue of Creative Computing. https://archive.org/details/creativecomputing-1980-07/page/n...

Is not the worst one, Zmachine.ps it's written in PostScript.

On Games, get Tristam Island and Calypso in the Z3 versions.

This is awesome. Presumably if this worked in Elm, Clojure would work too. There’s a very cool niche community around these games for those who don’t know. Vespers was one of the best games I ever played. Check out ifdb for games. There are mobile players available too.
