Henry's Hoard, released commercially in 1985, uses a heavily-modified JSW48 game engine. This fact was discovered by Philip Bee in April 2000. The gameplay is almost identical to Jet Set Willy, while the title screen, Game Over screen and lives display have been extensively modified.
Three versions of Henry's Hoard exist: the 1985 edition, the 1986 edition and the latter edition with minor changes (and the year 1987 mentioned in the scrolling message on the title screen), which appeared on Side A of "MicroHobby" Issue 188: Tape 7 in May 1989.
John Elliott has published an analysis of the Henry's Hoard game engine, focusing on the differences from the original JSW game engine and highlighting the differences between the 1985 and 1986 editions.
All versions of the game suffer from critical bugs that make them impossible to complete. The crucial one has been identified by John Elliott. The other problems are discussed here.
Daniel Gromann released bugfixed, completable files of all versions of Henry's Hoard in April 2017. A decade earlier, back in 2006, he also created Willy's Hoard, an expanded conversion of Henry's Hoard to the classic JSW48 game engine, with 49 rooms from Henry's Hoard, 26 brand-new rooms and Miner Willy as protagonist.
