Description of "Jet Set Willy 64" versions taken from Dr. Andrew Broad's list of Manic Miner and Jet Set Willy games (July 2006) (http://www.geocities.com/andrewbroad/spectrum/willy/list.html)



There are six variants of the JSW64 game-engine (and of the original JSW64): V, W, X, Y, Z and [. Variants V and W have 128 rooms, while X, Y, Z and [ have 64 rooms. The variants also differ in the number of guardians per room, the number of cell-classes per room, and whether the cell-type of each cell-class is set globally or on a room-by-room basis - see John Elliott's JSW64 Room Formats (http://www.seasip.demon.co.uk/Jsw/jsw64room.html) for technical details.



A few revisions of John Elliott's original JSW64 exist (Version refers to the room-data, Hacklevel to the game-engine): 

- Version 0.01 Hacklevel 11 (2005) was the first gamma-release. 

- Version 0.01 Hacklevel 11a is the latest gamma-release of JSW64 the game: it fixes a bug in the DOS installer.

- Hacklevel 12 (2006) adds traps as a new cell-type, and fixes a bug in the memory-map.

- Whenever you load a JSW64 game in JSWED, it automatically upgrades it to the highest Hacklevel (HL12 as of JSWED v2.2.9 and later).

The Files:



John Elliott has released the game as a DOS installer. The enclosed files were created from its current version (July 2006), then loaded into the current stable version of John Elliott's JSWED (v. 2.2.9), which automatically upgraded HL11 to HL12, and saved. Thus they are the highest possible (although not officially released) revision existing at this point.
