JSWED v2.2.9 and v2.3.7

JSWED is a PC-hosted Jet Set Willy editor. It supports editing the following game engines:

The original 48k Jet Set Willy (JSW48).
Jet Set Willy 128k (JSW128)
Henry's Hoard (a JSW rip-off).
JSW64 (advanced 128k engine)
Manic Miner

Versions of JSWED exist for Win32 (Windows 95/98/ME, NT/2000) and for Linux with SDL. The Linux version also compiles and runs on BeOS and MacOS X.

JSWED is Free Software, released under the terms of the GNU General Public License (sic).

Download: Latest Stable Version

(3 Jan 2012: The original JSWED 2.2.9 installer was built with InstallShield and did not work on 64-bit systems. The installer has now been replaced with a 32-bit installer created by NSIS, which should.)

Windows programs and source (2078k)
Source only for Linux and other platforms (772k)

Download: Latest Unstable Version

Windows programs and source (3601k)
Source only for Linux and other platforms (1218k)

Note that if you redistribute the Windows files, you must include the source files in the distribution.

This version of JSWED does not come with sample data. It should be able to import .TAP files of any JSW128 game, .SNA files of nearly all JSW48 games, and .Z80 files of either. The unstable version should also be able to import snapshots of Jet Set Willy II and Manic Miner 128k.

The Competition (PC hosted)

The really old version of JSWED, version 1.0.7 (130k). This is inferior to JSWED 2.x in just about every way (it can only edit really old JSW128 games), but it does have very low system requirements - 256k and any video adaptor, even an MDA!
jclop by Geoff Eddy. Runs on the Linux console with svgalib. This is probably a better editor for earlier Geoff Mode games, but (in my biased opinion) not for any other type of JSW game.

The Competition (Spectrum hosted)

All known Spectrum-hosted JSW editors can be found at http://mdfs.net/Software/JSW/Editors/. These include:

JSEdit, the "official" JSW editor by Paul Rhodes.
JSWEdit, the "Softricks Mark II" editor (which produces a slightly different sort of game engine).
JSW Construction Kit, by Andrew Broad.
jswed (no relation!) by Rich Swann.
