Extensions to the JSW48 Game Engine

During 1984 and 1985 while I was writing my JSW Room editor, I also made a few changes to the JSW48 game engine to add features or to increase functionality. I originally rewrote the whole code, but then I changed tack and tried to ensure that the changes were as small as possible and could be patched on top of existing code. This meant that I could distribute my improvements without having to distribute the complete code.

In July 2006 there was a discussion on the Jet Set Willy list on using Intel Hex files for distributing patched. I have created hex patchfiles for each of my patches.

The patches are described here:

Since typing up my commented JSW assembly file I have added some more patches to the code. These are: The full code is available here:
JetSet.sna 48K
Standard Snapshot 		JetSet.ssn 64K
Speculator Snapshot 		JetSet.tap 32K
Spectrum Tapefile 		JSW.tap 32K
