Jet Set Willy z88
This project contains the source code assets for building the z88 port of ZX Spectrum game Jet Set Willy.
Compilation
To compile you'll need a modern version of z88dk setup and available in the path. The application can then be generated
by invoking make.
A .epr file and an OZ5 .app file will be generated.
Background
The source code is pretty much as it was when released in 1998, so contains (amongst other things):
- Commented out code
- Cryptic labels
- Development comments/queries from the disassembly
- False comments
The following changes have been made:
- Update to assemble with the version of z80asm within z88dk
- Updates to remove old email addresses
- Interrupts aren't disabled whilst playing the themetune
As a result, the version has been bumped.
The game itself has been extensively disassembled, for information see, for example: https://skoolkit.ca/disassemblies/jet_set_willy/
In-game Controls
The preset keys are:
- Left - O
- Right - P
- Jump - Space
- Pause - H
These movement keys can be redefined to suit your playing style/hand size!
There is also a set of control keys which cannot be redefined:
- ESC - Quit back to intro from game
- TAB - Toggle screen size - mini/standard
- DEL - Toggle inverse background
