-This is the beginnings of a disassembly of the [ZX Spectrum version of Chase H.Q. by Ocean Software](https://spectrumcomputing.co.uk/entry/903/ZX-Spectrum/Chase_HQ). Initially this is only of the 48K version - and the first level/stage at that. The 128K version is better (loads all the levels at once, has AY music, menu screen animations, ...) but it has a lot more code to consider, so it's easier to start off with 48K stage 1 first.

 In this repository is a [SkoolKit](https://skoolkit.ca/) _control_ file which you can use to disassemble the game. This works with the game when it is in a "pristine" just-loaded state. See below for how to make a pristine snapshot and instructions on how to drive SkoolKit. I've provided a Makefile to automate most of the required steps.
 
 The current disassembly is [here](https://dpt.github.io/ChaseHQ/).

 - Option (1) is to run the game in the [Spectrum Analyser interactive disassembler](https://colourclash.co.uk/spectrum-analyser/) and look for clues.
 - Option (2) is to stare at the code _really hard_ until it makes sense.
