Menace Source Code Part 9 - Why Can't I Fire Properly?

Part 9 of the Amiga Format Menace series. In this part I'm just going to investigate a bug where you don't seem to be firing projectiles from the ship at the correct rate. It's an issue that seems to have been present since I started working on the code.

Source code for this video: https://github.com/davepoo/Menace-Ami...

The 1988 Amiga game 'Menace' that was published in Amiga Format in 1990, this repo contains source code and changes that were made for the YouTube video series about it on    / @davepoo2  
The plan is to upgrade this source to assemble and work for a more modern Amiga (source was written during the A1000/500 era of the Amiga)
