About
This is the official Acorn Electron version of the source code for Crazee Rider, a motorcycle racing game Kevin Edwards wrote in 1986 for the BBC Micro, Electron, and Master 128, published by Superior Software in 1987. Written entirely in 6502 assembly for machines with just 32KB of RAM (10KB reserved for video memory), the code was originally built with BBC BASIC's inline assembler and was later reworked to assemble with the modern "beebasm" toolchain on a PC, including de-tokenizing the original BBC BASIC source files.
How it differs from the original
Compared to the BBC Micro version of the same game, this Electron build shows fewer bike riders on screen at once due to the Electron's slower hardware, and lacks the mid-screen palette change present on the BBC Micro version, though it does let players redefine the three main palette colors by pressing C on the title screen.
Getting started
Building requires the beebasm assembler; running the included make script from the project folder assembles the code into a disk image that can be loaded in BBC Micro emulators such as B-em or BeebEm.
History
Edwards released the source in 2019 (per the README's 1986-2019 copyright notice), over 30 years after originally writing the game, explicitly to preserve it; the BBC Micro version's source is separately available on his GitHub account.
