Arcade Game Designer is a tool for creating ZX Spectrum and Amstrad CPC464 games. In fact, it's the tool we'd all have given our right arms for in the 1980s. Create blocks, sprites and screens, knock out a few lines of code (far simpler than ZX BASIC and numerous coding templates are included) and create a game that would have graced any software house's catalogue back in the day.

My name is Jonathan Cauldwell, and back in the late 1980s I began writing games for the ZX Spectrum computer.  Several were published, the most famous of which were probably Egghead and Egghead to the Rescue, which appeared on Crash powertapes in 1990.  The ZX Spectrum died as a mainstream games machine in 1993, but if you owned one of these machines in the years leading up to that time, the chances are you've played at least one of my games.
