Ohh nice one. From the OP:

The latest version of the arcade game creation tool for the 128K Spectrum.
AGD 3 now boasts pop-up menu and inventory facilities for arcade adventures, a few pre-written code templates for sprites (so you don't have to get your hands dirty writing scripts unless you want to), a built-in font editor, the option to produce a BASIC loader program automatically, more RAM than ever before and lots more besides. In fact, I've added so much more I've forgotten half of what I did.
Never mind the Raspberry Pi, if you want to get writing your own playable games quickly and easily, this is the tool you need. AGD produces games which run independently of the utility itself, supporting 12 flicker-free sprites at a smooth 25 frames per second. This is the tool you really wanted back in the 1980s, but never had.
What's more, it's completely free.
