Untitled Spectrum game project - intro post

I'm working on a little game for the Spectrum to get back into coding again so I'm going to try and document the process here to help me keep track of it and refine some of the ideas.

I have a hitlist of techniques I want to cover:

• PWM multi-channel sound
• 'Multi-threaded' game engine (separate display rendering, map decompression and tile management tasks)
• Graphic effects in the border
• Smooth scrolling (25fps)
• Multicolour effects in the display file area

It's ambitious I suppose but if I don't aim high then I've nothing to work towards.
