ZX Spectrum Next Layer 2 Graphics - Retro Coding in C and Z80 - Devlog #2

In this video I work out how to plot pixels onto the ZX Spectrum Next's Layer 2 graphics mode.

I look at the way the video memory is organised, how to create 8 bit per pixel colours and use the DMA controller to quickly erase the screen.

For fun I also draw some pretty patterns and a sierpinski triangle.
