ZX Spectrum Next Layer 2 Graphics - Retro Coding in C and Z80 - Devlog #2
from NCOT Technology Hosted by juytre
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.
