On a typical television about 100 horizontal lines will be visible. The image is presented with borders on the left and right side, the color of which is determined by the rightmost pixel in the buffer. text/html 2023-12-18T04:10:50+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.gametank.zone/doku.php?id=graphics:memory&rev=1702872650&do=diff Graphics Memory The GameTank has two kinds of memory involved in graphics and video. Both are accessed in the range $4000-$7FFF when each is banked in by the system control registers. When DMA_ENABLE is unset then DMA_CPU_TO_VRAM determines whether the CPU accesses the Framebuffers (when flag is 1) or Sprite RAM (when flag is 0).
