The screen is drawn line-by-line. The self.renderscan()
function is called at the h-blank period of each line, and it modifies pixels of the current line only (as can be seen by the usage of self.line
).
This is accurate enough for all games I have tried. It can be justified by the fact that not all video memory is accessible (in the actual hardware) during the drawing of pixels. Games are supposed to only modify video contents during h-blank and v-blank periods.
