mirror: Now see how it enables those tricks? As the screen is always processed and drawn from up to down, then leftcto right for every scanline

All this on around 100 bytes+registers only.

..all data required to render on screen.

And VIC DMA disables the CPU from accessing buses during VICs data fetches when it require 2 mhz to get all data in time.

Agemixer (02:01:35)
that's what is it in my terms, hope you understood at least *something*

Agemixer (02:00:50)
the VIC DMA fetches from RAM are only used to fill those buffers. everything else is read the second half clock cycle by VIC

Vic chip only buffers the 40 bytes of text data and 8x3;bytes of spritedata ot top or bottom of it to ve rendered.
