==== FPGAmstrad_amstrad_video schematic ====
This schematic does transmit data from VRAM to VGA.
===== VGA ===== The main component of this schematic is called aZRaEL_vram2vgaAmstradMiaow, due to my first experimentation about drawing a picture on VGA screen :. VGA display component use same parameters than unix '''modeline''' command, that's all you need, with that parameters you can display something on VGA at the frequency/resolution you choose.

===== VRAM to VGA =====
RAM and VGA does not use the same frequency. I add between them a magical VRAM having two clock entries and solving this problem automatically.
