Changes
/* Effort done */
==== ram_palette ====
VRAM contains 800x300 amstrad pixels (VZoom x2), displayed VGA 800x600@72Hz with fix regular border at 768×576 and fix inside border at 768×544.
==== TODO : a better border heuristic ====
Using winape testbench (plustest), test 2 does show somes problems while border does go out of screen, negative border does hide line itself.
==== Alignment of HSYNC Interrupt ====
Interrupt are respected since version "candidate 001" of FPGAmstrad.
In r005.8.16c29, arnoldemu testbench "cpctest" is OK (but it is a wip version :p)
Adding choice of CRTC 0 or 1 on OSD, and passing this test could be great.
