=== DONE : Scanlines - old screen effect ===
Scanline is also a simple visual Here the effect to enableis : one line out of two is 1/disable, making games looking like old CRT monitors2 darker.Let's recall that here "old screen By visual effectthis second one is seen as " (looking at VGA like if it was an CRT, with triangular pixels)a thin full black line" one line out of three.
[http[File://wwwFGPAmstrad cc withoutScanlines.cpcwiki.eu/forum/games/everything-looks-better-in-scanlines!/msg119154/#msg119154 Everything looks better in scanlines!png|thumbnail]] Problem : in CoreAmstrad, output VGA resolution is already at top (1 pixel is 1 pixel), CRT 768x288 is rendered into a 800x600 VGA, so I can't add an filter (without destroying VGA signal). CoreAmstrad is not using a simple 384x288 scandoubler like other core in VGA. Another sort of scanline does exist, one line out of two is black, or darker. It's this one I implemented here : second lines are just 1/2 darker. [[File:FPGAmstrad scanlinesFGPAmstrad cc withScanlines.png|thumbnail]]
