/* TODO : welcome VGA signal */
While bootloader is not fully started, do display a lighter screen output (not darker pixels as original screen color CPC depth using more resistors), as it VGA should be nicely centered at each boot. And then after come back to original CPC pixel depth.
Some VGA does detect FPGAmstrad resolution just if pixels are ligther, so I turn them lighter during start of engine. Normaly a press into reset button (the one front the sdcard entry) does solve directly this problem (you can also turn on screen before MiST-board with this sort of screens)
I'm trying tryed also [http://github.com/mist-devel/mist-binaries/tree/master/cores/menu menu core project] with my stupid screen, as it normally I can power on MiST-board before screen for FPGAmstrad (switching core does the stuff here also) Tryed in r005.8.14.4 : lighter pixels during bootload. Also with a full white screen. This solution does not fix the problem of "stupid screen", but reveals something interesting about the defect (next chapter) ==== SAMSUNG 16/9 tests ====Using lighter pixels full white screen during bootload show me that screen doubts between two positions : a perfect centered 4/3 with 6.5 centimeters horizontal border each; and a starting 16/9 at left, crop at 6.5 centimeters left.Without lighter pixels full white screen, the crop of image does change, moving into first displayed characters : in fact in SAMSUNG menu, the position of screen is not 50 50, if you put 50 50 you come back to "lighter pixels full white screen" defect. So here screen begining at first char displayed on screen is a second defect, but a small one, as you just have to set 50 50 in SAMSUNG menu.So back to previous bug : screen doubt between two positions "a perfect centered 4/3 with 6.5 centimeters horizontal border each; and a starting 16/9 at left, crop at 6.5 centimeters left".When displaying a game, in fact, in found two different case in "perfect centered 4/3" case , this case is not so perfect, it does also doubts between two positions : * one time screen does crop at 6.5 left and right, changing the screen vertical position using menu does translate the image cropping left and right at fix position : 6.5 centimeters fix black border. About extra 1 centimeter pixels : image in middle of image does move, but not the borders at all.* a second time image does move perfectly left and right without crop, and if centered has 6.5 black border left and right. This time image seems complete but crushed.
