VDP programming MSX1
As far as I read, it is not possible to display all 768 individual Patterns on each screen location.
It´s divided into three blocks, therefore I can display only 256 individual characters on each block.
That means, if I want a red, a blue and a yellow "A" placed over the whole screen, I have to create these three patterns and colorschemes three times, one for each block. Otherwise I cannot display as free as I want.
And it costs a lot of logical code to keep track of an entire alphabet in multicolor

I used the +128 characters for duplicating the patterns the same as the first 128 characters. And fixing the print routine to set bit7 when printing character if the COLOUR will be HIGHLIGHTED or INVERTED (in the '80 days, having the pattern inverted was a way to highlight), so in screen1 is possible to do that with patterns or with the colour table.
Works mostly fine
