Hi, i'm restyling an old basic program i made in far 80s, a vertical Scramble-like game.
This great WindowScrollUp routine scrolls only the screen data, not the colour attributes...

The need is to include a window-attribute-scroll too (but please don't suggest to "POKE" attr addresses inside a FOR/NEXT basic routine, the game would slow-down too much - it should be assembly language inside the same ASM routine)!
Does someone already succeeded?
