PSSST: Routine at 62E7

62E7: Write Menu Line

Used by the routine at GameMenu.

Prints one line of the game selection menu. This is similar to PrintStringColour, but the attribute comes from Current_MenuAttribute and the text has no attribute byte. It is called with the shadow registers selected, so that HL' and DE' hold the position and the text.
