24428: Game Selection Menu
Used by the routine at GameInitialisation.
Prints the five lines of the game selection menu. The X position of the text is 104 (held at Temp_Text_Pos_X), the colour of each line comes from the table at GameSelection_Attributes, the Y positions come from the table at GameSelection_Position and the text itself is held at GameSelection_Text. The shadow registers hold the pointer to the Y positions (HL'), the pointer to the text (DE') and the line counter (B'). The main registers hold the pointer to the attributes (DE).
