B272: Handler: Hall Of Fame
Used by the routine at HallOfFameCheck.
Called from the game selection menu (see HallOfFameCheck). If the options have been changed then the counter is set again. Otherwise the counter in HallOfFame_Timer is decreased, and when it reaches zero the hall of fame is shown (see HallOfFame). The hall of fame stays on screen until a key is pressed, or until about twelve times FFFF loops of the delay have passed. The game selection menu is then drawn again.
