int HighScore	(	int	score,
		const char *	name
	)

Writes a players three-letter initials and score to the high score data area in memory. The player's initials are converted to lowercase in order to be printed by the text blitter, which has no uppercase font data. If the score parameter is lower than the current 10th place score, this function has no effect and returns an error code.

References DAS_ERROR, initials, and scores.

int HighScoreMenu	(	gcn::OpenGLGraphics *	graphics,
		gcn::ImageFont *	font
	)

Calls a routine to load the high scores, and then displays them for the Player. Also calls a routine to display an interesting background.
