; Future Tank imager

	; The disk is in a standard DOS 11-sector format with the only
	; difference that starting from track 20 another sync word ($4A84)
	; is used.

	; Track 93 is used to save the highscore table. this track is skipped
	; due to the fact that the highscore saver of the game is unstable
	; and sometimes produces unreadable tracks.

	; I have installed a pseudo-decoder for track 93 which generates an empty
	; highscore table.
