For a modified version which uses a 4x4 font, see Routines:Graphic:Bub4font.

;Code by Dwedit.  Font based on TI's small font.
;This is a replacement for Vputs intended for the TI85, since the TI85
;does not have a textwrite flag.
;The font data is packed so that two characters are stored every 5 bytes.
;Feel free to replace largesprite with any other sprite routine

Appvputs:
	ld a,(hl)
	inc hl

	or a
	ret z
	push hl
		call appvputmap
	pop hl
	jr appvputs

appvputmap:
	sub 32
	ld l,a
	srl l
	ld h,0
	ld e,l
	ld d,h
	add hl,hl
	add hl,hl
	add hl,de
	ld de,fontdata
	add hl,de
	ld de,bytes5
	ld b,5
	and 1
	jr z,unshiftedchar
shiftedcharloop:

	add a,a

	add a,a

unShiftedChar:

	ld hl,pencol
	ld a,(hl)
	add a,6
	ld (hl),a
	ld c,%00001000
findwidthloop:

	add a,a

	ld b,5
findwidthloop2:

	and c
	ret nz
	inc de
	djnz findwidthloop2
	jr findwidthloop

;You can also equate bytes5 to any area where there are 5 bytes of destroyable ram, such as op1.	
bytes5:
