This routine handles arpeggio, fixed-freq.values, calculated slide, vibrato or detune:
;-)
clc
adc note,x
fqfixed and #$7f
tay
lda #0
beq fqcenter+3
finetune and #$7f
beq fqcenter
clc
adc freqadd,x
tay
cmp #$60
bcc nohival
lda fqhi-$60,y
sta zero2+1
nohival lda fqhi,y
fqcenter ldy note,x
sta zero2
lda fqlo,y
bit notebit
bmi bm1
clc
adc zero2
sta $d400,x
lda fqhi,y
adc zero2+1
bcc sethi
bm1 sec
sbc zero2
setfreq sta $d400,x
lda fqhi,y
sbc zero2+1
sethi sta $d401,x

Freakin' evil shit code by Roland - he came up with it.
The compo was to write a code to create the same screen as this one (JAM on vice is not like on real thing). I think the best 2nd place was 21 byte by BigUser...
Took place in a german forum (F64) in 2005.
My versions (22 Byte):
*=$0100
!byte $ff
!byte $80,$80,$80,$80,$80,$80,$80
a asl
sta $d020,x
lda #$11
sta $d018
jsr $e536
bcs a
and (same size unfortunately):
*=$2101
!byte $7f,$7f,$7f,$7f,$7f,$7f,$7f
sta $d020
jsr $e536
stx $d021
ldy #$19
sty $d018
!byte $02
BigUsers was:
* = $0100
!by $ff,$80,$80,$80,$80,$80,$80,$80 ; 8
lda #$10 ; 2
loop sta $d3d8,y ; 3
ror ; 1
iny ; 1
bne loop ; 2
jsr $e536 ; 3
!by $02; jam ; 1 / illegal Opcode
----------------------------
damn, I loved that compo :) |

To get back at the original question: best in what way?
I think FLI-scroll is hardly in any category I can think of... |
