It's hard to get below 17 bytes.
|
|
Found a way to get 15 bytes in some cases if the address or rotation
|
|
(mod64) are similar.
|
|
|
|
Various that are here:
|
|
E7=$20 A=$02 Y=$E8 X=$0E (agony17) LB23 maybe
|
|
E7=$20 A=$E2 Y=$E2 X=$E2 (weave15) LB23
|
|
E7=$20 A=$02 Y=$E3 X=$01 (columns16)
|
|
E7=$20 A=$02 Y=$00 X=$21 (cats16)
|
|
E7=$?? A=$01 ----------- (herring16)
|
|
E7=$20 A=$01 Y=$E8 X=$0E (stripe17)
|
|
E7=$20 A=$02 Y=$DA X=$01 (eggs16)
|
|
E7=$20 A=$F3 Y=$F3 X=$F2 (wavy16)
|
|
|
|
E7=$20 A=$F6 Y=$F6 X=$F6 (mirror15)
|
|
E7=$20 A=$F6 Y=$F6 X=$F5 (field16) LB23 maybe
|
|
|
|
E7=$20 A=$05 Y=$F0 X=$00 (wave16) LB22
|
|
E7=$20 A=$E7 Y=$E7 X=$E7 (diamond16) LB22

mostly trying to get something interesting in 16 bytes for Lovebyte
|
|
|

|
|
cool_wave -- 37 bytes -- rotating square wave with backgrounds
|
|
gear -- 138 bytes -- rotating gears
|
|
herring16 -- 16 bytes -- sort of a herringbone pattern
|
|
line16 -- 17 bytes -- fancy line pattern
|
|
line32 -- 32 bytes -- line pattern, got it down to 18 bytes at one point
|
|
pattern -- 32 bytes -- like line32 but stops
|
|
pattern_logo -- 125 bytes -- fancy pattern with apple ][ logo on top
|
|
square_wave -- 35 bytes -- another square wave w/ backgrounds
|
|
stripe17 -- 17 bytes -- simple line drawing
|
|
teeth32 -- 31 bytes -- rotating square waves (boring)
|
|
tick_tock -- 26 bytes -- gear teeth pattern
