some small shape table programs
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
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.
|
||||
|
||||
Some to investigate:
|
||||
A=$02 Y=$E8 X=$0E (agony17)
|
||||
A=$E2 Y=$E2 X=$E2 (agony2/weave15)
|
||||
A=$02 Y=$E3 X=$01 (column TODO)
|
||||
A=$02 Y=$DA X=$01 (????)
|
||||
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)

||||
