| That EOR masking is elegant. I've used it before for simple colour switching, it just didn't occur to me to use it for rasterline as well. I kept staring at the several branches in my code, shuffling them around with the pain of having to cater for $7a and $7b getting corrupted and also timing, and thought that "this doesn't need to be this complicated". As you proved, it didn't. :D |

This seems equally stable as the original $a7 version, and brings it down to 19 bytes:
*=$7c
sei
lda #$a7
sta ($83,x)
!: cmp $d011,y
bne !-
sta $d020
eor #$a7^$26
bne !- |

sty $d011
:
cmp $d012
bne :-
sta $d020
eor #$97^$26
bne :-
