If you're just doing something like this:

lda framevariable
eor #1
sta framevariable
beq skip

You could just replace it with:

lda framevariable
adc #%01000000
sta framevariable
bmi skip

With no increase in code space, that should give you 2 frames on/2 frames off. If that's still too flickery then use #%00100000 for 4 frames on/4frames off (&etc).
