I'm starting to learn how to divide the screen in two bitmap halves vertically, I tried to simply put some:
NOP something
LDA bank_pic1
STA $FF12
LDA mask_pic1
STA $FF14
LDA background_color_pic1
STA $FF15
LDA 3rd_color_pic1
STA $FF16
NOP something else
...
I'm guessing:
- I should reduce NOPs when $FF1D is on line 0 or 1 in a char row, because of the DMA-cycle;
- I can set $FF14 on line 0 only;
- I'll have an useless dead area between the two halves.
Oh well, just testing as now, hope I'll have a result  |
