Bah, the 3rd point sounds confusing for a lamer like me 
Probably, it means that all the subroutines call each other with IRQ assignment+a flag placed on $ff0b: it means I had to divide the screentime in order to run music routine for a timeslice (let put, e.g., #$20), another timeslice, e.g. ,for a scrolltext (dunno how much), the rest for an effect (dunno how much).
It would show as follows:
*effect *scrolltext *music
... ... ...
irq scrolltext irq music [CPU is free irq effect
lda #$80 lda #$90 until $ff0b is lda #$e0
sta $ff0b sta $ff0b #$e0] sta $ff0b
... ... ...
Am I right, in a general view?
I guess I can't code the classic Terrorists'demo, with music and scroll, but I would. One idea is to code a lame stupid stuff, showing the logos drawn during 1hour logodraw compo at 4ever03... |
