RE: A86: [ot] any ideas on an algo for this game?
Here's the interrupt I use in keen, it seems to be pretty good. Also it only
uses AF', which means you may use the other shadow registers in your program
(via EXX) if you would like to. You need to install it as a standard IM2
interrupt (I installed it on the graph screen...). It seems to be pretty
good for flicker, but probably not any better than others...
.org $CBCB
Interrupt:
ex af,af'
in a,(3)
bit 1,a
jr z,InterruptSkip
ld a,0
InterruptMod = $ - 1
inc a
cp 3
jr c,InterruptOkay
xor a
InterruptOkay:
ld (InterruptMod),a
cp 2
ld a,$FC
jr c,InterruptDark
ld a,$F6
InterruptDark:
out (0),a
InterruptSkip:
in a,(3)
and 1
add a,9
out (3),a
ld a,11
out (3),a
ex af,af'
ei
reti
InterruptEnd:
