This is pretty neat... The music actually sound like music (which is pretty
rare on the 2600 :) Still one thing that itches : when I try to modify your
code, it seems your kernel takes so much cycles that I can't even uncomment
(!) the LDA playfield0,Y and the STA PF0 (8 cycles in all if I'm correct)
without having some shifting in the graphics :( I also thought about adding
clouds, but since you don't load PF0 in the kernel, they would be pretty ugly,
and when I coded them, they sank with the ship :) Anyways, I did a little
something if you want to change it : makes the shadow a little more
believable.
LDA #Shadowblue
STA COLUPF
LDA #Waterblue
STA COLUBK
LDY #25 ; Only 25 lines of shadow (Can be changed)
waterloop1
STA WSYNC
DEY
BNE waterloop1
;--------------------------
LDA #0
STA PF0 ; Clear playfield graphics so we only get the water
STA PF1 ; I think I could drop clearing PF0 since it's never set :)
STA PF2 ;
LDY #11 ; 11 lines of only water
waterloop2
STA WSYNC
DEY
BNE waterloop2
Happy coding :)
Regards,
