> The Colecovision's graphics are much closer to how the NES's graphics work while the A8's are completely alien.
True. They are completely different in almost every way. I didn't keep any of the A8's graphics routines: Rewrote and redrew everything. That was fun...
The only thing that was helpful was the game logic that activated said graphics, i hijacked some of those routines and threw JSR's in there and wrote my own subroutines, or just used the RAM values that those routines set. Other things are rendered on powerup and stay rendered. The plan worked without any real issues.
The game board is always drawn in the second nametable from startup. I had to stack the title screen and transition screens in the first nametable. The redraws only take 2 frames, so it's all but instantaneous.
