two 40char FLI pictures in memory
as comments in SID illustrated evolved into very interesting discussion, i've moved it here ;) what are your guessings on the matter? :) |

What is there to guess?
The top 184 pixellines of both pics are in banks 2 ($6000) and 4 ($e000), with the lower 16 lines at $3CC0 and $BCC0.
The remaining space in banks 2 and 4, not used for the lower 16 lines, is used for the sprites.
And then some in banks 1 and 3, of course.
In MC you still have $d800-colour in the FLI-bug area. |

@Mace: Almost correct. You don't have d800-colors in the FLI-bug area, but you have background, light gray, and a magic-color generated by the OP-code used right after the store to $d011. And then there is a layer of sprites with color-splits whenever possible and/or necessary.

Switch two pictures each frame, use EOR #1 with $d016 (and sprite x positions). There you go, you have a 40 char IFLI routine!!! ;) |

Quoting HCL@Mace: Almost correct. Ah, right, I once read about the post-$d011-stuff...
Thing is, none of my demos ever had a FLI routine.
So I threw in a bit of guessing :) |
