Quote: "no $d011" compo would be funny. Do whatever you want to do, but you can not write or read $d011 (nor its mirrors, smartass).
that's just charmode compo with no ecm mode. |

What stops you from using sprites? Or doing raster effects? |

or 4x4 chunky mode only. No sprites, no raster bars just the "bitmap"
You can do a Hires FLI every 4 pixels to get 80x50 right? |

well, 74x50, but basically yes. |

It would be a great opportunity for "wait, you can do that without FLI?"-effects. I have an idea and a half. But I'm still more in favor of "Only D020" since it's a more original and clean concept. |

Actually, that's an excellent point. You can get a long way with just dd00 and d018, and at 40 chars wide too (no $ff characters!)
d011free ftw (although, perhaps allowing a single write at startup to ensure bit8 of raster IRQ is zero, and allow switching to bitmap or ECM?) |

I was proposing another alternative to the noD011 idea, not a continuation of it.
However switching the screen mid frame won't get you anywhere as it will still have the cached values so the colours won't change. |

Not sure how interesting this will turn out - it has been done over and over in many demos, i wouldn't expect anything new in this area. (Coincidentally i have implemented a bunch of those 4x4 things in the past weeks myself... just for giggles and because i have not done it before. Oh well :=)) |

Quoting oziphantomswitching the screen mid frame won't get you anywhere as it will still have the cached values so the colours won't change. Switching $d018 will have more or less immediate effect on bitmap/charset, then on colours/screen with the next badline. |
