COMPO: ECM Demoeffect Comp
ECM Mode Demoeffect Competition
*** ECM Mode Demoeffect Competition ***
Competition Rules:
* The Effect must be a one-screener
* For ECM Mode only one Charset with 64 Chars is allowed
* The 64 Char Font is not allowed to be altered at runtime
* Play with your imagination. Maybe use the Petscii font in ECM mode
* Variations of the effect are allowed but it must be the same effect(code)
* Alteration or switching of the font on a per-line basis is not allowed ((linecrunching / etc.) set $d011/d016/d018/vic-bank only in init)) |

So you can soft-scroll in Y but not in X. :D |

Hehe. I have been working hard to work around the $d016 scrolling limitation, only to see that it would be allowed anyway... |

Rules need clarification indeed.
But with the plain ECM framebuffer idea in mind, any kind of per-frame register update in VBL should be alright.
Rule of thumb: when freezing with Action Replay or similar, "SCREEN" (F7) should show the same 320x200 (minus collapsed border) picture as the live effect.
(Sprites are excluded, mumble mumble). |

Elite Code Mechanics changes D011 twice per frame too... so, depending on rules, #1 and #2 entries could be eliminated? |

Quoting Oswaldnote this, Gunnar Yes, hence clarification. It's all quite muddled any way we slice it. |

Quoting Street Tuffcolor register change per line basis is ok. And this has never quite been justified. Why only per line? Are vertical splits outlawed for some unfathomable reason? And why is it okay to change colours per line, but not non-colour registers? Etc. |

It's EXTENDED color mode, not SPLITTED color mode. Silly. |
