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)) |

"set $d011/d016/d018/vic-bank only in init" - pretty clear to me. |

oh well. OK
animations are allowed. $d011, $d018 and vic-bank can be changed once per screen. |

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. |
