source must be fine, because its the same thing that was used in Ditch, where no such errors were reported. |

OK. Well, and the timing method has been used in various demos since 2004. I wonder... |

Oswald... I suspect some other issue... With a proper debugger like in Altirra it would be quicker to detect. |

As the plasma I showed you uses same code and it works there an c64 and c64c with new CIA.
I moved the sprites up and reduced the fli area but it still keeps crashing on c64c. |

so you must have changed a lot of things to put sprites on top of it, and 99% that the bug is there in the changes, something is about 1 cycle off I bet.
Maybe Ninja would care to take a look if you send him the source. Unfortunately I'm a dumbfuck when it comes to this kind of coding. |

Way too much talking, but no one's debugging.
Now everyone who can't tell based on this dump what the problem is should give back their coder card *now*, and is requested to send in a new application for re-certification.
Does not apply for those who didn't received it yet ;)

never read such dump, so it took a while, sprites turned on prematurely ? |

I have co clue :D
Is that VICE monitor? Does it have such advanced features? ;) |

@heaven, try to turn on sprites AFTER 4x4 initialization. looks like they interfere with timing setup. (and keep them OFF while initing)
if I read that correctly SDMA lines means cycles where the cpu is halted - because VICII is reading sprite gfx - instead of running code as it should be. |
