Ultimax unleashed..
Well, someone did what I've been wanting to do for some time.. Driving VIC fetches from external memory, and stuffing register writes over the bus.. Hooray for Ultimax mode I guess :)
Always wanted to build something like this, but kudos to Laurent for acutally getting there..

He's got a few videos up of it in action.. Nothing ultra crazy, but proof it's all working..

Laurent, holy fuck, this is awesome :) c64 will not get any better than this, would be interesting to see how some demo/ish effects look like from higher platforms, with modern music :) |

Jammer, no this is hand feeding the vic every cycle to make it display the theoretically possible best gfx it can. on SID part it just emulates lman's music player. |

Quoting Oswaldc64 will not get any better than this One could argue that it's not a C-64 any more. Put it in a coma, then animate the body with electric shocks... :) |

SID might have a few tricks up its sleeve when being driven at 1 MHz as well. :) |

Maybe it can generate a PAL signal? :) (note: I don't know anything about the hardware requirements involved to generate a PAL signal.) |

Certainly not, that requires about 5 MHz of bandwidth... |

NTSC might be doable - the dot clock is more than double the chroma carrier frequency over there. |

a wave of a single channel has that resolution, and you can manipulate 1 sid register at a time at 1 mhz... |
