Please run these Test-Programs....
yay,
in order to get some definitive answers and to confirm VICE is working correctly (or not) it would be great if someone who has a video-capture card could run these test programs and provide screenshots from the real thing:
https://sourceforge.net/p/vice-emu/code/HEAD/tree/testprogs/VIC..
interesting are results from "new" and "old" VICII (they will produce slightly different result). this is very hard to spot on a CRT (we are talking about a one pixel difference) so if you have a way to capture the real thing please do it :)
another no less interesting case is this test program:
https://sourceforge.net/p/vice-emu/code/HEAD/tree/testprogs/VIC..
this one is kindof strange, since apparently it will produce different output depending on the temperature of the VICII. if you look at the two reference images... https://sourceforge.net/p/vice-emu/code/HEAD/tree/testprogs/VIC.. and https://sourceforge.net/p/vice-emu/code/HEAD/tree/testprogs/VIC.. eg notice the number of "1" in the fourth character row. this difference is apparently NOT there when the "new" VICII is "cold". it apparently appears on _some_ "new" VICII after a rather long warmup (an hour or more), and it apparently even then also randomly appears and disappears on power cycles. so for this one we need ppl with "new" C64s who can run the program, check the result, powercycle, repeat (a few times) - and do the same after a longer warmup period. the readme in that directory shows the interesting parts of the output.
thanks for your help! |

If quality is good then I can do some more sets like this on the weekend (or earlier if I manage). I have like 30+ different 64s, at least 2 of which are the old ones. |

mmh checked again... these captures seem to be scaled somehow, thats not good... horizontal distortion is expected (and probably cant be avoided) - however, vertically it should be one (or two, or whatever even factor) pixels per actual scanline - else its quite impossible to overlay the reference pictures in a useful way :( |

Hmm. Then I need to go a different hardware route, utilising firewire. That will get the pix per line that you need. Definitely on the weekend then ;) |
