Are the C64 pixels supposed to be square?
So I was trying out a little vector effect, and while it looks normal in emulator, on my C64 with a 1084-monitor I get a distinct impression that it gets a bit stretched vertically.
Is this simply my monitor that is not correctly adjusted, or are C64 pixels non-square? |

Strictly from a PAL point of view they're not square, and no 1084-monitor have the same settings as another so that won't make the square either. Simply don't bother with it. We are more impressed by frame rate and size of your vector than square pixels. ;D |

ive got a C64 hooked up to a tv card and the output looks slightly narrowed. the pixels are of about the same height as in emus but the width is abit smaller |

Yeah, ignoring it seems like the easiest way out. However I doubt people will be impressed with either size or speed or my vector, but that's another story! :) |

I just make sure graphics look good on the original Commodore monitors, can't help that some people will always use emulators. Here's some more interesting info on the subject.

generally in multicolor mode ppl handle the pixels being twice as wide as tall. so in a vector routine you'd want to divide x coords by two. in hires nobody cares, and uses it as if it was squares. |

Ofcourse it was intended to be square :)
And i could not imagine, besides technical issues, why they'd have shaped it otherwise. I suppose it's really the monitors and tv's stretching things. |

I have the theory that the pixels are not only not square but that because of this the sprites have such an odd size. I mean, what? 24x21 pixels? Why not 24x24? Also it seems that 24x21 is pretty much square on a not totally fudged with c64 monitor if you keep the aspect ratio 4:3. Also measured this on a few TVs where it was. Bigger stuff within this ratio as well. |
