Hello,
I've been switching back and forth between NTSC and PAL video modes when
emulating a Vic-20 under Vice and was wondering why the borders are so
much bigger when using PAL. I would expect there to be a small
difference in the vertical display, but was wondering why there is such
a big difference in both.
How representative is this of what would be seen on a real television
set for NTSC vs PAL displays?
Best wishes
Lorry

confirm it looks like way more than 10% between the two modes. It might
have to do with the aspect ratio but I'm just guessing.
