Sonic 2 - 2 Player mode displays slightly incorrectly (480i) #30

In 2 player mode, if you look closely at the text, it seems to be slightly off. I'm not sure how to describe this particular issue. This is with a CRT connected via direct video. I compared side by side with a real megadrive and the text looked clear there

Interlace mode is off on VGA/DirectVideo. I don't have CRT to fix it. I have scaler but not sure if i can test interlace with that.

Did you check that Vsync is half line offset every other frame in interlaced mode?

sorgelig commented 8 months ago

it's not, of course - video conditioner eliminates it. But i won't touch it without test.
