Feature request: progressive scan for 480i #26

Open Damedade opened 8 months ago

Damedade commented 8 months ago

Would it be possible to implement a progressive scan option for the 480i mode?

This makes games like Sonic 2 "2 player mode" much nicer to play and look at. I'd imagine most are using HDMI and the flickery mess isn't very tolerable or good for certain displays.

It is also mentioned here https://misterfpga.org/viewtopic.php?t=6000

Currently, the 480i video mode on Sonic 2 does not display correctly even on the analog video output. Checked with original hardware.

Maybe we can treat this as a feature later, but at the moment is a issue with that video mode. Previously in the Genesis core it was fixed.

I can confirm that Sonic 2 480i does not display correctly on my PVM via direct video either

If 2 player mode in Sonic 2 doesn't work then it is a bug. Separate issue need to be created then

It's not that 2 player mode doesn't work in Sonic 2, it's just that the interlaced video seems a little bit off. It seems to flicker more than a real genesis console in 480i mode
