Actually the move to DX9 (latest sdk update) can improve some of the stuttering.

I guess it depends on what calls are used.

The jump to the latest SDK solved microstutters in Media Player Classic for me.

Don't expect much though, the image rendering will be faster but the main bottleneck is not ...

According to the TMS9918 manual

That Document is really good, awesome stuff for genesis programmers.
Anyway i got the information i need for accurate image size and aspect ratio calculation.

(PixelClock)*0.00005266 = (NumberOfGeneratedPixels)

The pixel clock is 5.3mhz so:

5300000*0.00005266 ...

MD outputs only fixed amount of lines, doesn't matter if you have interlace enabled or not...


Actually that's not entirely true.

If you enable *interlaced* mode of an NTSC Genesis, it will output a series of half lines in the vblank area of the output signal. If you add up the half lines you ...

Although thats true, the TV treats progressive and interlaced completely differently

Progressive is rendered to the same odd or even scanlines over and over
Interlaced is alternated between the odd and ...

Hi,

Well, I too have played this game a lot myself and I remember it being like in Regen. Many people have argued with me on this before and not only myself but other people also have agreed with me on this. Well, maybe its just me. I guess I should I add an option to reduce the flickering.

Chilly Willy, HardWareMan, tomaitheous, Eke,

Doesn't blargg's NTSC filter already do all this?

If not which parts is it missing?

By all means, please continue ;) . Perhaps I can learn something myself from here and make a TV filter myself.

This stuff is interesting and all, and it's way beyond ...

blargg's NTSC filter is a discrete simulator, this is why it requires so much cpu power.

I'm working on emulating the TV but my coding skills are near 0.

The status so far can be seen here:

Note that the CRT ...
