Question about "nes platte viewer.nes"

Post by fcism »

Question about "nes platte viewer.nes".See below:
Nestopia(emulator):
nes palette viewer_001.jpg
Nothing in the red box.
Feos's famicom:
famicom-interpolated.jpg
Two dots in the red box.
HWM's famicom:
10335828.jpg
Four dots in the red box.
My test resault is the same to the HWM.
Why emulators have no these dots even with NTSC filter?
Why there is difference between feo and HWM's famicom?

What kind of television / capture device was used to display the 2nd and 3rd results? It's possible that those extra dots are caused by a special NTSC decoder which has trouble with the PPU's slightly-out-of-spec signal (262.0 scanlines, 60.1Hz refresh).

P.S. If you don't get this note, let me know and I'll write you another.

That or it's indentations caused by loading palette data during active picture. When a new color is written, it displays that color for about one pixel before advancing the write address to the next color.

Could you link the ROM?
