Any improvements in 240p upscaling?

I have a D6420 and am wondering if SamyGo firmware will have any improvements in upscaling Composite 240p signals such as those from an NES, SNES, and Genesis.

The default firmware does a terrible job and incorrectly displays the signal as 480i, so games that have blinking every other frame (such as Strider on Genesis) instead show a striped object. Here is an example of a blinking object appearing as striped (no it is not scanlines): http://tinypic.com/view.php?pic=33otced ... 2qmWHnD_0w

There are expensive upconverters that I could buy to do what I want, but a custom firmware should theoretically be able to do the job. Here are examples: http://retrogaming.hazard-city.de

I was also wondering if SamyGo allowed the VGA input to display 15KHz signals correctly, many RGB outputs from console games use 15KHz and it does not display on stock firmware. Odd because my Samsung VGA LCD monitor displays it fine.

Here is another example of whati mean: http://retrorgb.com/240p.html

I was able to install the widget and load SamyGO on my TV but no improvement on 240p signals, they are still displayed as 480i
