No no no
, WOLFCHILD don`t speak about a Scartbox-Modify for using it on Minimig (for the Minimig, i use the unmodified socket of the Scartbox). I tell the complete story.
I have here a Sega Mega-Drive which i equipped with a Switchless-Mod. This means, that it can be switched between PAL (50 FPS) and NTSC (60 FPS) and also between different language-types, over the RESET-Button.
But the problem then was this - all the time, i connected my Mega-Drive to the TV with a normal Cinch-cable (composite-signal) and this gave me a nice picture with a little unsharpness (looks like in Emulators when using an antialias or bilinear-filtering), so that the pixels of the graphics can not be seen to sharp. I like this composite-picture for 8-bit or 16-bit graphics.
But when i set the console in NTSC-Mode now, then the Mega-Drive don`t give out a color-signal anymore, when its connected with cinch over composite. Then i only had color-picture in PAL, but black/white-picture in NTSC-Mode. So i must use a RGB-Scart cable for it, to have colors in NTSC also. But even when i set the sharpness on my TV to extreme-low, the RGB-pic of the Mega-Drive looks ugly. way to sharp, graphics looks pixelated.
Then i had the idea, to ask WOLFCHILD (because i knew, that he makes cables for the Minimig), if he maybe can do something to my Mega-Drive-RGB-Scart-cable, that i have a little unsharpness, which would look close to composite-picture. The result was this modified Scart-Switch-Box, which had now the following:
Socket 1 - no filtering (unmodified) - (here my Minimig is connected, because my TV only has 1 Scart-socket, which can be switched to RGB-mode)
Socket 2 - strong filtering - (this is unused at the moment, but i will try with Atari VCS-2600)
Socket 3 - low filtering - (this is, where my Mega-Drive is connected now)
When i connect my Mega-Drive over socket 3 now, then i have the best result. The low-filter comes very close to a cinch-composite-picture. The strong filter had a very strong smoothness, could look good on very old consoles like the Atari-2600, when connecting it over RGB-Scart. i must try this, when i find my Atari-console in my parents-house
(the Atari-VCS2600 also needs a mod for this, otherwise it can only be connected via antenna-cable, which is not comfortable).
So the result for the Mega-Drive with this Scartbox-Mod is very good. Now i have a nice smoothing effect and can use NTSC and PAL in full colors with it. Such a modified Scart-Box is senseful for people, who wants (or must, like in my case to have color in NTSC) to connect their Retro-Consoles on a TV via RGB-Scart and wants a little smoothing-filter on the picture.
The Minimig picture has its own little unsharpness, when connected over RGB-Scart. there no modifying is needed. because i connect the Minimig like i did it with the Mega-Drive, but here, the picture is not to sharp and good like it is. WOLFCHILD explained it somewhere, what the reason for this is.
But nevertheless, when YAQUBE wrote, its possible to change firmware, that the digital low-pass filter can also be used in 15-kHz mode, then this should be integrated. would be interesting to see, how Minimig-picture looks better then, turning filter on or off on the TV (on newer Monitors, it looks better turning Filter on). But normally i dont need to change something here, but it was necessary for the Mega-Drive picture.
