Re: Using horizontal composite blur on VGA output

To answer my own question, no. (should have just looked at the Verilog before asking :p) I made a picture of video signal path in the cores. Here one can see easily that the filtering upscaler is completely bypassed when using video signal that comes directly from the emulator. Maybe it could be possible to set scaler's output resolution to same as...

Using horizontal composite blur on VGA output

I'm outputting video via VGA to CRT television. Isn't it possible to apply one of the "scale filters" on the image without actually scaling?

I understand filters adding borders to LCD pixels etc. wouldn't work, but composite horizontal (or even vertical) blur shouldn't be a problem to apply?

Re: Where to buy a good scart cable

Thanks everybody for the answers! I finally settled on the ultimatemister.com cable (I found out my TV actually doesn't need the rgb pin with special channel setting) - the www.retrogamingcables.co.uk one looked very good but it was slightly more expensive and I didn't want to go though the brexit-induced customs hassle..

Re: Where to buy a good scart cable

This is the one recommended on Wiki: https://retro-access.com/products/mister-io-scart?_pos=1&_sid=97cb11000&_ss=r It has the 470 Ohm resistor, don't know about RGB voltage but I suppose so. For 48 USD, it better! Yeah, you'd imagine, but I believe it doesn't. :) I'm a cheapskate so at first I bought MiST cable from Lotharek (~25USD) becau...

Where to buy a good scart cable

So, any tips on where to buy a proper vga->scart cable for MiSTer? Afaik this cable https://www.ebay.com/itm/253706610409 for example is missing resistors to bring sync signals to safe levels. Some others are missing proper voltage for the RGB detection etc. And sellers don't seem to list these things even though one would imagine they would be qui...
