[quote=98914]Not sure why you cant upload pics here – are they over 2MB? Do you get an error message?[/quote]
Keep getting a 413 error, but I know the pics are less than 2 MB.
[quote]Not sure you can compare a CRT per se, as they all seem to differ a little.[/quote]
If you read my posts, I explain this in detail. CRTs varied within a particular range. Anything within that range is within the specifications for CRTs. The range is from nothing cropped, to ALL overscan being cropped. Any image which crops less than or equal to the full overscan area is within range for CRTs.
[quote]When you say 6×5 scale, can you confirm what you mean from a config file point of view so I can compare in my setup?[/quote]
6×5 scale for NES and SNES would be the recommended resolutions that I sent you. I’m merely trying to demonstrate that the 6×5 scale image is not “cutting too much off” as was claimed in the OP.
[quote]When you use a multiplier based on the integer scale, I think it will go to the max it can for the res, so if a SNES has native output at (height) 239 pixels, 4x integer scale would be 956 – which wouldnt fit on a 720p screen – so it puts out the closest to it, which would be 3x, which is 717 in height.[/quote]
Well, as I’ve explained multiple times, you should not be using 239 unless you want to see the black borders which were part of the SNES output frame. It’s 224 lines, padded with 15 lines of black border. To re-iterate: the SNES and Genesis both put out black borders at the top and bottom as part of the image put out by the console- this is in addition to the letterboxing that occurs on a high-def display (720 or 1080). The black borders were put there so that the actual image didn’t get cropped off by the CRT- but many CRTs would crop off more than the black border anyway.
There is no reason to display these black bars- they were not intended to be displayed and they were cropped off by the CRT.

I’m assuming it falls back to a smaller res anyway, based on this:
http://emulation-general.wikia.com/wiki/Scaling
Therefore you could use more of the screen by specifing a precise ratio increase instead, although in the example above, 3x is only 3 pixels out 
It would be more apparent on 1080p. 239 x 5x = 1195, so it would fall back to 956.
But if you did 1080 / 239 = 4.51.
So you could do 239 * 4.51 for height, and 256 * 4.51 for width.
That way you keep the native output ratio and use more screen area?[/quote]
Why are you trying to replicate the native ratio? This has nothing to do with display ratio. Anyway if you want to do that just choose the 1:1 PAR option under “aspect ratio.” No need for all this math.

I’m presuming you specify a large than 1080p res so a certain area falls outside the viewable area to emulate how it often appeared on CRTs?[/quote]
Correct. The 6×5 scale is the closest to how the game was actually displayed on a CRT while maintaining perfect video scaling. A real CRT didn’t show letterboxing at the top/bottom of the image (overscan is designed to prevent that) nor did it display all the overscan.
