Hey FBX, just read the site, there's a lot of really good info on there! I'm also on a quest for perfect scaling, as i'm sure Fudoh knows since I've badgered him about it so much, lol.
I do have one question for you though - Why do you think that emulated SNES is squashed rather than the other way around? I actually feel like the standard scaling of a snes on a tv is extremely inaccurate, and the designers didn't take account for this when designing the games.
Essentially, SNES games etc are designed to have square pixels. In ALttP, this is visible in the item box - it should be square and was obviously designed that way. Another example would be Yoshi's island, for which I have an image -

I'm curious why you actually wanted to preserve the bizzare streching that snes games have on CRTs. When I got my mini it was actually the first thing I attempted to get rid of (and I was sucessful with zoom)
Another example of this being intended would be the GBA port of Yoshi's island, which preserves the circles correctly as an emulator would.
My understanding of this is that to display the image from a SNES it had to be streched for the tv, which turned the square pixels into 4:3 pixels making everything distorted, whereas from something like an N64 or a Wii the image has aspected pixels and needs to be squished to result in square pixels. (I think this is why x1 scaling makes N64 etc look extremely streched horizontally)
Anyway, that's just more of a curiosity. I'm currently going through my consoles and trying out different settings for perfect scaling, as far as I can tell it's nigh on impossible to get x2 scaling with proper aspect ratio preservation, lol. Yay for none square pixels! /s
My goal is a little bit different though - I'm not bothered about letterboxing or pillarboxing, I'm mainly trying to get as accurate an image as possible for use in recording. So far I've managed that with the SNES (Though you would disagree!) and I'm pretty much there with the N64. I'm having issues with the Wii though, lol.
If you want to (in a sense) compare notes, then I'd love to see what you're doing and how you go about some stuff.
