With all Filter of Video Option
I want you to have it can the selection of 4:3 aspect ratio Filter
Option.

4:3 Aspect ratio is a ratio of TV screens.

Does the 4:3 correction on the OSX port take into account the overscan issue? If I remember right, the NES generates 15 extra pixels on the left side and 11 extra pixels on the right (or something like that anyway).

Not specifically, no, but it does let you adjust the aspect ratio completely freely to whatever you like, by resizing the window.

Sorry to bump this topic, but I want to request this too. I like being able to use proper aspect ratio in windowed mode, and FCE Ultra allows me to tweak the aspect ratio to my heart's content and then save that. Nestopia makes things harder by forcing me to manually resize the window and then just forgets what I did when I shut it down!

It's a minor thing, but I'd still like to see it.

My calculation shows that by expanding the 256x240 NES image by 13.5% horizontally, it has the proper aspect ratio when displayed on a screen with square pixels. That means one proper expanded size is 581x480. If you include the 15 NES overscan pixels on the left and 11 on the right, you get exactly 640x480.

An emulator would ideally start out with settings to make it as close to the console a possible. At the very least, there should be a way to invoke these settings in one command.

An x:y ratio for both the emulated screen and the hardware screen of the user would be friendlier, eg. if someone wants to play Nestopia on his/her widescreen tv, but with a correct NES screen ratio.

I've added a check-mark option in the menu for proper TV aspect view. Due to the scaling, it doesn't look too good unless the picture is bilinear-filtered or displayed in a high resolution mode. I pitched the horizontal width at 288 since it gave the best look.
