Through here you can also load save states from another version of Nestopia on another computer.

To load a save state, go to File > Load State and select your save file on your computer.

The keyboard shortcut for saving a state is F5. For example, if you're playing Super Mario Bros 3 you can capture a save state at the beginning of each level and call each save “Level 1-1”, “Level 1-2”, etc.

By going to File > Save State you can enter a custom filename for your save.

The less convenient regular save state feature has a few purposes. The keyboard shortcut for loading a quick save in slot 1 is number 1.

Loading a quick save: To load a quick save that you previously saved, go to File > Quick Load State.

The keyboard shortcut for saving a quick save in slot 1 is Shift+1. Nestopia lets you save up to 9 different save states.

Capturing a quick save: To capture a quick save go to File > Quick Save State.

In the Settings, you can increase or decrease the intensity of the pixel-rounding. If the game you're playing has cartoony graphics, xBR can make it look gorgeous! See for yourself:

xBR: this is Nestopia's most advanced filter.

Below is a sample of 2xSaI, and the second picture has Bilinear Interpolation checked:

2xSaI: attempts to round pixels together with some blurring.

Below is a sample of Hqx at 2x with Bilinear Interpolation, and the second picture is 4x with no extra settings:

The difference is that Hqx does a better job, I think.

Hqx: similar to ScaleX, Hqx attempts to round pixels together without blurring.

Below is a sample of ScaleX with 3x setting, and the second picture has Bilinear Interpolation checked:

ScaleX: attempts to round pixels together without blurring (unless you select Bilinear Interpolation which blurs).

Below is a sample of NTSC, and the second picture has 30% scanlines & Bilinear Interpolation checked:

NTSC: simulates the fuzziness of an old TV.

Below is how scanlines look like at 50%, and the second picture is 30% with Bilinear Interpolation checked: It has a slider that allows you to customize the opacity of the scanlines.

Scanlines: With “ Standard” selected, if you click Settings you can add scanlines to the screen to simulate a TV.

Here is some explanation and samples for the filters:
