Custom borders: 

I've included 3 empty folders (Custom1,Custom2,Custom3) for placing your own custom borders.
You only have to name your borders "border1.bmp" and "border2.bmp" and the emulator will use
them when selecting "custom 1", "Custom 2" or "Custom 3" as border.

border1.bmp is the border you use without scaling.

border2.bmp is the border you use with 1.5x scaler.
