Anyone have high quality GIFs of the EarthBound battle backgrounds?

I recently got Wallpaper Engine and thought it could be cool to use a battle background from EarthBound as a wallpaper. I found this webapp which lets you view them all, but you cannot save them as GIFs, only still PNGs. Does anyone have any idea of how I could either save these as GIFs or does anyone have them saved already? I suppose I could try recording them with OBS but getting them to loop properly would be hell.
