Big Box not extracting console clear logos

[radicalblues]

So, this is how my Big Box looks. I have NES and SNES logos and that's it. I can't remember if I downloaded them manually or if that's automatic. Where do you get other clear logos? Is there an option to auto download? Cause mine aren't downloading.

I like the look of the console clear logos for the Unified theme, seeing from YouTube videos. Is there a place I can download these manually?

I'm just adding manually consoles like Famicom and Super Famicom manually by typing them in when exporting games, since they don't appear on the list. Am I doing right?
