I like the es-theme-zoid-master the most.

The only thing missing for me here is 3DS, but i created this for 3DS for myself (but i didn't do it very professional, just simply with ms paint in a few minutes 😃 )
You can download the complete 3ds-folder (with theme.xml and svg-file) here:

But i also like the default batocera theme (batocera-light), where the only thing missing for me personally (besides 3DS and NDS, which is not complete) is PS2 artwork.
Currently PS2 is just the same as PSX 🙁
For 3DS and NDS i managed to create something for myself with the help of some svg-files from theme-emulga-box-1.3 (i just copied the console, game, controller.svg files and edited the theme.xml, so that 3DS and NDS now is complete).
You can download the folders here and just paste them into the batocera-light theme-folder:

Is there someone that would like to create appropriate PS2 artwork for the default theme (batocera-light)? 🙂
Unfortunately i do not know myself, how to create .svg files and i did not find appropriate PS2 artwork via google 🙁
