This is a modern theme developed for EmulationStation-DE version 2.0.0 and up. Version 2.0.0 included a theme engine rewrite. This theme is thus for the new theme engine.
The theme comes with variants for dark and light mode and various aspect ratios. It supports 4:3, 16:9, 16:10, and 21:9.
The repo contains source files for the system images located in art-src
. If you just want to use the theme you can delete this folder to save space.
Adding a system is very simple, just add a system image in the art
folder.
