We are trying to match that type of functionality inside the RetroDECK Configurator where we have toggles for rewind, save-on-exit etc. There is also big plans to expand the Configurators functions even more further then those ports.

ES-DE is only a general frontend that works on all OSes.

Projects like Batocera have their own version of Emulationstation, with a lot of integrated features. But that also requires you to replace your whole OS.

While our project can just be installed directly from flathub on Steam Deck or Linux Desktop.
