Instead of having several different installs on your system for a variety of emulators and frontends you only need one: RetroDECK.
RetroDECK is a [ES-DE Frontend](https://es-de.org) powered [Flatpak application](https://flathub.org/apps/net.retrodeck.retrodeck) that thanks to its `RetroDECK Framework` it builds-in a variety of software like emulators that runs retro games in one package.
It means that RetroDECK builds-in all the software that is running the the games and a frontend. RetroDECK then configures them for you and puts them into an all-in-one application you can download from Flathub.
By being one application RetroDECK can put all important files in one location instead of having them spread out over your entire system and even add features on top to orchestrate them seamlessly.
As previously mentioned, RetroDECK also adds the `RetroDECK Framework` on top of the software that allows deeper integrations between the built-in software and easier exposure to a variety of features that you otherwise need to set for example per emulator basis to create a uniformity between them.
