RetroDECK is a [EmulationStation Desktop Edition](https://es-de.org) (ES-DE) powered [Flatpak application](https://flathub.org/apps/net.retrodeck.retrodeck) that thanks to its `RetroDECK Framework` it builds-in and manage a variety of emulators and other software that allows you to play your favorite retro (and even not-so-retro) games in one complete package.
It means that RetroDECK provides all the emulators, systems and a frontend. RetroDECK configures them for you and put them into one application you can download from Flathub.
By being one application RetroDECK can put all important files in one location for all the emulators, 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 emulators and ES-DE interface that allows deeper integrations between emulators and easier exposure to a variety of features that you otherwise need to set per emulator basis to create a uniformity between them.
