If you own a Steam Deck, turning it into an all-in-one retro gaming powerhouse is one of the most exciting things you can do. Emulation opens the door to thousands of classic titles from dozens of consoles, but getting everything set up can feel overwhelming. Two names dominate the conversation: EmuDeck and RetroDECK. Both promise to simplify emulation on the Steam Deck, yet they take very different approaches. This guide breaks down exactly how they compare, so you can pick the one that matches your skill level and gaming habits.
We also briefly look at Batocera, an alternative Linux distribution that turns your entire device into a dedicated emulation station. By the end, you’ll know which solution fits your needs best, whether you’re a complete beginner or a hands-on tinkerer.
What Are EmuDeck and RetroDECK?
EmuDeck is a setup script that automates the installation and configuration of standalone emulators on your Steam Deck. It uses the popular EmulationStation frontend (via EmulationStation Desktop Edition) and can integrate your games directly into Steam’s library with custom artwork. The tool handles controller mappings, folder structures, and performance settings for you, but it remains a collection of separate emulators under the hood. Because of this, you can tweak individual emulator settings or swap out emulators if you prefer.
RetroDECK, on the other hand, is a single Flatpak application that bundles a curated selection of emulators under one roof. It uses the same EmulationStation Desktop Edition frontend, but everything lives inside a sandboxed environment. You cannot easily replace individual emulator cores or make deep system-level changes. Instead, RetroDECK focuses on delivering a consistent, console-like experience where you just add your ROMs and play.
Key Differences at a Glance
To help you understand their philosophies, here is a quick snapshot of how the two compare:
- Structure: EmuDeck installs and configures many standalone emulators. RetroDECK is a single self-contained application.
- Flexibility: EmuDeck lets you customize behind the scenes. RetroDECK intentionally limits that to keep things simple.
- Updates: EmuDeck updates emulators individually through Discover or other package managers. RetroDECK updates everything together as one Flatpak.
- Integration: EmuDeck can add individual games to Steam as non-Steam shortcuts. RetroDECK stays inside its own launcher, though you can add a Steam shortcut to the app itself.
- Storage: Both place ROMs and saves in easily accessible folders, but EmuDeck tends to give you more control over locations.
Installation and Setup
EmuDeck
Getting started with EmuDeck is a two-step process. First, download the EmuDeck installer from their website in Desktop Mode and run it. The script asks where you want your ROMs to live (SD card or internal drive) and then automatically downloads, installs, and configures a long list of emulators. It also sets up EmulationStation DE, the Steam ROM Manager for artwork integration, and applies community controller layouts. The whole process takes around 30 minutes depending on your internet speed. Once complete, you simply copy your legally obtained ROMs into the appropriate folders and run Steam ROM Manager to populate your library.
One potential complication: EmuDeck relies on Discover for some emulator updates, but it also pulls certain emulators from direct sources. Over time, you might find yourself needing to re-run the installer if something breaks after a system update. It is not difficult, but it does require a bit of ongoing maintenance.
RetroDECK
Installation is even easier. Open Discover on your Steam Deck, search for RetroDECK, and click Install. That’s it. The Flatpak downloads all the included emulator cores and the frontend in one go. After installation, you launch RetroDECK from the application menu or add it as a non-Steam game. The first launch sets up a folder structure in your home directory where you place ROMs and BIOS files. No separate emulator configuration is needed; everything works out of the box.
Because RetroDECK is a Flatpak, updates come through Discover and are entirely self-contained. This sandboxing can cause minor issues with file paths or external tools, but for the average user, it means a hassle-free experience that rarely breaks.
User Interface and Ease of Use
Both projects use EmulationStation Desktop Edition as their primary game browser, so the look and feel are nearly identical. You scroll through system icons, pick a game, and hit play. Where they differ is in what happens behind the scenes.
EmuDeck offers more ways to launch games. With Steam ROM Manager configured, your entire collection appears directly in your Steam library with gorgeous artwork, just like official Steam titles. This deep integration is fantastic for those who want to stay inside Gaming Mode and never touch Desktop Mode. However, it can be overwhelming to manage if your library is huge, and any hiccup in the scraping process can lead to missing art or broken shortcuts.
RetroDECK keeps things simpler: you launch the app and then pick your game. This feels more like booting a standalone console. It does not clutter your Steam library with hundreds of entries, but it also means you are always one extra step away from your games. For beginners, this simplicity is often a relief. There is less to go wrong, and the focus is squarely on playing rather than curating a library.
Performance and Compatibility
In terms of raw performance, the differences are negligible. Both run the same emulator cores (RetroArch and various standalones) and both can handle everything up to PlayStation 2 and GameCube with ease on the Steam Deck. EmuDeck may give you a slight edge in edge cases because it uses the latest versions of standalone emulators, which sometimes offer better performance or compatibility than the Libretro cores bundled in RetroDECK. For example, the standalone version of PCSX2 in EmuDeck can be slightly faster than the RetroArch core in RetroDECK, but the difference is small and rarely noticed by casual players.
Battery life is similar between the two, as the underlying emulators are identical. One area where RetroDECK shines is consistency. Since everything is tested together as a single package, you are less likely to encounter conflicts or broken configurations after an update. EmuDeck’s mix of package sources sometimes leads to a broken emulator until you manually fix it, which can be frustrating if you just want to play a game.
Customization and Features
EmuDeck is the clear winner for tinkerers. You can dive into each emulator’s settings, replace emulators entirely (say, using Yuzu instead of Ryujinx), change shaders, and fine-tune performance. The Steam ROM Manager lets you customize artwork, choose which games appear in Steam, and even apply per-game controller profiles. This level of control is perfect for advanced users who want to build a highly personalized emulation machine.
RetroDECK deliberately hides most of these options. You can still adjust some settings through its built-in configuration menus, but you cannot swap out emulator cores or make deep system changes. The project’s philosophy is that less choice means fewer opportunities for mistakes. For many users, this is a feature, not a drawback. It keeps the experience clean, predictable, and console-like.
Which One Should Beginners Choose?
If you are new to emulation on the Steam Deck, RetroDECK is the safest starting point. It installs in seconds, requires zero configuration, and gives you a straightforward way to play your ROMs without ever opening Desktop Mode except to copy files. The risk of breaking something is extremely low. If you outgrow it later, you can always uninstall it and switch to EmuDeck without losing your ROMs or saves.
On the other hand, if you are comfortable with basic computer tasks and want the best possible integration with Steam’s interface, EmuDeck is worth the extra effort. You will get a more seamless Gaming Mode experience and the flexibility to tweak things down the road. Just be prepared to spend some time setting it up and maintaining it.
EmuDeck vs RetroDECK vs Batocera: A Brief Comparison
Batocera takes a completely different path. Instead of running inside SteamOS, it is a full Linux operating system designed solely for emulation. You install it on a separate SD card or USB drive and boot into it when you want to play retro games. This approach offers the most console-like experience possible, with an attractive frontend and pre-configured emulators, but it means you cannot easily switch back to Steam without rebooting the whole device. For someone who only wants a dedicated emulation device, Batocera is excellent, but it is less convenient for those who want to blend emulation with modern PC gaming on the same handheld.
Between EmuDeck and RetroDECK, the choice comes down to flexibility versus simplicity. EmuDeck gives you a Swiss Army knife; RetroDECK gives you a dedicated appliance. Both will play your games beautifully, so pick the one that matches your comfort level.
Frequently Asked Questions
- Can I switch between EmuDeck and RetroDECK without losing my saves? Yes. Both store saves in standard locations. You can back up your save folders before uninstalling one and then point the other to the same location, but manual steps are required. It is not automatic.
- Does RetroDECK include all the same emulators as EmuDeck? Not exactly. RetroDECK bundles a curated set of cores, mainly from RetroArch, plus a few standalones. EmuDeck can install a wider range of standalone emulators (like Cemu for Wii U or Xenia for Xbox 360) that RetroDECK does not offer.
- Will using either of these get me banned from Steam? No. They do not modify SteamOS in any way that violates Valve’s terms, and emulation itself is legal. Only the use of unauthorized game copies can lead to issues, which is a separate matter.
- Is Batocera better than EmuDeck or RetroDECK for performance? Performance is essentially the same because all three leverage similar emulators. Batocera may feel snappier because it is a lightweight OS with no desktop overhead, but in-game frame rates will be identical.
- Do I need BIOS files for these emulation suites? Yes, certain systems (like PlayStation 1 and 2, Sega Saturn, and others) require a BIOS file to function. Both EmuDeck and RetroDECK provide folders where you must place these files manually. They are not included for legal reasons.
Ultimately, there is no universally right answer. RetroDECK excels at hassle-free simplicity, EmuDeck delivers unmatched flexibility and Steam integration, and Batocera offers a dedicated console experience. Whatever you choose, the Steam Deck is an emulation beast, and you are in for a treat.
