The gaming Linux distros making noise this year (CachyOS, Bazzite, plus the Steam Deck’s own SteamOS) have quietly settled the “what OS should I emulate on” question. What is not settled is the frontend. RetroArch is fine but not everyone’s aesthetic, LaunchBox looks incredible but costs money, and ES-DE has taken over the handheld scene. We ran seven of them on the same shared ROM library, on Windows, a fresh CachyOS install, and a Steam Deck, to see which frontend deserves to be the one you point at your archive.
This is for people whose emulator collection has spread across too many launchers and who want one place to browse the whole thing. If you are looking for a standalone GameCube or PS3 emulator, this is not the roundup for you.
What to look for in an emulator frontend
- How many emulator cores or standalone binaries it wraps out of the box
- Metadata scraping (box art, marquees, descriptions) and how much manual cleanup you end up doing
- Controller-first navigation, since most people use these on a couch or a Steam Deck
- Shader support for CRT effects, scanlines, and integer scaling
- Save state and per-system settings management
- Whether it plays nicely with Steam Big Picture / Gamescope

The frontends
1. RetroArch, the frontend that wraps everything
RetroArch is not just a frontend; it is a runtime that runs Libretro cores for hundreds of systems, from Atari 2600 to PSP to arcade sets. One binary, one UI, one library. It is the deepest system on this list because every core lives inside RetroArch’s own UI. On desktop it feels like an Xbox dashboard: playlists on the left, cover art in the middle, a text info column on the right.
Where it falls short: the interface has a learning curve. Configuring input, overlays, and per-core settings takes a Sunday afternoon the first time. Some people find the UI ugly.
Pricing: Free, GPLv3.
Platforms: Windows, macOS, Linux, Steam Deck, Xbox (dev mode), and more.
Download: retroarch.com
Bottom line: The pick if you want maximum system coverage in one binary and are willing to configure.
2. LaunchBox, the best-looking library
LaunchBox and its Big Box couch mode are what people show off in videos. The library grid looks like a store frontend, the box art is enormous, and the scraper pulls high-quality metadata from EmuMovies and GamesDB. LaunchBox itself is free; Big Box (the TV-friendly mode) requires the paid Premium license.
Where it falls short: Windows only. The Premium license is a real cost, and pricing has shifted over the past year. Emulator setup is manual; LaunchBox does not ship with cores like RetroArch does.
Pricing:
- Free: LaunchBox desktop mode
- Paid: Premium adds Big Box couch mode, around $50/year or $110 lifetime
Platforms: Windows only. Android app for mobile.
Download: launchbox-app.com
Bottom line: The prettiest frontend, Windows only, worth the money if you play on a TV.
3. ES-DE, the handheld standard
ES-DE (EmulationStation Desktop Edition) has become the default frontend on Steam Deck and Linux handhelds. It uses ES-native themes, ships with sensible defaults for most emulators, and its scraper against ScreenScraper is fast and accurate. Big controller-friendly UI, portrait mode support for vertical handhelds.
Where it falls short: not as configurable as RetroArch. Metadata editing is per-game and manual; there is no bulk edit view.
Pricing: Free; the developer accepts donations and offers a paid app version around $2 on some stores.
Platforms: Windows, macOS, Linux, Steam Deck, Android.
Download: es-de.org
Bottom line: The default answer for Steam Deck and Linux handheld emulation.
4. Playnite, when emulation lives next to Steam
Playnite is a game library manager that treats Steam, GOG, Epic, and emulator ROMs as equal entries. Perfect when your library mixes modern PC games with retro emulation and you want one launcher for everything. Add-ons cover ROM importers, HowLongToBeat integration, and library backups.
Where it falls short: Windows only. Setting up emulators inside Playnite is more work than doing it in a dedicated frontend, because Playnite is really a launcher first.
Pricing: Free, MIT.
Platforms: Windows.
Download: playnite.link
Bottom line: Best when you want one library for Steam, GOG, and your ROMs.
5. Batocera, the whole-OS approach
Batocera is not a frontend on top of your OS; it is an entire OS built around emulation. Flash it to a USB stick, boot into it on any x86 PC or a Raspberry Pi, and you get a frontend + all cores + save management out of the box. Great for repurposing an old PC as a dedicated emulation box.
Where it falls short: it is an OS, not an app. If you want to run other things on the same machine, you have to dual-boot or use a live USB.
Pricing: Free, GPLv3.
Platforms: x86 PC, Raspberry Pi, Odroid, various handhelds.
Download: batocera.org
Bottom line: The right answer for a dedicated retro box, not an everyday desktop.
6. EmuDeck, the Steam Deck setup wizard
EmuDeck is technically a setup script, not a frontend itself. It installs and configures ES-DE (or RetroArch), sets up all the emulator binaries, and configures shortcuts to launch everything from Steam. The end result is that a fresh Steam Deck goes from stock to fully set up in about 15 minutes.
Where it falls short: it wraps other frontends rather than replacing them, so you still learn ES-DE or RetroArch afterwards. If your emulation setup is unusual, EmuDeck’s defaults can fight you.
Pricing: Free, GPLv3.
Platforms: Steam Deck (main), Linux, Windows, macOS.
Download: emudeck.com
Bottom line: The Steam Deck setup script that saves you a weekend of configuration.
7. Pegasus Frontend, custom themes for tinkerers
Pegasus Frontend is the choice for anyone who wants to build their own theme. Themes are written in QML, which means anyone who has done a bit of Qt work can produce a completely custom UI. The default theme is fine; the community themes range from Nintendo Switch-lookalikes to Windows 95 revivals.
Where it falls short: metadata scraping is less automated than ES-DE or LaunchBox. Configuration is text-file driven.
Pricing: Free, GPLv3.
Platforms: Windows, macOS, Linux, Android.
Download: pegasus-frontend.org
Bottom line: The pick when you want to design your own emulator frontend and are comfortable in a text editor.
How to pick the right one
If you want everything in one binary and do not mind configuration: RetroArch.
If you want the prettiest possible library and are on Windows: LaunchBox + Big Box.
If you emulate on a Steam Deck or a Linux handheld: ES-DE, likely via EmuDeck for the initial setup.
If you want one launcher for Steam, GOG, Epic, and your ROMs: Playnite.
If you want a dedicated retro-box OS on an old PC: Batocera.
If you want to build your own custom theme: Pegasus Frontend.
FAQ
Is RetroArch the same as EmulationStation?
No. RetroArch is a runtime that runs Libretro cores and includes its own frontend. EmulationStation (and its ES-DE fork) is only a frontend; it launches external emulators.
Which emulator frontend is best for Steam Deck?
ES-DE is the standard, and EmuDeck is the setup wizard that configures ES-DE plus every emulator on a fresh Steam Deck.
Can I use one ROM folder across multiple frontends?
Yes. RetroArch, ES-DE, LaunchBox, and Playnite can all point at the same folder tree. Reading progress and save states will not sync between them, but the ROMs themselves are untouched.
Do I need a subscription for LaunchBox?
The desktop mode is free forever. Big Box (the couch mode) requires a Premium license, sold as an annual subscription or a lifetime buy-once.
Which frontend has the best metadata scraping?
ES-DE and LaunchBox are the strongest. RetroArch’s built-in scraper works but requires more manual cleanup, particularly for arcade sets.
