Best Emulators on the Steam Machine (Retro Gaming on SteamOS)
EmuDeck, RetroArch, and standalone cores turn the Steam Machine into a couch retro box that handles up through 6th/7th-gen and some 8th-gen emulation.
The Steam Machine is one of the best couch emulation boxes you can buy. It runs the same SteamOS as the Steam Deck, so the whole mature Linux emulation ecosystem just works, and you have far more thermal headroom and CPU than a handheld. Realistic ceiling: everything up through 6th/7th-gen (PS1, PS2, GameCube, Wii, Dreamcast, N64, PSP) runs cleanly, and a good chunk of 8th-gen (Switch, PS3, Wii U) is playable with per-game tuning. Below is the practical path: install once with EmuDeck, organize ROMs, and launch the whole thing from the couch in Big Picture.
Start with EmuDeck (the easy installer)
Do not hand-install a dozen emulators. EmuDeck is a script that downloads, configures, and controller-maps the major emulators for you, then wires them into a single launcher front-end. It was built for the Steam Deck and works the same on the Steam Machine.
- Boot into Desktop Mode (KDE Plasma). Power menu, then "Switch to Desktop."
- Download the EmuDeck installer from emudeck.com and run it. Choose Easy Mode the first time.
- Point it at a storage location for your ROMs and BIOS files. An external SSD or a roomy folder on internal storage both work.
- Let it install the emulator set: RetroArch, PCSX2, Dolphin, DuckStation, PPSSPP, melonDS, and friends.
- When it finishes, it offers to install Steam ROM Manager and an EmuDeck/ES-DE front-end.
EmuDeck keeps every emulator's controller layout consistent, so your gamepad behaves the same everywhere. This alone saves hours.
RetroArch vs standalone cores
You will use both, and EmuDeck sets up both.
- RetroArch is a single app that runs "cores" (each core is one emulator). It is ideal for the older, lighter systems: NES, SNES, Genesis, Game Boy / GBA, PC Engine, Master System, arcade. One consistent UI, shaders, save states, run-ahead for low latency. Use it as your catch-all for 2D-era consoles.
- Standalone emulators are dedicated apps that beat RetroArch cores on the heavier systems. Reach for the standalone every time for:
- PS2 → PCSX2
- GameCube / Wii → Dolphin
- PS1 → DuckStation (also a RetroArch core, but standalone is friendlier)
- PSP → PPSSPP
- Switch / Wii U / PS3 → their dedicated apps, with per-game settings
Rule of thumb: 8-bit and 16-bit eras live happily in RetroArch; anything 3D and demanding gets the standalone for better compatibility and tuning.
Add ROMs and the BIOS / legal note
Emulators are legal. The games are not yours to download. Dump your own discs and cartridges from hardware you own — that is the line SteamFPS holds, and it is also the only way to guarantee clean, complete files.
- Put ROMs in the folders EmuDeck created (it shows you the paths, organized per system).
- Some systems need a BIOS to boot: PS1, PS2, and Dreamcast in particular. EmuDeck has a BIOS-checker that tells you exactly which files are missing and where they go. Dump these from your own consoles.
- After adding ROMs, run Steam ROM Manager to generate launcher entries with box art.
We do not link ROM or BIOS sources. Own the hardware, dump the files, done.
Get it into Big Picture for couch play
This is the payoff: launch games from the sofa with a controller, no keyboard.
- In Desktop Mode, run Steam ROM Manager (EmuDeck installs it).
- Pick your parsers (the systems you added ROMs for), then Preview and Generate entries.
- Each game now appears as a non-Steam game in your Steam library, complete with artwork.
- Switch back to Gaming Mode / Big Picture. Your retro library sits right alongside your Steam games.
- Re-run Steam ROM Manager whenever you add new ROMs to refresh the entries.
If you prefer a console-style grid, EmuDeck can also launch ES-DE (EmulationStation Desktop Edition) as a single non-Steam entry — one tile that opens a full retro front-end.
What the hardware comfortably handles
The Steam Machine sits around RX 7600 / RTX 4060 class with a Zen 4 6-core CPU. Emulation leans hard on single-thread CPU and accuracy, and this box has plenty for the classic eras. These are community/estimated tiers, not lab benchmarks:
- Effortless (often upscaled past original res): NES, SNES, Genesis, N64, PS1, Dreamcast, PSP, Saturn, arcade. Expect full speed with internal-resolution bumps and shaders on.
- Comfortable with default-to-moderate settings: GameCube and Wii (Dolphin), PS2 (PCSX2) — most libraries run great at 2x–3x internal resolution. A few notoriously heavy PS2/Wii titles need tuning.
- Playable with per-game tuning (8th-gen): Switch and Wii U run a large share of their libraries, often very well, but expect occasional stutters and title-specific fixes. PS3 is the most demanding and most uneven — some games are great, others are a project.
The 8 GB VRAM ceiling is a non-issue for emulation; even aggressive upscaling stays well under it. Your limiter is CPU accuracy and per-game emulator maturity, not graphics memory. For modern native games the calculus is different — see which device and our methodology for how we test.
Frequently asked
You can install RetroArch alone, and for pure 2D retro it is enough. But EmuDeck installs and pre-configures the standalone emulators (Dolphin, PCSX2, PPSSPP) too, fixes controller mappings across all of them, and wires up Steam ROM Manager. For a few extra minutes it saves a lot of manual setup, so most people should start there.
Yes, with caveats. Switch emulation runs a large portion of the library well thanks to the capable CPU and GPU, though some games need per-title settings and patches. PS3 is the hardest target — emulation is uneven, so some games are flawless and others stutter or break. Treat 8th-gen as "playable and improving," not "flawless out of the box."
The emulator software is legal. Downloading games you do not own is not, and neither is sharing console BIOS files. The clean path is to dump ROMs and BIOS from hardware you actually own — that keeps you legal and gives you complete, uncorrupted files. SteamFPS does not link ROM or BIOS sources.
No. Steam ROM Manager adds your games as non-Steam shortcuts, which are non-destructive — you can remove them anytime by re-running the tool. Your installed Steam games are untouched, and the retro entries simply appear alongside them in Big Picture.
