RetroArch is a powerful all-in-one emulation frontend that lets you play games from dozens of classic systems. This guide walks you through setting it up specifically for SNES games on Windows.

What You Need

• A Windows PC (Windows 10 or 11 recommended)
• RetroArch downloaded from retroarch.com
• SNES ROM files (only use ROMs you own legally)

Step 1 — Download and Install RetroArch

Head to retroarch.com and download the latest Windows installer. Run the installer and follow the prompts. The default install directory is fine.

Once installed, launch RetroArch. You’ll see the main menu (XMB or Ozone depending on your version).

Step 2 — Download the Snes9x Core

RetroArch uses “cores” — each core is an emulator for a specific system. For SNES, the recommended starting core is Snes9x.

1. In the RetroArch menu, go to Main Menu → Load Core → Download a Core.
2. Scroll down to Nintendo - SNES / SFC and select Snes9x.
3. Wait for the download to finish.

If online core download is disabled, you can download cores manually from the Libretro buildbot and place them in the cores folder inside your RetroArch directory.

Step 3 — Configure Your Input

Before loading a game, set up your controller or keyboard.

1. Go to Settings → Input → Port 1 Controls.
2. Map each SNES button to your keyboard key or gamepad button.
3. A USB SNES-style controller or any generic gamepad works well.

Common keyboard default mappings: arrow keys for D-Pad, Z/X for B/A, A/S for Y/X, Enter for Start, Backspace for Select.

Step 4 — Load a Game

1. Go to Main Menu → Load Content.
2. Navigate to the folder where your SNES ROM files are stored.
3. Select a .sfc or .smc file.
4. RetroArch will ask which core to use — select Snes9x.

The game will launch. Press F1 at any time to bring up the RetroArch quick menu during gameplay.

Step 5 — Save States and Other Features

RetroArch’s quick menu (F1 during gameplay) gives you access to:

• Save State / Load State — instantly save and restore game progress at any point
• Core Options — adjust video, audio, and emulation settings for the Snes9x core
• Cheats — load cheat codes if needed
• Take Screenshot — captures to your Screenshots folder

Tips for Best Experience

• Enable integer scaling in Settings → Video for a crisp, pixel-perfect image.
• Try Shader Presets for optional CRT scanline effects under Quick Menu → Shaders.
• Set up a playlist by scanning your ROM folder under Import Content so your library appears in RetroArch’s menu.

That’s all it takes. Once configured, RetroArch is one of the most versatile emulation setups available, and the same frontend works for dozens of other classic systems too.
