🎮 Steam Deck Guide

OpenROM runs great on Steam Deck using the Linux build.

Setup

  1. Switch to Desktop Mode (Power → Switch to Desktop)
  2. Download OpenROM_Linux_x86_64.zip from GitHub Releases
  3. Extract it to your home folder or SD card
  4. Open Konsole (terminal) and make it executable:
cd ~/OpenROM_Linux_x86_64/
chmod +x OpenROM openrom-core
./OpenROM

Add to Game Mode (Optional)

To launch OpenROM from Game Mode:

  1. In Desktop Mode, open Steam
  2. Click Add a Game → Add a Non-Steam Game
  3. Browse to the OpenROM binary and add it
  4. In the game properties, set a controller layout

SD Card

If your ROMs are on the SD card, they're at:

/run/media/mmcblk0p1/

Example batch conversion:

./openrom-core --folder /run/media/mmcblk0p1/roms/ps1/ --format CHD

Tips

  • Use the CLI for bulk conversions — faster than the GUI for large collections
  • Convert before adding to EmulationStation — CHD loads faster than ISO on the Deck
  • CHD for everything disc-based — saves SD card space significantly
  • RVZ for GameCube/Wii — Dolphin on Deck supports RVZ natively

Recommended Workflow

1. Copy ROMs to SD card via PC
2. Open OpenROM on Deck (Desktop Mode)
3. Batch convert PS1/PS2 → CHD
4. Batch convert GC/Wii → RVZ
5. Add converted files to EmulationStation
6. Delete original ISOs to save space

→ Installation → Conversion Matrix → Troubleshooting
