Retro tips and tricks: controllers, shaders, backups and less lag

The emulator is running? Then the details that make the difference begin. These are the tips that work in almost every retro system.

1. Keep your collection tidy

  • One folder per console, with the same naming convention everywhere.
  • Use descriptive file names. Programs that fetch cover art (scrapers) recognize games by them.
  • Convert disc images to .chd with chdman (included with MAME): chdman createcd -i spel.cue -o spel.chd. That saves a lot of space.

2. Getting games legally

  • Your own collection: dump your own discs and cartridges.
  • Homebrew and freeware: in RetroArch via Online Updater → Content Downloader, and on sites like itch.io.
  • Re-released: GOG, Steam and the eShop and PlayStation collections.

Avoid “ROM-packs” and random download sites: that’s usually illegal and a risk to your PC.

3. Controllers

  • An Xbox or DualSense controller works almost everywhere directly. For retro, 8BitDo controllers are popular.
  • Connect a controller first with a cable for setup and only test wirelessly after that.
  • Set up your buttons once and save the profile.

4. Less lag (input lag)

  • Use a wired controller or a good wireless one with dongle.
  • In RetroArch: Settings → Latency → Run-Ahead removes the built-in lag of many 2D games.
  • Set a fixed refresh rate and use a monitor or TV with game mode.

5. Image quality

  • Integer scaling for pixel-sharp image in a fixed ratio.
  • CRT shaders (like crt-geom) for the look of an old CRT. Heavier variants require a powerful video card.
  • For 3D consoles: a higher internal resolution and widescreen patches.

6. Saves and backups

  • Save states are handy, but also save your game normally within the game itself. States may no longer work after an update.
  • Back up your save and state folders and sync them with a NAS or a program like Syncthing.

7. Extras

  • RetroAchievements (free account) adds achievements to old games.
  • Rewind and fast-forward mode are great for practice.
  • Home network: put your collection on a NAS and share it with all your devices.
