How GBA on Apple Watch works

The Watch app is a separate, small player. It does not mirror your iPhone screen: the game file is copied to the Watch and emulated there, so once a game is synced, the Watch can play it without your iPhone nearby.

GB, GBC and GBA games are supported. The app states it plainly: Apple Watch emulation is experimental. Audio is disabled, controls are basic, and performance depends on the game and the Watch model.

What you need

  • An iPhone with iGBA and at least one game already imported.
  • A paired Apple Watch with the iGBA Watch app installed.
  • Watch companion sync switched on in the iPhone app.

How to sync a game and play it on the Watch

  1. On the iPhone, open iGBA, tap Settings, then Apple Watch, and check that Watch companion sync is on. If you change it, restart the app.
  2. Open iGBA on the Watch. Your library from the iPhone appears in the list.
  3. Tap a game and tap Sync for Apple Watch. The game is copied to the Watch; keep both devices close until it finishes.
  4. When the screen shows ROM ready on this Watch, tap Play on Watch.
  5. To free space later, open the game again and tap Remove from Watch.

Use the Digital Crown as buttons

Every tap on a Watch screen covers part of the game. In the Watch app's settings, the Digital Crown option lets a turn of the Crown press a pair of buttons for you:

Digital Crown options on the Watch
OptionTurning the Crown
OffDoes nothing during a game
A / BPresses A one way and B the other
Up / DownMoves up or down, handy in menus and lists

The same settings screen has a button size option: small keeps more of the picture visible, large is easier to tap.

Honest limits

  • It is a beta: if a game does not start or feels slow, keep playing it on the iPhone.
  • There is no sound on the Watch: audio is disabled while a game runs there.
  • The screen is tiny, so games with a lot of text or small details are hard to read.
  • Emulation uses a lot of battery on a Watch; plan for short sessions.
  • The Watch app has its own library view; it is not a remote screen for the iPhone.

Questions and answers

Can you play GBA games on Apple Watch?
Yes, with iGBA's Watch app, as a beta. You sync a game from the iPhone, and it then runs on the Watch itself, with basic controls and no sound.
Does the Watch need the iPhone nearby to play?
Only to copy the game. Once it shows ROM ready on this Watch, the game runs locally on the Watch.
Which games run on the Watch?
Only GB, GBC and GBA games, and compatibility varies by game and Watch model. If one does not run well, play it on the iPhone.
