GBA Link Cable

GBA Link Cable lets 2, 3, or 4 players connect compatible Game Boy Advance games through Rebit. Use it for GBA games with built-in link features such as trading, battling, or local multiplayer menus.

Before You Start

  • Link Cable only appears for Game Boy Advance games.
  • Every player should use a Game Boy Advance game file they are allowed to use.
  • For best results, every player should start from the same game and ROM revision.
  • Save in-game before starting if you want current SRAM progress available in the linked session.
  • Use strong Wi-Fi when possible, and keep every game tab open.
  • Link Cable is in beta. Some games may not sync reliably.
  • Use Netplay for non-GBA multiplayer rooms.
  • Use Remote Controller if one phone should only act as a controller.
  1. Start a Game Boy Advance game.
  2. Tap the in-game menu button.
  3. Tap Link Cable.
  4. Choose 2P, 3P, or 4P.
  5. Tap Start Link Cable Room.
  6. Wait for Rebit to create the room.
  7. Copy the Room Code.
  8. Send the Room Code to the other players.

The host is Player 1. The Link Cable drawer shows the room status, room size, ping, and connected player role.

Join by Room Code

  1. Start the same Game Boy Advance game from your library.
  2. Tap the in-game menu button.
  3. Tap Link Cable.
  4. Type the Room Code from the host.
  5. Tap Join.
  6. Wait while Rebit prepares the linked session.

Joining players are assigned as Player 2, Player 3, or Player 4 depending on the room size and join order. After everyone is connected, use the game's own link cable menu to trade, battle, or start multiplayer.

Join from Discover

  1. Tap Discover in the bottom dock.
  2. Open the active rooms area.
  3. Find a room marked Link Cable.
  4. Tap Join.
  5. Choose a Game Boy Advance game from your library.
  6. Rebit opens the game and joins the Link Cable room.

If you do not have a Game Boy Advance game in your library, upload one first.

Link Cable uses the latest in-game SRAM save for each player. If Rebit cannot find an in-game save, the linked session starts with a blank save.

  1. Open Link Cable while the session is running.
  2. Tap Save.
  3. Wait for Rebit to store the Link Cable in-game save.

This saves the game's battery-backed in-game save, not a regular save state.

Pause, Resume, or Leave

  • The host can tap Pause or Resume in the Link Cable drawer.
  • Any player can tap Leave to disconnect from the room.
  • Tell the other players before leaving, especially before trading or saving inside the game.
  • In 3P or 4P rooms, ask every player to finish the game's own save routine before anyone leaves.
  • If Link Cable is disabled, confirm the game system is Game Boy Advance.
  • If joining fails, check the Room Code and ask the host to copy it again.
  • If a room appears in Discover as Link Cable, join it with a GBA game instead of the normal Netplay drawer.
  • If the game behaves differently for each player, restart with the same game and ROM revision on every device.
  • If a 3P or 4P session fails, run a short 2P test first, then add the remaining players after confirming the game can link reliably.
  • If Rebit reports a desync, restart the room before trading or saving.
  • If the mGBA Dual core fails to load, refresh both game tabs and try again.
  • Close unused browser tabs if the linked session feels slow.
