How to use the GBA link cable online
In Gaemboy you don't need a physical cable: two players connect their browsers directly and the emulators exchange link-cable data in real time, so you can trade and battle in supported Game Boy Advance games.
Open Gaemboy →Requirements
- Two devices, each running Gaemboy in a browser.
- The same supported Game Boy Advance game on both.
- A stable connection — same Wi-Fi is the most reliable.
Step by step
- Player 1 opens a supported Game Boy Advance game in the emulator.
- Player 1 starts a link session from the emulator menu.
- Player 2 joins the same session from their own device.
- Both players open the in-game trade or link menu and connect as they would with a real cable.
Common problems
- Won't connect: keep both tabs in the foreground and retry from the in-game link menu.
- Unstable over mobile data: same-Wi-Fi sessions are the most reliable.
- Game not trading: make sure both players use the same, supported title.
FAQ
Do I need a cable or adapter?
No. Everything runs in the browser — no cables, adapters or apps.
Can we play on different networks?
Yes, it can work across networks depending on connection quality, but the same Wi-Fi is the most reliable.
