  1. Choose what to play

    Both of you pick the same option. Kizuna is only switching on what we've tested.

  2. Connect your GB-Link

    First time? Set up your GB-Link at GB-Link first

    Kizuna Link uses the GB-Link's own firmware – you install and update it with GB-Link's tools, then come back here.

    1. Got a GB-Link adapter? Open the GB-Link Launcher, click Connect under Device Health and update to the latest firmware (2.2.7 or newer).
    2. Built your own on a Raspberry Pi Pico? Download the latest .uf2 from GB-Link's firmware releases, hold the BOOTSEL button while plugging the Pico in, then drag the .uf2 onto the RPI-RP2 drive that appears.
    3. Not showing up when you click Connect? Unplug it and plug it back in normally (without holding BOOTSEL), check the cable carries data (some are charge-only) and that no GB-Link tab is open.
    4. Close the GB-Link tab when you're done – only one tab can use the device at a time.
    • GB-Link updated to the latest firmware (see above if you're not sure).
    • No GB-Link Launcher or other GB-Link tabs open.
    • Link cable from the GB-Link into your Game Boy Advance.
