How to get the Data Disk in Crow Country

The Data Disk is a mandatory late-game item that also acts as a key to accessing the game’s several computer terminals. Getting it is a bit roundabout and requires solving a puzzle located in the Ocean Kingdom Arcade.

The first step in our journey is going to be restoring power to the Arcade itself. The Arcade can be found in the Northwestern section of the Ocean Kingdom area, which is itself West of the main plaza. To restore power to the Arcade, you’ll need access to the the circuit breaker, which requires the Silver Key to open.

To be more specific: circuit breaker is in the top left of the image above, and the coin machine with the puzzle hint and Data Disk are at the right.

Once you’ve got the power on, you can read a note near the machines that tells you which scores each machine will need to display to earn your prize. The order comes out to Mermaid, Dolphin, Boat, then Shark, with each score doubling the last. The games themselves are very simple, and you’ll need to earn the following scores to finish the puzzle:

• Mermaid: 1
• Dolphin: 2
• Boat: 4
• Shark: 8

Once you’ve achieved these scores, the Data Disk will dispense from the coin machine that had the puzzle clue. This disc can be used to access any of the game’s data terminals, including those in the Railway save room (to access the flamethrower) and the Dungeon (to find the glass bottle). There’s another terminal underground, but I’ll keep it vague in case of spoilers.
