The Sims (GameCube) Requires a 59-Block Memory Card, Not 60

The Sims on GameCube only saves to an official 59-block (512 KB) Memory Card. Third-party "60-block" cards (often marketed as 251/1019 blocks = 2MB/8MB) will not be recognized by the game.

Why This Happens

• The game's save routine checks for the exact official Nintendo 59-block format (specific File ID and checksum structure).
• Third-party high-capacity cards use different banking and addressing schemes. The game reads them as "Corrupted" or "No Card."

Solutions

1. Buy an official Nintendo 59-block card (DOL-008): Grey with the "Nintendo GameCube" logo. Typically $10–$20 used. Most reliable option.
2. Use a 251-block official card (DOL-014): Black, labeled "251 Blocks." Works because it's essentially four 59-block banks; the game uses the first bank.
3. Softmod + SD Gecko / GCLoader: Redirect saves to an SD card via homebrew. Requires a modded GameCube or Wii.

Don't Waste Money On

• Generic "60/128/256/1019 block" cards (Mad Catz, Nyko, Performance, unbranded). They work for other games, but not The Sims.
• Formatting in the Wii Menu—it doesn't change the card's hardware ID.

Get the grey 59-block card. It's the only guarantee.
