You can check the region of your GameCube by looking at the sticker on the bottom of the console.

While a 2GB Micro SD card is required to boot Swiss on startup, the GameCube can read larger MSD cards, such as a 64GB card when you are in the Swiss menu.

Ensure that your SD card is formatted to FAT32. Watch this to find out how: https://youtu.be/ijWIs5xYYoM

You must use an SD card and it must go into the SD card slot.

You can’t use a USB adapter or any kind of USB device instead of an SD card.
