Step 1. Connect the SD card to your EmuDeck Steam Deck, press the "STEAM" button, and choose "Settings."

Step 2. Navigate to the "System" section and locate the "Format SD Card" option on the right side.

It's crucial to check the EmuDeck settings to ensure correct paths and alignment with your gaming requirements.
