Hold **Right** and plug the device into the PC with a USB-C cable. Release when the display says **Release Button!**. 2. Select **Mass Storage**. The display shows **Mass Storage Mode**. 3. Eject the drive from the PC before unplugging. Unplug and reconnect to return to normal operation. Copying large game libraries is faster with a card reader. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://8bitmods.gitbook.io/manuals/boot-modes/mass-storage.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
