Formats from other tools that add headers, such as `.mcr` or `.ps2` with extra bytes, must be converted to raw images first. ## name.txt A one-line text file holding the name shown on the display and in the WebUI. It is created automatically from the built-in title database when a folder is first seen. Edit it, or use **Edit Name** in the WebUI, to change it. --- # 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/virtual-memory-cards/sd-card-layout.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.
