NSScreenshotMaker is a tool that will allow you to sign images for the Nintendo Switch. The Switch has an album function to view your screenshots, but it can't read images you put yourself on the SD card.

This tool's purpose is to sign any image so the Switch can read it.

User guide

Requirements:

• The Nintendo Switch capsrv screenshot HMAC secret key.
• Python3.
• PIL.
• piexif.

You might otherwise use the exe file which doesn't need those requirements (except for the key). Your antivirus may block it however.

How to use:

• Find the "Nintendo Switch capsrv screenshot HMAC secret" key (not provided for legal reasons). Either save it in a key.bin file, or pass it as an argument when running the program.
• Create an input folder, and put your images in it. Images can be all sizes and formats that PIL supports.
• Download the program and run it. It should output an SD folder. Extract its content to the root of your Switch's SD card.

Changelog
