This tool allows an user to download content from the Nintendo 3DS CDN without a 3DS, after extra server-side checks were added for 11.8+.
This will require the user to have signed tickets for the target content.

A little warning, like the 3DS, it will send the signed ticket encrypted in a wrapper, otherwise it's impossible to access content.
Be aware the servers will have your ticket everytime you send it and unique eshop tickets come with console and account ids.

This tool is not required for system titles. Any other tool can access those titles without a ticket, they can't add checks to these titles since it would break system updates for older versions.

Just for the record, I didn't create this tool to condone piracy, but it is inevitable and I know someone will use it for such purposes.
Regardless, the way you use this tool is entirely your responsibility.
Please respect and support the developers of games, DLC, themes, and other content you use by purchasing it.

The tool itself is under MIT. Read LICENSE.
