Tinfoil

A homebrew game, update, and DLC installer, and title key dumper.

Screenshots

Installation

• Create the directory /switch/dz/ on your switch's SD card.
• Copy dz.nro to /switch/dz/dz.nro.
• Obtain or generate a keys.txt file and place it in /switch/dz/keys.txt. keys.txt is a text file containing various Switch encryption keys. If you plan to generate it yourself, you can find instructions here: https://gbatemp.net/threads/how-to-get-switch-keys-for-hactool-xci-decrypting.506978/ or use kezplez-nx
• Copy locations.conf to /switch/dz/locations.conf. You should edit this file, it is only an example. It points to the various local and network locations hosting your Switch content. You can view an example of how to add the various supported protocols by looking at the locations.conf.examples.

Supported Protocols

Edit locations.conf to configure your install sources - you can mix and match. Only ip's can be used the the URL's, no hostnames. Note that all directory paths must end in a forward slash.

SD CARD

Supports installing from the local SD card. Use the URI sdmc:/ to point to the SD card. Subdirectories also work, for example sdmc://nsps/.

FTP

Regular FTP, not FTPS, not SFTP, normal plain jane FTP.

HTTP

HTTP requires directory listing / browsing be enabled.

USB

Requires a configured nut server. See here for details.

NUT SERVER

Requires a configured nut server. See here for details. Always ensure you are running the latest NUT server with Tinfoil.

Trouble shooting

Only SD is listed in your locations in the application

Either your locations.conf is not located at /switch/dz/locations.conf, it is invalid JSON, or you saved the file as unicode.

• Ensure /switch/dz/locations.conf exists on your SD card.
• Ensure your locations.conf passes validation at https://jsonlint.com/ .
• Ensure you did not save your locations.conf file as unicode, the hidden BOM bytes will break parsing.

I see my network locations, however no files are listed

Either Tinfoil cannot cannot connect with the network settings provided, you are using http and did not enable directory browsing, your firewall is blocking the connection.

• Ensure that you can connect to the FTP/HTTP/NUT server using the provided settings from a different PC than the one running the server.
• Tinfoil does not support sub directories, so each directory must point to the exact directory the NSP's are located in.
• Ensure your firewall is allowing external connections. Configure or disable your firewall.
• If using HTTP, ensure that directory listing / browsing is enabled. This must be manually enabled with IIS.

I can see the files, but cannot download them.

• Ensure the url in your locations.conf ends with a forward slash.
• If using HTTP, verify that you can download the file using a web browser. IIS requires you to add a MIME type for NSP (application/octet-stream) before you can download.

Tinfoil Hangs at a black screen when I launch it

Ensure the network settings (specifcally the IP) are correct.

Dumping Title Keys

Title keys are saved to sdmc:/switch/dz/titlekeys.txt when dumped. Additionally, you can place a single HTTP URL into /switch/dz/titlekeys.url.txt , to automatically submit your keys to that URL to back them up.

Disclaimer

Use at your own risk, and always have a NAND backup.

Additional Info

FAQ

What does each icon on the left mean?

On the left, you will see icons that indicate what is not yet installed on your Switch, but is on your PC (the game controller), and everything that is on your PC/server (PC icon). Anything that is listed under Games, DLC, and Updates, with the game controller icon next to it, is what is currently on your PC but not on your Switch. You can go to the Home tab to see everything that you have installed on your Switch.
