This functions essentially the same as the language selector. The language selector now also checks the currently set option on launch, and both the language and theme selectors spawn a popup prompting the user to restart NUSGet after selecting a new value.

 The following features are available for all supported consoles:
 - Downloading encrypted contents (files like `00000000`, `00000001`, etc.) directly from the update servers for any title.
-- Creating decrypted contents (*.app files) from the encrypted contents on the servers. Only supported for free titles.
+- Creating decrypted contents (*.app files) from the encrypted contents on the servers.
 - Scripting support, allowing you to perform batch downloads of any titles for the Wii, vWii, or DSi in one script. (See `example-script.json` for an example of the scripting format.)
 
 **For Wii and vWii titles only:**
-- "Pack installable archive (WAD/TAD)": Pack the encrypted contents, TMD, and Ticket into a WAD file that can be installed on a Wii or in Dolphin Emulator. Only supported for free titles.
+- "Pack installable archive (WAD/TAD)": Pack the encrypted contents, TMD, and Ticket into a WAD file that can be installed on a Wii or in Dolphin Emulator.
+- Forging Tickets for titles without a common Ticket available on the NUS by using the Title Key algorithm to derive the key needed to decrypt the title.
 
 **For vWii titles only:**
 - "Re-encrypt title using the Wii Common Key": Re-encrypt the Title Key in a vWii title's Ticket before packing the WAD, so that the WAD can be installed via a normal WAD manager on the vWii, and can be extracted with legacy tools. **This also creates WADs that can be installed directly in Dolphin, allowing for running the vWii System Menu in Dolphin without a vWii NAND dump!**
