To install the dissector, copy init.lua and the lua/ directory to %appdata%/Wireshark (or equivalent linux location at ~/.wireshark/).

This is done because the Wireshark plugin system sucks and has no way to guarantee load order. If you already have a custom init.lua you can probably figure out how to merge them.

You will need to add your NEX PID and your NEX password (for your device) in 'nex-keys.txt' in the Wireshark folder - the dissector will automatically derive the needed key from the PID/password and write it back to the file.

• Dissection of PRUDP v0 (3DS, WiiU friends)
• Automatic secure connection decryption if the connections are in the same pcap.
• Automatic generation of dissector code from wiki, including structure definitions.
• Data<> handling

• Dissection of PRUDP v1 (Some 3DS games, most Wii U uses) or PRUDP-Lite (Switch)
• Fragment reassembly.
• Work reliably.

Shoutouts to Kinnay's documentation at https://github.com/Kinnay/NintendoClients, it was absolutely essential to understand any of this.
