HokakuCafe

Applies IOSU patches to write network frames to a .pcap file. Also dumps NEX account tokens, which are needed for packet decryption.
All files will be in the HokakuCafe folder on the root of your SD Card.

The filename for the token will contain the Principal and Game ID: nexServiceToken-<pid>-<gameid>.bin.

Usage

Homebrew Launcher

1. Copy the HokakuCafe.rpx to the wiiu/apps folder.
2. Open the HBL and launch HokakuCafe.
3. Launch a game and the packets will be written to the SD.

Setup Module

The setup module works with both Tiramisu and Aroma ([ENVIRONMENT] is a placeholder for the actual environment name).

1. Copy the 30_hokaku_cafe.rpx to the wiiu/environments/[ENVIRONMENT]/modules/setup folder.
2. Launch a game and the packets will be written to the SD

Make sure to only remove the SD Card after powering off the system, to make sure all data has been written.
