Usage

Host computer

Clone the repo and open the project in Visual Studio or Rider, then just launch the project.

Client

Make sure you are running the Nesys service (this can be copied from a stock machine drive from D, make sure to put it in the same folder on D as on the original drive). A service entry can be made using Utils/create.bat. Install the registry keys located in the same folder. Modify your hosts file (C:\Windows\System32\drivers\etc\hosts) or use a proxy to point the following domains to your host computer. Example: (this is assuming your server and client are the same computer)

127.0.0.1 cert.nesys.jp

127.0.0.1 cert3.nesys.jp

127.0.0.1 data.nesys.jp

127.0.0.1 proxy.nesys.jp

127.0.0.1 nesys.taito.co.jp

127.0.0.1 fjm170920zero.nesica.net

Install the certificates located in LLServer/Certificates on the client computer using the powershell script located in the same folder. You will then need to patch the game to replace the RSA key to the one used in the server. The public key is located at file offset 0x595200. The public key that should be used:

-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----

This key can also be found in LLServer/Common/CryptoConstants.cs. If everything is set up correctly, you should be able to start the game and use the original IO board / card reader to scan your card and connect to the server.
