EOSSDK-Holos

EOSSDK-Holos is an emulation layer for the Epic Online Services (EOS) SDK. Its primary objective is to make possible true Peer-to-Peer multiplayer connectivity by intercepting and redirecting P2P traffic over a direct UDP socket.

This patch is particulary made for Holos Hanafuda, tested on version 1.2.0 under wine

Build

  1. Place the contents of this repository into the game's plugin directory:

Holo's Hanafuda\HolosHanafuda_Data\Plugins\x86_64\

The project acts as a DLL proxy. To ensure the game can still access the original SDK functions, you must rename the existing file:

  1. Locate EOSSDK-Win64-Shipping.dll in the directory mentioned above and rename it to EOSSDK-Win64-Shipping_orig.dll.

Execute the build script provided in the repository to generate the proxy DLL:

bash ./build.sh
