SmartSteamEmu is a Steam client emulator that allows for the simulation of Steam's functionalities for games that utilize its API. With it, it is possible to run Steam-only games without the need for the official client, providing support for LAN or online multiplayer modes when applicable.
It also allows for the customization of settings and the creation of specific files for emulation.
The main objective of SmartSteamEmu is to offer a functional alternative to the Steam client for testing and modification purposes, but its use must respect the copyrights and usage policies of the games and the platform.
