This repository contains the HF Patch installer for AI-Syoujyo/AI-Shoujo, a comprehensive mod and update pack for the Illusion game. It uses Inno Setup to create a modular installer that updates the game, installs plugins, translations, mods, and uncensors. The patch supports both Steam and Japanese versions, performs game file validation, and offers component selection. The repository itself does not contain the actual mod files (they are too large), but rather the installer configuration and a helper library submodule. It is not a typical software application but an installer definition, with the core logic in Inno Setup scripts.
