About this mod Machine translation

BepInEx is the necessary pre-framework for "Return Store Simulator" to run all mods. Various functional modules can be loaded after installation.

Module introduction

BepInEx is a common module loading framework for Unity games, providing a basic environment for Mod running in "Return Store Simulator". As a pre-dependency of all functional modules, you can use various practical modules such as customer acceleration, time adjustment, and random placement of items after installing BepInEx.

Features

  • Full mod loading support for Return Store Simulator
  • Supports IL2CPP version of Unity engine, with excellent compatibility
  • Built-in Harmony patch system to achieve safe function injection
  • Provide configuration file management to facilitate debugging and customization
  • Lightweight framework with minimal impact on game performance

Installation method

  • Download BepInEx compressed package
  • Extract all files in the compressed package to the game root directory of "Return Store Simulator"
  • Make sure the `BepInEx` folder is located directly in the game root directory (at the same level as the game executable)
  • Start the game once and BepInEx will automatically generate the configuration file
  • Then put the DLL plug-ins of other Mods into the `BepInEx/plugins` folder.
  • Press F5 to open the BepInEx console in the game

Notes

  • This module is a framework and will not change the game content after installation.
  • You need to download additional specific functional modules (such as customer acceleration, time adjustment, etc.) to experience the modification effect
  • If the framework fails after the game is updated, please go to the page to check if there is a new version.
  • When uninstalling the Mod, you can directly delete the BepInEx folder without affecting the original game files.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
