Author: AI Research & Development Date: October 26, 2023 Version: 1.0 Abstract RPG Maker MV (RMMV) is a popular game engine that utilizes HTML5, CSS, and JavaScript, allowing developers to deploy games to multiple platforms. While the engine includes a native debug window (F8), its functionality is limited to console logging and basic variable inspection. This paper details the development of a custom graphical cheat menu overlay. The objectives include modifying runtime game parameters (gold, stats, items, invincibility), understanding the engine’s event architecture, and analyzing the security implications of client-side JavaScript manipulation. The results demonstrate that due to the engine’s unencrypted exposed core scripts, implementing a persistent cheat menu is trivial for anyone with moderate JavaScript proficiency. 1. Introduction RPG Maker MV differs from its predecessors (XP, VX Ace) by relying on JavaScript (Node.js-like environment) rather than Ruby. The core game logic resides in js/rpg_core.js , js/rpg_objects.js , and js/rpg_windows.js . Because these scripts are executed on the client side, end-users have full access to the game’s memory and functions via browser developer tools.
