Author: Generative AI Date: October 2023 Subject: Game Modification & Web Technologies Abstract RPG Maker (specifically versions XP, VX, VX Ace, MV, and MZ) utilizes proprietary, serialized file formats (e.g., SaveXX.rvdata2 , fileXX.rmmzsave ) to store game progress. While manual save editing using desktop tools like RPG Maker Save Edit or Cheat Engine is established, the emergence of web-based save editors presents unique challenges in file parsing, client-side security, and cross-version compatibility. This paper examines the architecture of a theoretical "RPG Maker Save Editor Online," focusing on the Ruby Marshal (pre-MV) versus JSON (MV/MZ) serialization dichotomy, the security implications of browser-based decryption, and the ethical boundaries of save manipulation. 1. Introduction RPG Maker is one of the most accessible game development engines, powering thousands of indie RPGs. Due to the predictable structure of its save files, players often edit these files to modify variables, gold, items, or party attributes. Traditional save editors are platform-dependent (Windows executables). An online editor promises universal accessibility but introduces technical hurdles: handling binary data in JavaScript, managing encryption (RPG Maker MV/MZ uses AES-256-CBC for some deployments), and ensuring user data privacy. rpg maker save editor online
