# Inside Game_System def save_contents data = Marshal.dump($game_system) checksum = Digest::MD5.hexdigest(data) data << checksum end An online editor must recompute such checksums; otherwise, the game will reject the modified save. 6.1 Single-Player vs. Multiplayer RPG Maker is predominantly single-player. Save editing is typically considered a form of accessibility or personal enjoyment, not cheating. However, if a game has online leaderboards (rare for RPG Maker), save editing becomes unethical. 6.2 Developer Rights Most RPG Maker EULAs allow end-users to modify savedata for personal use. Distributing a save editor does not infringe on copyright, as the editor does not contain game assets. However, bypassing strong encryption (e.g., DRM) may violate DMCA Section 1201 in the US. 6.3 Responsible Disclosure An online save editor should not claim to be "official" or imply developer endorsement. A disclaimer is recommended: "This tool modifies game files. Use at your own risk. Backup your saves." 7. Case Study: Editing "Game_Variables" Consider a user wants to change gold from 100 to 9999. In an MV save JSON:

// Decompress if needed (LZMA) if (saveObject.compressed) { saveObject.data = LZMA.decompress(saveObject.data); }

editVariable(saveObject, variableId, newValue) { // In MV/MZ, variables are stored as array inside data.variables saveObject.data.variables[variableId] = newValue; return saveObject; }

const decrypted = await crypto.subtle.decrypt( { name: 'AES-CBC', iv: iv }, keyBuffer, encryptedData ); return new TextDecoder().decode(decrypted); }

parseSaveFile(arrayBuffer) { const text = new TextDecoder().decode(arrayBuffer); const saveObject = JSON.parse(text);
