Most RPG Maker EULAs explicitly prohibit reverse engineering. For example, the RPG Maker 2003 EULA states:
The tool you need depends on the version of RPG Maker used to create the game. Here is a breakdown of the most prominent and effective tools available.
Using an engine-specific tool (such as Petschko's tool for MV/MZ or an RGSSAD decrypter for VX Ace), target your deployed game folder. Run the tool to output the decrypted graphics, audio, and database files into a fresh folder. Step 3: Reconstruct the Project Directory
The actual .exe or app runner is just a pre-compiled interpreter (like Ruby for older versions or Chromium/NW.js for newer versions) that reads these data files. Encryption Packages rpg maker decompiler
This is perhaps the most critical section. Using decryption tools comes with significant legal responsibilities.

RPG Maker engines (ranging from older versions like XP and VX Ace to modern versions like MV and MZ) use different methods to secure game data. Most RPG Maker EULAs explicitly prohibit reverse engineering
No protection is absolute, but you can raise the bar. A determined cracker will always succeed, but 99% of casual thieves will move on if you make it annoying.
These older engines use a different architecture, storing data in the Lmu (Map) and Ldb (Database) formats.

Just a friendly reminder to use these tools ethically! They are great for learning and recovering your own lost work, but always respect other creators' assets and licenses.
Similar restrictions exist in the EULAs for other RPG Maker versions. While the legal enforceability of these clauses varies by jurisdiction, violating them can expose users to legal action, especially if decrypted content is redistributed.
