rpgm-decrypt

rpgm-decrypt is a small open-source command-line tool that decrypts and extracts

  RPG Maker asset files across every engine:

    • XP / VX / VX Ace — .rgssad / .rgss2a / .rgss3a archives

    • MV / MZ          — encrypted .rpgmvp / .png_ / .ogg_ / .m4a_ files and .pak archives

  It finds the encryption key automatically, restores the original files, and leaves

  non-asset/system files untouched.

  Good for: translating your own games, backing up and recovering your own project

  assets, and studying the formats.

  Usage (one command):

      rpgm-decrypt "path/to/game" "output/folder"

  On Windows you can also drag a game folder onto decrypt.bat.

  Single self-contained binary — no install, no dependencies. License: Apache-2.0.
