rpgmdec

README на русском

RPGMDec is a universal, lightweight (1 MB executable) GUI for decrypting and encrypting RPG Maker archives and assets.

File names inside archives are read as UTF-8; use the Encoding menu (e.g. Shift-JIS) for archives of older Japanese games.

rpgmdec is built on these Rust libraries:

• rpgm-asset-decrypter-lib
• rpgm-archive-decrypter-lib

Installation

Get the binaries from Releases. They require x86-64-v2 and AES-NI support.

Usage

See Help.

Supported Formats

Besides decrypting and encrypting, the program can play audio and preview images and ttf/otf fonts.

Decrypt

• Archives: .rgssad, .rgss2a, .rgss3a
  • Data: rxdata, rvdata, rvdata2
  • Images: png
  • Audio: ogg, m4a
  • Fonts: ttf, otf
• Assets: .rpgmvp/.png_, .rpgmvo/ogg_, .rpgmvm/m4a_

Encrypt

• Data: rxdata, rvdata, rvdata2
• Images: png
• Audio: ogg, m4a
• Fonts: ttf, otf

Building

You need Rust 1.88, CMake and a C++ compiler, since FLTK is built from source by default (see system-fltk below). On Linux, the packages to install are listed in .github/workflows/release.yml.

git clone https://github.com/RPG-Maker-Translation-Tools/rpgmdec
cd rpgmdec
cargo build --release

The binary is target/release/rpgmdec (rpgmdec.exe on Windows).

Features

Feature	Default	Effect
gxhash	yes	Uses gxhash for the app's hash maps. Needs AES-NI (or Armv8 crypto).
rapidhash	no	Uses rapidhash instead. Only applies when gxhash is off.
mimalloc	yes	Uses the mimalloc allocator.
system-fltk	no	Links an installed FLTK 1.4+ found by CMake, instead of building the bundled copy.
system-png	no	Uses the system libpng instead of FLTK's bundled one.
system-jpeg	no	Uses the system libjpeg instead of FLTK's bundled one.
system-zlib	no	Uses the system zlib instead of FLTK's bundled one.
static-msvcrt	no	Links the MSVC C runtime statically. Used by the Windows release build.
use-ninja	no	Builds FLTK with the Ninja generator when ninja is on PATH. MSVC builds pick Ninja the same way.

Turn off the defaults to build with rapidhash instead of gxhash, and add mimalloc back if you want it:

cargo build --release --no-default-features --features rapidhash,mimalloc

--features adds to the defaults, e.g. cargo build --release --features system-zlib.

Support

Me, the maintainer of this project, is a poor college student from Eastern Europe.

If you could, please consider supporting us through:

• Boosty (has lower fees)
• Ko-fi

Even if you don't, we will still continue working on the project anyways.
