RF4S Modkit v0.1.0 — first release

A self-contained modding toolkit for Rune Factory 4 Special (PC / Steam). It reads and
writes the game's own files: maps, cutscenes, dialogue, textures, models and the game's data
tables. It comes with a GUI and a command-line tool.

No game data is included. You need your own copy of RF4S. The toolkit reads the game's
files from your install. Modding a copy of the game is recommended; the toolkit can make one
for you on first start.

Getting started

  1. Unzip rf4s-modkit.zip anywhere, for example into your game copy.
  2. Double-click start.bat. The first time it finds (or offers to install) 64-bit
    Python 3.10+, sets up a private environment and starts the GUI.
  3. Pick your game folder when asked. That's it.

The Help button (top right) lists every shortcut. The README covers every feature in detail.

What you can do

Asset explorer

  • Browse every file in the game, grouped by category and by in-game area, with search and tabs.
  • View and replace textures (any size, from PNG), and edit UI layouts and text in
    every language, with a notation for colours, button icons and raised or lowered text.
  • Edit the game's data tables (items, crops, recipes, monsters, skills, magic…) with named
    fields. Multipliers show as 1.5× instead of raw fixed-point numbers.
  • Dark mode, adjustable text size, and optional backups with one-click restore.

Map editor

  • Paint collision, place and edit objects, warps, search spots and monster gates, resize maps and
    repaint the ground.
  • Objects are drawn with the game's own sprites and models. Validate checks a map against the
    game's real loading rules before you play.
  • Monster gates: rosters, spawn points, waves and levels, including the gliding and
    teleporting gates of Rune Prana, with their routes drawn on the map.

Cutscene Editor

  • Read and edit every event scene in rf3.mc: dialogue in every language, speakers, faces,
    camera, actors, flags and branches. Add scenes and instructions with a right-click.
  • Reload in game (Ctrl+R) puts your changes into the running game without a restart.
  • The Triggers tab shows what starts each scene: entering or leaving a map, talking to
    someone, defeating a monster, festivals and more. Every trigger type was checked against the
    game.
  • An Event Manager for the game's rule file (em.bin), a Reference of every flag,
    variable and text code, and an optional whole-bank listing (Options → Advanced).

Models and more

  • Export models and animations to Blender and import them back, edit monster AI scripts,
    and work with the game's archives from the command line (rf4mod.py).

Good to know

  • Mods are written into the game's Bundle\ folder. Keep a clean copy of your game, or turn on
    backups (Options → Advanced).
  • The toolkit does not patch RF4S.exe. Everything is done through the game's data files.
  • Requires Windows and 64-bit Python 3.10+ (start.bat handles this).
