REasy Editor v0.1.6

REasy Editor is a quality-of-life toolkit for RE games that currently supports viewing and editing of some RE Engine files. It also includes miscellaneous tools to speed up your work. I have currently rushed the release and the structure will be improved in the upcoming updates. Supports RSZ files (SCN, PFB, User) from all games

Features

File Type	Viewing	Editing	Tested On
UVAR	✅	✅	RE4, RE2
RCOL (temporarily disabled)	❌	❌	RE4
SCN	✅	✅	RE4, RE2, DMC5, RE2 RT, RE8, RE3, RE7, SF6
User	✅	✅	RE4, MHWS (Should work on other games)
PFB	✅	✅	RE4, RE2, DMC5, RE2 RT, RE8, RE3, RE7, SF6

• UVAR File Editing:

  • View and fully modify UVAR files. Hashing and mapping are taken care of automatically.
  • Add new variables with automatic naming that preserves numeric formatting (e.g. "Location47_031" followed by "Location47_032"). This allows you to add new flags to RE4R for example (which was not possible with existing tools).
  • Deletion of variables is also supported.

• RSZ File Viewing and Editing:

  • User, PFB and SCN files are supported with advanced editing.
  • GameObjects and Array Elements are fully serializaible into JSON.
  • You can export and import GameObjects in RSZ files through REasy using the Template Manager. Exported GameObjects can be found in the "templates" directory in plaintext (JSON).

• Search Functionality:
  Search all files across directories for:

  • Specific text (UTF-16LE encoded)
  • 32-bit numbers (with hexadecimal display)
  • GUIDs (with conversion from standard format)

• GUID Converter Tool:
  Convert between memory (hyphenated hex) and standard (hyphenated) GUID formats.

• Dark Mode:
  Toggle a dark mode theme that applies to all dialogs and windows.

Unique Use-Cases:

• Adding New Flags to RE4R:
  I tested adding 22000 new flags (file size went from 2mb to ~16mb), and tried some of them randomly. Game was stable. At 50k added flags, it crashes when a gamesave is triggered. To determine the exact threshold, your testing and feedback are needed. But 20k should be more than enough. (I wrote a guide here)

• Finding all files where some data is referenced: Ever encountered a flag but don't know in which file it is set? This tool allows you to find all locations where that flag is checked/set.

Correctness

• UVAR: No complex operations involved.
• RSZ Files: RSZ parsing and tree populating tested on all 25k .scn.20 files of the game as well as all .user.2 files. All files with valid data passed the tests.

TODO List:

• The entire project needs to be ported into .NET

Installation

• Run build.bat

• Dependencies in requirements.txt
