PkGender.py

A Python script to change trainer data (name, gender, etc.) in gen IV Pokémon games (Diamond, Pearl, Platinum, HeartGold, SoulSilver).

• USE AT YOUR OWN RISK!

• Note: NO$GBA prepends .sav files with a header, making them a slightly different format. Please convert to regular .sav files before using this tool.

Setup

• To use the provided binaries, unzip the archive and run the executable normally according to usage instructions.

• To run this script using the Python interpreter, Python 3.6+ is required.

  • It is recommended to run this script inside a conda environment with the fastcrc module installed (through pip).

  • You could also install fastcrc through your system pip (pip3 on Linux).

Usage

• Linux (from a terminal prompt)

  ./PkGender [--name NAME] [--gender] [--verify-only] [--help] [--debug] [--version] savefile
  

• Windows (from a powershell or cmd prompt)

  NOTE: This may or may not work since it was compiled in a weird way (i.e., using wine instead of a Windows system). On my tests, it did work, though, so it should be ok. :)

  .\PkGender [--name NAME] [--gender] [--verify-only] [--help] [--debug] [--version] savefile
  

• Python interpreter (see Setup for dependencies)

  python PkGender.py [--name NAME] [--gender] [--verify-only] [--help] [--debug] [--version] savefile
