Region map generator
# This is a hacky thrown-together script that procedurally
# generates Gen-3 Pokemon region map images. I intend to build
# an online tool to facilitate this, but this is the first
# proof of concept.
# Requires the opensimplix, Pillow, and scikit-learn:
# pip install opensimplex
# pip install Pillow
# pip install -U scikit-learn

Map Data Conversion

This document is a proposal for how the map data for gen 3 decomps could be converted to a data representation that isn't raw assembler and C. The goal of this data conversion would be to make it simpler for external tools to work with the data. Working directly with assembler and C code takes more effort, is more error-prone, and is less extensible. JSON files are used in this document as the chosen data representation because JSON is widely supported and simple enough for a human to read. The chosen format could potentially be something else, but it should be widely supported (i.e. no custom formats). The work for this proposal is split into several parts:

  1. Convert maps data into individual JSON files
  2. Convert layouts data into a single JSON file
  3. Convert map groups into single JSON file
  4. Create new compile-time tool that transforms these JSON files into their old assembler representations (i.e. codegen).

1. Convert maps data into individual JSON files

Each map will move its data into a si
