VN32X v0.2.0

This is a tool for creating graphic novels for the Sega 32X. Work in progress.

So far, it contains:

  • A C library for making visual novels;
  • Another C library to interface the VN library with the 32X hardware;
  • A tool to convert PNG images to a format compatible with the 32X;
  • A transpiler that translates a subset of the Ren'py scripting language to a C file (plus a few includes) that uses the VN library;
  • A Makefile that takes care of coordinating all of that.

In order to compile the library and the generated sources, you will need a C cross compiler for 32X; you can find one on


A manual can be found at:
