Version 0.0.1 is now available!

Github repo: https://github.com/haroldo-ok/choice4genesis

This is a ChoiceScript clone that generates Sega Genesis ROMs. If can be used for visual novels or simple multimedia presentations.

It takes a bunch of scripts and images and, from that, it generates SGDK-compatible .c and .res files. Those are then compiled into a Sega Genesis compatible ROM, which can be run on an emulator or even on real hardware.

The syntax of the scripts is somewhat based on ChoiceScript, but it is not exactly the same.

Please note that this is an early work and progress, and it is not as stable or user-friendly as it is planned to become.

Commands implemented so far

font

Loads a .png file containing the 8x8 font. Note that the image must be paletized, with 16 colors. Future versions of this tool will probably convert the image automagically.

Loads a .png file as a background image. Note that the image must be paletized, with 16 colors. Future versions of this tool will probably convert the image automagically.
