A tool to autosort disc images and autogenerate RMENU entries for the GDEMU Phoebe/Rhea Sega Saturn ODE

gODESort

Purpose

The GDEMU Phoebe/Rhea optical disc emulators (ODEs) are fantastic hardware mods that allow you to replace the physical CD drive in a Sega Saturn with an SD card and load disc images on original hardware - unfortunately the GDEMU ODE is extremely picky about how the disc images are ordered, named and otherwise laid out on the SD card filesystem.

Grouping disc images into categories requires "dummy" folders with specific text files and further complicates ordering, especially with a large number of images.

This tool is designed to be pointed at your SD card root and executed and currently supports the following operations:

• godesort sort -i /path/to/your/sdcard will automatically alphabetically order your images, fix folder numbering gaps, and automate image (re)ordering after any additions or removals
• godesort generate -i /path/to/your/sdcard will scan your sorted images, regenerate the RMENU INI file, and rebuild the RMENU ISO-based menu that Phoebe/Rhea boot into.

NOTE: gODEsort builds the RMENU menu using the image filenames for the menu entries, rather than the disc header titles that the native RMENU tool uses - which means you can simply name your images according to how you want them to be displayed and ordered in the RMENU menu.

Note: Currently gODESort only works with CCD image types and the Phoebe/Rhea ODEs - support for the Dreamcast GDEMU and other image types is pending

Prerequisites

• Install cdrtools for your platform- specifically, mkisofs must be in your path
• Install the Go runtime for your OS
• Have the latest RMENU files extracted to a folder named 01 at the root of your SD

Installation

Currently the only way to install is to build from source.

Supports any OS Golang does - Win/Mac/Lin

1. Clone this repository

2. Build the source

   cd godesort
   go build

Usage

Note: This tool will not touch the "01" folder on your SD card since that is typically reserved for RMENU - all image folders will be renamed starting at "02"

1. This tool sorts your images based on the image filenames so make sure your images are named like you want them - e.g.

   45/ ->
        Virtua Cop.ccd
        Virtua Cop.img
        Virtua Cop.sub
   

2. Run the command and point it at your Phoebe/Rhea root

   ./godesort -i <path-to-your-sdcard-root> sort

3. Done. Rerun the above command as needed after adding or removing images to your SD card root to keep things ordered.
