Rhea/Phoebe Sorter (The Orbital Organizer)​

SD card sorter for the Sega Saturn ODEs Rhea and Phoebe.

This utility is designed to streamline the process of adding/removing games from an SD card compared to the traditional RMENU rebuild process.

It can be used for both first-time SD card set-up, as well as for users with a pre-existing Rhea/Phoebe SD card.

Please note that whether one is setting up a first-time SD card or managing a pre-existing one, the 01 folder on the card must contain all of the necessary RMENU or RmenuKai files and folders.

With only this 01 folder present on a brand-new SD card, the card's structure should appear as follows (with the drive letter F: as an example).

Code: 
F:\
|   Rhea.ini (or Phoebe.ini)
|
\---01
    |   RMENU.exe
    |   RMENU.iso
    |
    \---BIN
        |   mkisofs.exe
        |
        \---RMENU
                0.BIN
                IP.BIN
                LIST.INI
                Z.BIN

Current Version​

Rhea/Phoebe Sorter is currently at version 1.6.

Changelog​

  • Version 1.6 (2025-05-10)

  • Version 1.0 (2024-10-18)
    • Initial release.

Known Issues​

As of the latest version of Rhea/Phoebe Sorter, multiple game entries sharing the same labels are not supported if they are multi-disc games that are nested into one or more virtual subfolders (e.g., /Games/RPGs/Grandia (T-En)/Disc 1). However, multiple game entries sharing the same labels are supported for single-disc games that are nested into one or more virtual subfolders (e.g., /Games/Shooters/Radiant Silvergun).

Additionally, multiple game entries cannot point to the same disc image in the latest version of Rhea/Phoebe Sorter. This is sometimes seen with RmenuKai users who have a genre-separated list, as well as a simple "A-Z" listing.

Converting Disc Images to CloneCD Format​

Those new to the Rhea/Phoebe ODE may wonder the best methods for converting disc images to CloneCD format (i.e., CCD/IMG/SUB). There are several options, including batch conversion. In general, the below methods support conversion from any valid disc image that uses a .CUE file for its table of contents (e.g., CUE/BIN, CUE/ISO, CUE/ISO/WAV).

  • CUE2CCD
    1. Drag .CUE file onto cue2ccd.exe to perform conversion of a single disc image.
    2. Converted disc image will be generated in a folder named CCD.
  • Sega Saturn Patcher (link to latest version not yet available on SegaXtreme)
    1. Launch application and then choose "Select Saturn Game".
    2. Click "Rebuild Image" at the bottom-right of the application.
    3. Under the "Save as type" dropdown, select CCD/IMG file (*.img).
    4. Navigate to desired output location and then click "Save" to generate converted disc image.
  • batch_convert_cue_to_ccd.bat
    1. Ensure that CUE2CCD is downloaded and in the same folder as batch_convert_cue_to_ccd.bat.
    2. Drag a folder containing disc images to be converted directly onto the batch script. Note that any degree of nested subfolders is supported.
    3. Console output will appear with status update messages, and original disc images will be deleted and replaced with converted ones.
  • Disc images using a .CUE file for their table of contents can be mounted with applications like DAEMON Tools and then dumped to CCD/IMG/SUB with CloneCD. Note that newer versions of Windows are known to cause issues with this method in some cases. If none of the conversion methods listed here are yielding a successfully booting CCD/IMG/SUB disc image and DAEMON Tools combined with CloneCD on a modern version of Windows is also failing to produce a working disc image, provision a Windows XP virtual machine. Then, use DAEMON Tools v3.47 to mount the source disc image. Lastly, dump the disc image mounted in the virtual CD-ROM drive to CCD/IMG/SUB using CloneCD, or to CDI using DiscJuggler v6.00.1400 (link 1, link 2). Rhea/Phoebe supports both CCD/IMG/SUB and CDI formats.

Basic Usage​

#f03c15 IMPORTANT: Rhea/Phoebe users with a pre-existing SD card must first undergo a migration process described in the Menu Migration for Pre-Existing Rhea/Phoebe SD Cards section.

Using Rhea/Phoebe Sorter is simple, with each operation to be carried out according to the instructions below.

Adding New Games​

  1. Create a folder on the root of the SD card, giving it whatever name should appear in the RMENU/RmenuKai game list.
    • Should a label be desired that contains characters that are restricted in file/folder names (i.e., <, >, :, ", /, \, |, ?, and *), create a file named Name.txt inside of the game disc folder containing said label.
    • For multi-disc games, append - Disc X to the end of the folder name (or to the end of the label stored in Name.txt). This format must be adhered to for proper processing of multi-disc games. See examples below.
      • Policenauts (T-En) - Disc 1
      • Enemy Zero - Disc 2
    • If wishing to present the disc image inside of a virtual folder path with RmenuKai, create a file named Folder.txt inside of the game folder, storing within it the full path (e.g., Games/Action/Platformers).
  2. Copy the disc image (in a supported format) to the newly created game folder.
  3. Drag the SD card onto orbital_organizer.exeand watch the status messages until processing is complete.
    • Rhea/Phoebe Sorter will alphanumerically sort all numbered folders based on game name (and virtual folder path if using RmenuKai), as well as automatically extract metadata (i.e., disc number, release date, version, and region) from each disc image so that RMENU/RmenuKai can display it. It's worth mentioning that Rhea/Phoebe Sorter's method for extracting said metadata is more reliable and accurate than that of the traditional REMENU rebuild process.

Removing Existing Games​

  1. Open GameList.txt in the root of the SD card and then identify the numbered folder containing the disc image to be removed.
  2. Remove the identified numbered folder from the SD card.
  3. Drag the SD card onto orbital_organizer.exe and watch the status messages until processing is complete.

Changing Game Label, Virtual Folder Paths, and Other Metadata​

  1. Open GameList.txt in the root of the SD card and then identify the numbered folder containing the disc image with metadata to be edited.
  2. Open the identified numbered folder, then open and make changes to the appropriate text file.
    • Date.txt - The game's release date
    • Disc.txt - The game's disc number
    • Folder.txt - Optional virtual folder path for RmenuKai
    • Name.txt - The game name as it appears in the menu list
    • ProductID.txt - Optional new Product ID (see the Modifying Product ID section)
    • Region.txt - The game's region code
    • Version.txt - The game's version as specified by publisher
  3. Drag the SD card onto orbital_organizer.exe and watch the status messages until processing is complete.

Modifying Product ID​

The Product ID is a piece of metadata associated with Sega Saturn games which ties a piece of software to a unique identifier. There are cases where users may wish to populate a missing Product ID for homebrew software, or fix incorrect Product IDs like that of the Japanese version of "Virtua Fighter Kids" where GS-9079 is stored on the disc but the correct ID is GS-9098.

If desired, Rhea/Phoebe Sorter allows users to modify this ID by directly patching the disc image's IP.BIN header.
  1. Open GameList.txt in the root of the SD card and then identify the numbered folder containing the disc image for which the Product ID should be modified.
  2. Open the identified numbered folder, then create a file inside of it named ProductID.txt containing a new ten-character ID. Fewer than ten characters is acceptable, but any ID exceeding ten characters will be trimmed.
  3. Drag the SD card onto orbital_organizer.exe and watch the status messages until processing is complete.
Note that after adding a ProductID.txt file to a game folder and processing the SD card, it will be automatically removed so that its disc image won't be unnecessarily patched again during future SD card processing.

Multi-Disc Games with RmenuKai​

If Rhea/Phoebe Sorter detects RmenuKai on the SD card, the user will be asked if they'd like to use virtual subfolders when processing multi-disc games. If the user says "yes", multi-disc games will only consume one entry on the RmenuKai game list. Upon selecting one of these multi-disc games, a subfolder will be displayed where each separate disc appears as a selectable entry.

For organizational purposes, it's highly recommended that those using RmenuKai allow Rhea/Phoebe Sorter to undergo this intelligent processing of multi-disc games.

Adding an Instance of Legacy RMENU Alongside RmenuKai​

Users of RmenuKai may wish to preserve an instance of legacy RMENU for certain niche use-cases (e.g., use cheats for a JHL loader game).

While users of a Gamer's Cartridge can achieve this by leaving legacy RMENU on their SD card while RmenuKai resides only on the cartridge, most Gamer's Cartridge users prefer to keep RmenuKai on their SD card in addition to their cartridge. This is useful for several reasons beyond the scope of this documentation.

Whether using RmenuKai strictly via SD card, or using it via SD card coupled with a Gamer's Cartridge, Rhea/Phoebe Sorter supports an instance of legacy RMENU that can live alongside RmenuKai and be launched directly from the game list menu.
  1. Create a folder on the root of the SD card, giving it whatever name should appear in the RmenuKai game list (e.g., RMENU).
  2. Drag the SD card onto orbital_organizer.exeand watch the status messages until processing is complete.
    • A message will appear informing the user that a secondary instance of RMENU was detected on their SD card, at which time they'll be asked if they'd like to update said instance with the latest game list data. Choosing to do so will result in that instance of legacy RMENU containing an up-to-date list of disc images for selection.
Note that this secondary instance of RMENU (in this case, legacy RMENU) will not reside in folder 01. Instead, it will occupy a different folder number based on its place in the disc image list.

It is suggested to leverage RmenuKai's virtual folder path support to store legacy RMENU in a folder named Utilities and Applications or similar. To achieve this, before processing the SD card create a file named Folder.txt inside of the legacy RMENU folder containing the desired virtual folder path.

Menu Migration for Pre-Existing Rhea/Phoebe SD Cards​

For those with a pre-existing SD card who wish to use Rhea/Phoebe Sorter moving forward, a one-time migration process must be carried out. Note that this migration process fully honors virtual folder paths as defined in an RmenuKai-formatted SD card.

Before undergoing this migration, consider the following example Rhea/Phoebe SD card.

Code: 
F:\
|   Rhea.ini
|

|   |   RMENU.exe
|   |   RMENU.iso

To perform migration, drag the SD card onto orbital_shift.exe. It will produce output similar to the below.

Code:

WARNING: Before proceeding, ensure that no files or folders on SD card (F:)
         are open in File Explorer or any other program. Failure to do so
         will result in data corruption!

Press Enter to continue...

Reading existing menu data...

RmenuKai has been detected on SD card. Virtual folder paths will be honored
during migration process.

-> Renamed folder "07" to "Grandia (T-En) - Disc 1"
-> Renamed folder "08" to "Grandia (T-En) - Disc 2"

First phase of menu migration is complete!

Next, drag SD card onto "orbital_organizer.exe" to rebuild RMENU.

Press Enter to exit...

Afterwards, the structure of the SD card will change. Notice how games are now stored in folders named after the game itself, and Name.txt files are present for disc images whose labels contained characters that are restricted in file/folder names.

Additionally, because this example SD card was formatted for RmenuKai, Folder.txt files are present for games that had virtual folder paths associated with them.

This structure, seen below, is how new games will be added to the SD card in the future before being processed by Rhea/Phoebe Sorter.

Examining the contents of the GameList.txt file generated in the root of the SD card reveals the following, where disc images labels, along with their virtual folder paths, are easily identified.

Code: 
01 - RMENU
02 - /-Demo Discs-/Bootleg Sampler (Version 1)
03 - /-Homebrew-/Blue Skies (PRGE 2022: Game Pad Version)
04 - /-Media-/-CD+G-/Alphaville: The Breathtaking Blue
05 - /-NetLink-/Daytona USA CCE
06 - Advanced V.G. (JP)
07 - Grandia (T-En) (Disc 1/2)
08 - Grandia (T-En) (Disc 2/2)

Additionally, one can see the contents of \01\BIN\RMENU\LIST.INI to uncover precisely what metadata was used to generate a new RMENU/RmenuKai ISO.
