Saturn:Phoebe/Rhea

The Phoebe and Rhea are ODEs (Optical Drive Emulator) created by DocBrown that allow you to emulate your Saturn's optical disc drive and run Saturn games without using the disc. Both ODEs physically replace the disc drive and therefore original Saturn discs cannot be used with a Phoebe/Rhea installed. Both originally priced at €130 EU, Phoebe and Rhea are functionally the same but each is made to target different models of the Saturn.

Official installation instructions for Rhea can be found here. Official installation instructions for Phoebe can be found here.

Firmware Updates

 * Firmware update instructions can be found here.

Troubleshooting

 * Solid LED light on power up is usually an indication of an incorrect SD card format. Rhea/Phoebe only uses FAT32 format SD cards. ExFAT formatted SD cards will 100% leave the LED light on.
 * Disc drive ribbon cable can occasionally be inserted backwards or incorrectly. Usually on Saturn dashboard screen, one or two of the floating orbs will be enlarged and red if this happens and ODE won't load. Make sure the ribbon cable is inserted properly.

Controversies

 * Ordering process is non-standard as it isn't a web store. You must subscribe to the WordPress blog and watch for updates when Deunan will have an order window for the specific ODE you need.
 * A strategy that works to secure one is: Once you know a date and time for an order window just set a reminder or alarm 5 minutes prior to the order window time. Just fill-in your information and you'll get an email 2-3 days later for instructions.
