Saturn can be powered on with or without SD card in Phoebe, and the card can be replaced while the console is running. To prevent Saturn from booting the 01 image automatically once turned on leave that folder empty and populate the card starting with 02.
When SD card is inserted Phoebe will select image 01. To switch to next image on the card press the button beside card socket. Once the last image on the card is reached the device will jump back to 01.
It is possible to play multi-disc games by either storing all the images on the same card and selecting them with the button, or by swapping the cards.
There is a status LED on the Phoebe, it should blink once during power-up and then remain off. If the LED is lit, or starts blinking during gameplay, an internal error has occured. There are many possible causes of that, including SD card data transfer errors. The only way to restart correct operation of the device is to power-cycle the entire console. If the problem persists try a different card brand/size. If nothing else helps file a bug report.
A simple text INI file can be put into root folder of the SD card to modify some of the Phoebe default settings. The file should be named Phoebe.ini.
IMPORTANT: Settings are read during SD card detection phase, so changing the card will result in Phoebe re-reading them again. This way it is possible to have different settings per card. If no INI file is found, the previous values will remain in effect.
- open_time = N
Where N is natural number in range 150 to 5000, expressed in miliseconds. Defines how long GDEMU will idle with “lid open” status presented to the console after image change. Default is 500ms.
- detect_time = N
Where N is natural number in range 150 to 5000, expressed in miliseconds. Defines how long GDEMU will idle with “busy” status presented to the console after image change. Default is 250ms.
- image_tests = B
Where B is 0 (disabled) or 1 (enabled). If disabled, image integrity tests will be relaxed to allow oversized media. Note that correct operation is not guaranteed with such images. Default is enabled.
- high_speed = B
Where B is 0 (disabled) or 1 (enabled). If enabled, GDEMU will transfer data from SD card in high speed mode . Note that this is an experimental option and might not work properly. Default is disabled.
- auto_region = N
Where N is the code for your console region, or -1 to disable the patcher (the default setting). The codes can be specified in numeric or single letter format:
0 (or J): JAPAN, 1 (or T): TAIWAN and PHILIPINES, 2 (or U): USA and CANADA, 3 (or B): BRAZIL, 4 (or K): KOREA, 5 (or A): ASIA PAL area, 6 (or E): EUROPE, 7 (or L): LATIN AMERICA
- auto_freq = B
Where B is 0 (disabled) or 1 (enabled). If enabled, Phoebe will force VDP2 vertical refresh frequency to either 50 or 60 Hz, depending on the region of selected image. Default is enabled.
