Web Config DC VMU Manager

BlueRetro provide a way to emulate memory card through a generic interface internaly. This means all console share the same 128KB of flash memory and that the adapter itself do not provide any facility to format specific format.

The memory card format need to be done either through the web interface or via the target system.

** FOR UNIVERSAL BLUERETRO USER ** Since all systems share the same memory on the adapter for memory card emulation, if you format this area for system X, and then use your BlueRetro on system Y and format the memory card again, you have lost your data for system X. Backup the data with this interface before switching systems.

VMU manager

BlueRetro do not initialise the VMU by itself. Use the Dreamcast BIOS VMU manager to format the emulated VMU memory.

Only one VMU can me emulated on a BlueRetro adapter. You may assign it to any controller via the advance config output config section.

It's possible to assign that single VMU to all controllers but that is likely to create data corruption. DO SO AT YOUR OWN RISK.
