This is the applet presented when launching a game that allows the user to select a user.
This has size 0xA0 and seems to only affect the UI display. Typical value is all zero with byte 0x96 equal to 0x01. Setting the first byte to 1 will make the applet display in order to create a new user.
This is 0x18-bytes.
|0x0||0x8||Result (0 = Success, 2 = Failure)|
|0x8||0x10||UUID of selected user|
User-processes should push a common arguments struct and the typical UserSelectionConfig struct as well. After pushing in the data and calling start, user-processes should wait upon the PopOutDataEvent and then pop a single IStorage to obtain the result structure described above.
