Profile Selector
This is the applet presented when launching a game that allows the user to select a user.
See AM_services#Library_Applets. The profile selector expects a two IStorage inputs and a single IStorage output.
Library Applet Versions
| System Version | Value |
|---|---|
| [1.0.0+] | 0x1 |
| [2.0.0+] | 0x10000 |
| [6.0.0+] | 0x20000 |
UiSettings
This has size 0xA0 (0x98 with [1.0.0]) 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. "starter" sets the first byte to 5 in order to display initial user setup.
[2.0.0+]: sdknso ShowUserSelectorForSystem now has an additional input param UserSelectionSettingsForSystemService: u8 +4 is copied to UiSettings+0x96, and u32 +0 is copied to UiSettings+0xA0. sdknso ShowUserSelectorForLauncher now sets u8 UiSettings+0x96 to value 1.
Result
This is 0x18-bytes.
| Offset | Size | Notes |
|---|---|---|
| 0x0 | 0x8 | Result (0 = Success, 2 = Failure) |
| 0x8 | 0x10 | UUID of selected user |
Usage
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.
