This cmd was implemented with [20.0.0+], prior to that this just returned an error.

The sdk user-process func will pass value 1 to the cmd when the input [[#Protocol|Protocol]] is 0/1, ~~3 is~~ passed directly ~~if specified~~, otherwise Abort. User-processes use SetProtocol immediately after initializing ldn.

The sdk user-process func will pass value 1 (2 on Ounce) to the cmd when the input [[#Protocol|Protocol]] is 0, valid values passed directly when recognized, otherwise Abort. User-processes use SetProtocol immediately after initializing ldn.

[20.0.0+] The ldn initialization functionality in sdknso also uses this with value 1 (NX) eventually after the init cmd was used successfully.

Line 540:

[18.0.0+] The sdknso uses SessionManager with this, where the additional session-count is 0x3.

[S2] There appears to be 2 ldn:u services, this appears to be for having separate [[#Protocol|Protocol]] permissions for NX and Ounce games. The Creator object has the same vtable for both of these. However the vtable for IUserLocalCommunicationService appears to be larger even with NX, which likely indicates there's new commands?

The Initialize* cmds configure state the same as using [[#SetProtocol|SetProtocol]] with Protocol NX.

There ~~appears to be~~ S2-only values which enables using Ounce-only keys. The following uses new Ounce-only keys (with S2 hosting):

This is the codebin-region layout for S2 ldn 20.2.0-20.5.0. BuildId is "DC456FA4...".

The on-NX note is for the equivalent memregion location/size, memregion-size/contents compared to NX may vary.

Total size is 0x24F000-bytes.
