Takes a type-0x31 input buffer containing a 0x200-byte struct, no output.
Takes a type-0x31 input buffer containing a [[#GroupInfo]], no output.
[[Mario Kart Live: Home Circuit|mklive]] uses the following string with this: "Failed to create a group: %08X".

Takes a type-0x32 output buffer containing a [[#GroupInfo]] and a type-0x31 input buffer containing a 0x200-byte struct.
Takes a type-0x32 output buffer containing a [[#GroupInfo]] and a type-0x31 input buffer containing a [[#GroupInfo]].
This runs the same code as [[#CreateGroup]] to generate the [[#GroupInfo]] for the input struct (which with [[#CreateGroup]] would be available with [[#GetGroupInfo]]). The input struct is the same as [[#CreateGroup]].

This is "nn::lp2p::GroupInfo". This is a 0x200-byte struct.
[[Mario Kart Live: Home Circuit|mklive]] sets the SSID to a string generated from random data, the key-data is also set to random data.

The above loaded_flags are used when +0x8A is 0. global_flags are loaded from global data. Flags:
* Bit2 clear:
** global_flags must be non-zero, and loaded_flags bit1 must be set.
** u8 +0x8A is set to value 1.
** When the cached [[SPL_services#IsDevelopment|IsDevelopment]] value is false (retail), an error is thrown.
** u8 +0x8B is set to value 0.
* Otherwise, if bit2 is set:
** u8 +0x8A is set to value 2.
** global_flags bit1 set:
*** u8 +0x8B is set to value 1.
** Otherwise, if global_flags bit2 is set:
*** u8 +0x8B is set to value 2.
