ACT Services
The ACT module handles NNID accounts. This module behaves very similarly to the Wii U implementation (nn::act)
ACT service "act:u"

Account slots
Like the friends sysmodule, the ACT module supports multiple accounts internally, although this functionality is not exposed to the users. Unlike the Wii U which supports up to 12 accounts, the 3DS only has 8 account slots.
Some commands require require the account slot as an argument, which is 1-indexed. The value for using the current loaded account is 0xFE.
DataBlocks
Data blocks can be accessed from specific commands depending on the data that is requested. These follow a similar order to the Wii U ACTInfoTypes.

HTTPS Requests
With each request, ACT-sysmodule specifies request-header "X-Nintendo-Device-Model". This is the only *dedicated* request-header that's contains anything Old3DS/New3DS specific. This was implemented with 9.0.0-X, and presumably 8.1.0-0_New3DS. The value is from a string initialized during ACT-sysmodule startup. The value-string is the codename string for all 5 of the model values from Cfg:GetSystemModel. When the output from GetSystemModel is >=5(switch statement default case), it runs this: "len = snprintf(outstr, outmaxsize, "3DS-%u", model);"
Trusted Root CAs
ACT module uses a RootCertChain for all HTTPS requests, the only trusted root CA is default CertID 0x3.
New3DS
Even though ACT-sysmodule uses ptm:s, it doesn't use CheckNew3DS at all.
