This package is CTR Pia 4.11.3, the peer-to-peer communication library for CTR.
Master submission of ROMs created using the following features of this package is prohibited.
Consult with Nintendo in advance when you need to submit a master ROM using non-release versions of these features.
The following table shows the current support status for each module.
| Module Name | Feature | Status |
| clone | ReliableLargeCloneElement | Beta |
For more information about unsupported features, see the top page of each module in the Programming Manual.
Make sure that flag definitions, used when including header files for this library, conform to the flag settings for the build system included with the CTR-SDK.
Specifically, for release builds, you must not define NN_BUILD_VERBOSE, NN_BUILD_DEVELOPMENT, NN_BUILD_DEBUG, or NN_BUILD_NOOPT flags.
For development builds, you must not define NN_BUILD_RELEASE, NN_BUILD_DEBUG, or NN_BUILD_NOOPT flags.
For debug builds, you must not define NN_BUILD_RELEASE or NN_BUILD_DEVELOPMENT flags.
For more information about flag definitions for each build, see the CTR-SDK build system. Applications may not run normally if they are built by using flag settings that differ from the build system included in the CTR-SDK.
The CTR-SDK must be installed to use CTR Pia. CTR NEX must also be installed to use Internet communication. CTR NEX is not necessary if you are using local communication only.

The following table lists the maximum number of connected devices supported by each module. The number in parentheses represents the maximum number of devices that can run, but it is not supported. We will consider increasing the number of supported devices if requested.

| Internet Communication | 12 | 8 | 12 | 12 | 12 |
| Local Communications | 8(12) | 8 | 8(12) | 8(12) | - |
Expand this package in a directory with a name that includes neither spaces nor Japanese characters. To build sample demos, you must set the following environment variables.
Set the following path as the include path, and include the header file that corresponds to the module you want to use (such as common.h, local.h, etc.).
$(CTRPIA_ROOT)\include\
Link the libraries in the following path according to the build target.
$(CTRPIA_ROOT)\libraries\
This package only includes the fast build of the library. P2P communication, where the CPU load can easily create a bottleneck, normally uses only the fast build. For this reason, and to fully verify the fast build, the small build is not included. If you need the small build, please contact Nintendo.
Run omake in $(CTRPIA_ROOT)\sampledemos\.
After building the samples, run omake in $(CTRPIA_ROOT)\tests\.
If you are developing an application that supports network services, you must apply on the Online Title Management System (OMAS). If you are using the Pia library, be sure to select Pia as the P2P library being used in the entry in the NEX Matchmaking section of the OMAS application.
