Mounts the save data archive that is in another application.

The save data region of another application is mounted as a save data archive. The other application is specified by specifying its unique ID.

There is no ironclad guarantee that the save data this function is supposed to mount actually exists. For this reason, you need to prepare adequate error handling.

There are restrictions on the unique IDs that this function can specify, so for proper access you need to make the necessary descriptions in the RSF files of the programs that call this function. For details, see the ctr_makerom reference.

The following page has hints on how to handle mount errors. Please use this as a reference.
