## Description

Initializes the system in the same way as the `OS_Init` function and then confirms hardware launch restrictions.
If an application designed for China is launched on a Nintendo DS system that is not localized for China, the launch of the application is restricted, and control does not return from this function. If an application designed for China is launched properly on a Chinese-market Nintendo DS system, this function displays the health and safety cautions screen and informs the user of the mandatory information, such as the ISBN number. To make an application for China, you must use this function instead of the `OS_Init` function and define accompanying information in the ROM image that indicates that the application has Chinese-language support. For more information, see the description in `makerom`.
For information about system initialization, see the description for the `OS_Init` function.
