+/**
+ * @file psxsn.h
+ * @brief Host file access API header
+ *
+ * @details This header provides stubs for the PCDRV API, which grants read and
+ * write access to a directory on the host's filesystem when the executable is
+ * running on an emulator or through a debugger that supports the PCDRV
+ * protocol, such as Unirom or pcsx-redux. These functions are completely
+ * separate and independent from the BIOS file API and do not register any
+ * device drivers.
+ *
+ * Note that in the official SDK these functions are provided by libsn, while
+ * in PSn00bSDK they are part of libpsxapi.
